I have had 5 jeeps, YJs, TJs and even in MJ. They all had the death wobble in various forms. This is probably the best discussion of the issue. It is a beast to track down.
@@IronRockOffRoad agreed. I owned a YJ and several friends owned YJ’s too and no one ever complained of death wobble with leaf springs. I don’t think it’s possible unless the shackles or u bolts on the perches are loose
@@Saturnian4417 You never know. If someone did get DW with leaf springs I wouldn't be too surprised. I do know we would try our best to help a YJ owner get to the bottom of the issue though.
Ball joints can also contribute to the problem. I went through all of your checklist items on my 2017 Rubicon and still had a wobble. New tires, alignment, 1 ton tie rod ends, Teraflex oversized track bar, etc. all made improvements, but never totally fixed the wobble. Changing the ball joints to the Teraflex adjustable ball joints made it rock solid. I don't know how that can be the problem, even the alignment shop said ball joints would not cause death wobble, but it was. And all that we could see was slight play on the driver side lower ball joint. It drives perfectly now. I would add it to the checklist.
Ahh, thank you, If you look on page 2 of the checklist, we do have you check your ball joints 🙂 www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf
Look on line, many jeeps with stock wheels and less than 500 miles are expieriencing this issue including my wifes 2022 with 12000k. More to come on this issue. So far Chrisler has ignored the issue. No recall to date.
thanks for your video. My wife's JT had death wobble. Not bad, but enough to make it un-nerving. Read up a multiple other pages and watch a few videos about death wobble. Upgraded a couple steering parts ( drag link, trackbar that was planned to be upgraded this summer anyway). Did everything on the other's pages list (Tightened everything, removed one piece at a time and checked the bushings, checked the shocks, tire pressure..... with no change. Watched your video and the checklist. You talked about and provided numbers about tow. Down to my last straw and doubting it would work.... I took two pieces of angle iron and rubber clamps to clamp the angle iron to the rotors. Leveled the angle iron to the ground, plum bob from the center of the hub down to the angle iron to mark the center, then measured out a foot both ways. Measured across and found it towed in 1/8". Adjusted to 1/32". Death wobble gone. (Honestly, I doubted it would fix the issue and was surprised) . It's been two months with no signs of it. My wife is happy, So I'm happy.
I used to work in a shop that specialized in suspension and alignments. 90% of the time death wobble is caused by a bad trac bar, loose trac bar bolts, or incorrect castor settings. Ignore the factory castor settings if your rig is lifted and has bigger tires, as the effective castor angle changes as the distance from the ball joints to the ground changes. A steering dampner can not cause or repair death wobble, regardless of how many techs tell you it can. A dampner can only mask a problem, not create one, unless it is physically damaged and binding up. Dealerships specialize in replacing parts, not fixing problems. I can not count how many Jeeps I've had to fix after it left the dealer with a new steering stabilizer, but still had death wobble.
@@IronRockOffRoad This video reminded me... The other day I was looking on your website for something I thought I remembered you sold, but I couldn't find it. Track bar oversize bolt and nut insert kit thingy for a Jeep WJ. Have you still got a part number for this item?
Great info. Thanks so much. Lesson here is if you don’t know what you’re doing, take it to a shop that does and listen to what they say and if it’s a good shop, replace what they tell you needs to be replaced. Again awesome video.
so many people go straight to the Steering Stabilizer as the cause, because they do not want to take the time and effort to track down the real cause. You did a great job at explaining the procedure of tracking down and by offering a check list.
In my case the steering stabilizer did start to leak. Which i believe is the root cause of my death wobble on my jeep. But will be replacing the whole steering kit together to make sure
@@zer0luink I don't think it is. some people take their steering stabilizer off completely and run with out one. most of the time it is a wearable part such as a bushing, worn out bolt holes and joints. Ball Joints, Tie Rod Ends, Track Bar Bushings and the Brackets they bolt to. a new steering stabilizer is a Band-Aid, it appears to solve the problem but it only covers up the problem and ruins the stabilizer later on.
Had my jeep for 22 years. Death wobble was a issue about 10 years of owning it. Replaced all the bushing on the front end of the Jeep. Control arms etc... from rubber to polyurathane and not only did it fix the issue but I have not had death wobble since. 2001 TJ.
@gmac9956 Unfortunately, that is a story we hear often. The stabilizer is certainly doing something to mitigate the death wobble, but it isn't the solution. We always recommend going through the entire DW checklist to be certain everything is good, but on the JL & JT we frequently see the joint at the pitman arm fail. We created an OEM replacement joint for that spot that is much bigger and stronger. It is a much less expensive option than a completely new steering system and can easily be done in the driveway with common hand tools. www.ironrockoffroad.com/95181.html ruclips.net/video/XUsS0JVzpwc/видео.htmlsi=zqeqXfn3Z8c4ImqN If you ever need help you can give us a call and talk to a real person! 9-6pm Central time 952-210-7185 Or shoot us an email tech@ironrockoffroad.com
Do note, fully extended the damper. They tend to have dead spots after full extension. Also the damper absolutely has been an issue many times. They basically turn into a spring when bad. The big thing I see is customers, and a lot of techs don’t know the difference between death wobble, and a minor steering shimmy. The shimmy is almost always the damper, and Dosent occur when removed. The death wobble is almost never the damper
The Jeep we were working on in this video had a good stabilizer. When it was installed, the shimmy was less than when we took it out. Then we went through our checklist and were able to make the jeep drive solid, without a stabilizer installed.
I'm at 8deg + on a 6" lift heavy diesel JT. The lift manufacturer wanted 6.5deg at 3.5" lift. A bit of tuning finds the right amount. It's not as much of a factor in death wobble. The JT and JL Wrangers are really sensitive to wheel balance. In addition, the front drag link and track bar as factory units wear very quickly with any amount of lift and offroading schedule. Just replace them with 1 Ton options. Mine were very loose at 9k miles.
@@iamblaineful yes, thank you for pointing out that sometimes a bit of tuning may be needed. Lift manufacturers do their due diligence to offer a good starting point for alignments, however, people set up their Jeeps in an infinite number of ways so it's impossible to say an exact number will work with all Jeeps.
I have used iron rock off-road products for Uber 5 years to defeat death wobble you can stabilize your steering box with their products you can stop your tie rod from flexing these products are top-notch and I would highly recommend for an XJ with death wobble the heavy duty solid steel tie rod.
Excellent Video! Thank You! I am not having the death wobble often, but it does happen when I hit a bad part of the road every now and again. I do have a lot of upgrades, full King Coil-Overs, large over-sized tie rod, track bar, drag link and large polygon upper and lower control arms. Not sure about the links and I believe my pitman arm is a stocker. I am at max tires with 40's on 20' KMS Grenade bead-locks. Wish I could show you a picture. Anyways, I did download the checklist and will be going through the steps as I don't want the wobble to happen when my daughter drive the Jeep. BTW, it is a 2020 Rubicon / Recon. Like I said, I don't get the wobble very often and I make the drive from S Florida to upper Michigan at least once a year to hit trails with my 5 brothers and da; we all have Jeeps. Again, thank you for the video and all the info on your website. If anything I have stated here stands out to you, please yell at me and let me know LOL
Great video, that said, I would have liked you to repair/replace one item at a time ( starting with tire rotation) to see if one item was the cause of the death wobble. Understanding that it may have been more than one item.
Because we know that any looseness or imbalance can cause steering shimmy, we went ahead and fixed all known issues right away. But we agree, that would have been a fun test, if nothing else, to see what changes in the shimmy (severity, speed) based on each single change.
I had a serious Death Wobble in my 2021 Deisel JL. The wobble started at about 4,500 miles. We had to replace almost every major part in the front end before we got rid of the wobble. The only thing we didn't have to replace were the ball joints. I am at 27,000 miles now and still watch it closely in case it returns.
@stevenwilson229 We're glad to hear you haven't had any death wobble! We are here to help if you do have any death wobble in the future. I hope you'll give Iron Rock a look for some of your next Jeep upgrades.
In the early 80s I had a great 78 jeep Cherokee chief top of the line rig with locking differentials..it had a death wobble, very scary. Fixed it with a heavy duty steering stabilizer..
Fixed my 2011 Wrangler Sport ( 2" lift springs) with adjustable front lower control arms, measured the stock ones and added 1/4" - 3/8" to the adjustable ones.
Can you just use adjustable lowers and not change uppers? Ball joints and adjustable CAs are phase 2 if phase 1 (drag link, TREs, new tires and alignment) doesn’t work.
What do you do when the death wobble is on a brand new Jeep like mine. I purchased a brand new 2019 Jeep JL Rubicon Unlimited It started to death wobble 2 weeks after I purchased it with less the 400 miles on it. It was so new that the dealer had no parts to fix it. After a month or so they put a new steering damper on it. It lasted maybe 2000 miles and death wobbled again, any way it is on it's 4th damper and the Jeep only has 16000 miles on it and starting to get that feeling again. Jeep refuses to replace the aluminum steering box because they claim it's not the problem. I have a Jeep that I don't trust and one my wife refuses to drive and no help from Jeep. I have a 7 year 70K bumper to bumper warranty which does no good if they can't fix the death wobble. I feel that I shouldn't have to spend thousands of dollars to repair a Jeep that was not right from the factory. But I will end up taking it the shorts to sell or trade it. Next vehicle will be a Toyota 4Runner TRD pro.
It's unfortunate many dealers are incompetent what it comes to suspension and steering diagnosis and repair. However many dealers have excellent technicians who are very knowledgeable and able to help you. Stand your your ground when you bring it in, stating that the condition recurs even after multiple attempts at throwing a steering stabilizer at it. Our guess is that some other loose/worn/improperly adjusted or balanced part(s) are attributing to the problem, and prematurely overstressing your stabilizer to the point of failure. Insist that they watch this video and complete the tests within our steering shimmy checklist: www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf
I have a 95 series 80 Landcruiser 3” lift running 33” tires with close to 400,000 miles and have never had DW. However, bought a new jeep for my daughter…hence why I’m reading all your comments. I bought a new bronco for my other daughter…NO Problems 😮
@theadventuringcoonclan1942 Thank you for the complement! We're still coming out with new products for the WJ so keep us in mind for your next upgrade!
4 degrees of + caster is way too low, IMO. A slight toe out helps to mitigate DW. That's per the engineers at Steer Smarts. A sector shaft brace, like the one from Metalcloak, is highly recommended. A common issue is that a steering stabilizer will mask DW until it's worn out from being overworked. As you mentioned in your process, a properly setup vehicle will drive with no DW with the stabilizer removed, but it's an easy and cheap bandaid for dealerships. Finally, or perhaps foremost, get a good torque wrench and go over everything when you get home from the dealership. Too many Jeeps are delivered with loose steering box bolts, loose Pitman arm nuts, loose control arm bolts, loose ball joints, and more. It's like they don't even own a torque wrench in Toledo. It's scary the stuff they let go.
Thanks for your feedback. Depending on the Jeep, lift height, and other accompanying modifications, a wide range of caster could be used. Reducing caster in most cases does reduce steering shimmy. We produced our death wobble checklist over 15 years ago, and have always maintained that a slight tow out can help with steering shimmy. If other manufacturers are agreeing, that solidifies our recommendation. We can't agree with you more about double checking torque on all your suspension and steering fasteners. That is good practice whether you are experiencing an issue or not. Especially 200-500 miles after an initial installation, and after any moderate to heavy or high speed off road driving.
I absolutely love these tail lights. I have been looking for something completely different, and I have found them. Please let me know if you can make a pair for a 2016 Jeep Wrangler Sahara unlimited
Can you do an overview of the front bumper setup on this Jeep? I have the same bumper but without the winch. I want to add a winch, but I don't know what that would entail.

@Re-DeclarationOfIndependence Thank you for the complement! The checklist is the result of 20 years of first-hand experience that we are happy to share. We want everyone to be able to enjoy their vehicle as much as we do!
@@IronRockOffRoad I got tires balanced, replaced tierod, tackbar, drag link, replaced upper and lower control arms. I’m planning doing the upper and lower ball joints. The dramatic wiggle is still there. I’ll continue to go through the list, but any other encouraging suggestions during the process?
@Re-DeclarationOfIndependence You are on the right track! Don't forget to check your toe alignment and wheel bearings. Most of us Jeep guys are running bigger, heavier tires that put added stress on wheel bearings. If there is any play in them, a bigger tire will be able to wander and put the toe alignment out of spec. Luckily, on a solid axle vehicle like a Jeep it is easy to check and adjust the toe setting at home. Wheel alignment tool: www.ironrockoffroad.com/product/wheel-alignment-tool.html
None of the manufacturers put stiff enough track bar, drag link and tie rods in live axle vehicles. Replace all three with heavy duty components and you don't need a steering stabilizer. Stabilizers just mask the problems until they get to a point where the problems are too big to mask.
The steering stabilizer still is an important part of your steering system. We agree, most people don't understand what the steering stabilizer is for and assume it is the fix. Check out our video on steering stabilizers: ruclips.net/video/2giiC8Oruh8/видео.html
What about them negative offset wheels with bigger, heavier tires in conjunction with the wheel spacers ..they push the wheels out and multiply the stress on the steering components, especially the tie rod and ends.
@MrTurbo64 you're absolutely right about the compounded stresses added with these types of additions. In many cases, it's a necessary compromise when the vehicle owner wants to run larger tires without clearance problems. The good thing is, we have developed steering systems with larger, and more heavy duty tie rod ends and linkages, that drastically improve longevity in those components in a higher stress environment. Many don't realize the facts you brought up and how they can affect other vehicle components. We are here to answer any questions you may have when doing your build.
2019 Wrangler with death wobble. Dealerships saying it’s the steering stabilizer. Been through two stabilizers in 2,000 miles! What’s the root cause of this? Welding issues?
@SeizetheAuraRosaliesRareHe-p1d The steering stabilizer gets the blame a lot on the newer Jeeps. We were told the same thing by our local dealership and had it replaced a couple times. I'd recommend going through our death wobble checklist or giving the checklist to a reputable mechanic that you trust. On the 2019 and newer Jeep Wrangler and Gladiator we have often times found the steering joint at the pitman arm to be loose as well as the track bar joints. These parts wear out prematurely.

I have a weird one, Off road climbing a nice very rocky hill and after returning I felt death wobble in the dirt low speed. I thought no way. Finished my run got on the road all was good hit a bump and there it was death wobble. found my track bar had come loose both ends. Believe alignment tech must have left it under torqued. Most part all good now. weird part now, first drive after being parked first right turn usually a little accelerating and a bump I feel the steering wheel wobble just a tiny bit goes away asap and after completely warmed up I can hit the same turn and nothing. Rancho track bar, metalcloak lower control arms, 2.5 lift. stock drag and tie rod. fox shocks and stabilizer. wrangler JL RUBICON 20K miles. I'm leaning towards track bar issue as my steering wheel doesn't sit centered anymore. but before I throw a new track bar metalcloak this time, I'm going to do another alignment and see what the machine tells me.
@Raydawg That very interesting. I think you are on the right track, but I would grab a friend and do the steering shimmy test before spending any more money. Maybe something else is loose?
I used to have a 2007 jeep JK. Chased down a death wobble for months. It ended up being the passenger side lower ball joint. Did the 12 to 6 oclock test with hands nothing. But then I stuck a long shovel underneath tire and pryed upward there was like 3mm of play. Replaced it. Wobble went away.
Another thing to point out that death wobble is an oscillation and generally happens when bigger wheels and tires are installed. More unsprung mass that a lot of the cheap shocks cant cope with. Ive seen good shocks like a bilstien completely remove death wobble. Many different things cause it i guess.
Whoah that opening part of the video! My jk has a slight vibration at 60 mph every time accelerating or decelerating when it passes that speed. Nothing even close to this video though.
@thomastrain7311 Yes, this JL is one of the worst cases we have ever seen! The change was night and day different at the end, though! No steering stabilizer and solid as a rock at any speed. We made sure to reinstall the stabilizer before sending it out though.
You know.... after analyzing the slow motion video, it makes me wonder if a change in engine/transmission mounts can mitigate the death wobble a bit. In any case, it is my firm belief that the wobble is entirely a resonant frequency thing like the Tacoma narrows bridge. Also like how a person's voice can literally shatter a wine glass. It sure seems like the engine/transmission is moving around at a frequency identical to the wheel wobble. Having tight parts eliminates the wobble to disallow it from getting set into motion in the first place, but the "problem" is that the natural resonant vibration frequency still exists. In theory, the heavier steering parts alone can change that frequency resonance so that the wobble is less likely to happen. What to do about it? I have no idea. I would like to see a mechanical engineer do a white paper on this phenomenon.
Also, the flex of the track bar seems to act as a spring that pushes the axle back exactly at the right frequency that matches the wobble. Simply beefing up that so it does not flex, and having stiffer rubber bushings / no rubber bushings can change that frequency resonance.
Hey Paul! We couldn't agree more that adding harder engine/transmission mounts would help reduce the resonance transmitted through the drivetrain. One drawback to that is the driving experience could be degraded because normal engine operation vibrations would be more easily transmitted to the driver's seat. And you're right about the flexing factory bar acting like a spring. We have had great success reducing and eliminating steering shimmy with our HD track bars, especially when using flex joint ends.
@@IronRockOffRoad I never found enjoyment in driving proverbial orbital sanders down the highway. My Jeep came with brown dog mounts and they are free to whoever wants them. We could go on all day about what could possibly cause this wobble and what can be done to alleviate it. Even bump steer could theoretically be what sends the wobble into motion.
@@paulstandaert5709 Orbital sanders, lol, I like that! Not sure what I would hate worse, driving an orbital sander or intermittant Death Wobble......I mean if you had the choice to pick one or the other. DW is never the choice, but luckily, it can be fixed. 🙂
@@IronRockOffRoad So is replacing worn out parts a band-aide or a cure? The more I think about what might cause death wobble the more I suspect that it is likely to be an unbalance rotating mass. If that is the case then replacing worn parts, while necessary, is only a temporary solution.
@KING4aday46 Did that fix the issue? Lots of people think death wobble only applies to Jeeps, but we are finding that any solid front axle vehicle can have the same problem.
This was very informative. I have a '75 Ramcharger that I put a steering stabilize on some 20 years ago because I did not understand how to properly deal with a constant shimmying when going down the road. It is time to walk through that check list on that truck. Also, I am convinced that half the reason for this video was to show off all your t-shirts. Cool to see you throwing Rock Auto some love too. (-:
Good eye! Yes, we believe the stock track bar is way too weak. Once we replaced it with our track bar and 1-ton steering we noticed a much more solid, planted feeling in the whole Jeep.
My 2 jeep/1Glladiator/1Wrangler SS using Falcon stearing stabilizer an no problem on any speed. Is running 55 to 102 miles por hour constantly any days.
Come on people, it's a simple toe adjustment. It's very touchy, but you can always dial it out. If your toed in at all, thats your problem. Turn your toe slightly out and try it. Keep doing it until the death wobble stops. It's that easy. Tires with big footprints can fight to go the same direction. They'll actually load up (bend the sidewall) if their not pointing in the same direction, and either slip , or load and skip. Aka, deathwobble. Camber angle affects tracking if the tires footprint isn't parallel to the axle. That being said, crown of the road affects actual camber, or footprint angle. So a slight road crown will make your front tires track towards each other. That being said, a slight toe out usually makes them track together. You cant measure, it's too touchy. You just have to toe it out slightly at a time till you find it. A hair too far and it'll come back. You can hide it by throwing parts at it but thats not the root. It should run straight with loose stuff.
Mike, while we agree that toe out of spec can be a cause of DW, it most certainly is not the only cause. If anything is loose, you MUST tighten it. If anything is work out, you MUST replace it. If anything is improperly adjusted, you MUST adjust to correct. If your tires are out of balance, you MUST balance them dynamically.
Great video. Question.. if i'm looking for a used wrangler. what's the best way to check for death wobble. Will it show up in a typical test drive.. Show up at a certain speed? Thanks so much. New subscriber !!
In your test drive, intentionally hit smaller bumps and/or potholes at differing speeds with both the left and right front tires at different times. This is not a sure fire way to get it to show up, but it certainly would bring out a bad case right away.
Jeeps are FAR more popular as far as modifications go. Many modifications change the geometry of the suspension and steering, and if those things are not addressed appropriately, driveability problems become more common. Not to mention, there are not many other vehicles with solid front axles anymore.
I have found its better to make a single change then test drive. Then make another. If you change everything at once and nothing changes, what didn't work?
We like that approach as well, especially if you're doing the work yourself. However, many shops will do their best to idenitfy all problems at once, and that's not a bad approach when you're paying them to do the work, because diagnostic (test drives) can take a lot of time that you're paying for.
The first thing you need to do is scrap those tires before you get busted for driving with bald tires. I'll bet the death wobble will be eliminated or greatly reduced. If not, check all the suspension parts like you did in the video. Replace the track bar bushings even if they show no signs of wear. They're cheap and easy to replace. Buy Moog suspension parts. They're the best. One thing that mechanics fail to inspect is if the steering gear box is bolted tight to the frame. I have a 2001 Jeep Grand Cherokee that had a serious death wobble. I replaced all the worn parts and replaced the track bar busings. It helped but did not eliminate the death wobble. I put the Jeep on ramps and had my son turn the steering wheel side to side. The suspension needs to be loaded in order to perform a proper suspension wear check. I heard a clunking noise, which came from the steering gear box being loose on the frame. I removed one bolt at a time from the gear box, cleaned it , lubed it with grease, then torqued it to 80 ft/lbs. Jeep uses a thread locker on their bolts that is extremely strong. Those bolts were tough to get out. If you check them for being tight, the thread locker will fool you into thinking they are tight, that's why you should remove them, clean them up, add lube, and re-torque to the manufacturer specs, minus 10% to allow for a lubed fastener. The death wobble completely disappeared and has never returned. It's been about 75,000 miles ago since I did this.
@dingznthingz We agree, the tires needed to be replaced. We recommended new tires to the owner and he replaced them. BUT we were able to eliminate the Death Wobble with these tires. We're glad to hear you performed your own Steering Shimmy Test to find your Death Wobble cause!
@bowstobourbon In the past we have found that moving the toe from toe-in to dead ahead reduces the tendency for death wobble. We learned these tips and tricks from chasing away death wobble for the last 20 years.

Great video...I have had a thrum in my 2019 JLUR since I drove it off the lot. Had it factory built and shipped so it did not have a chance to sit at all on the lot. Happens at around 60 - 66mph then go away at any other speeds. That thrum will change when it happens at certain speed ranges. It changes when I adjust the tire pressure up or down. Any ideas? The dealer has checked suspension and relaced the stabilizer just to do something but it did not work. They put on sahara tires and thrum was totally gone. I have the bfg ko2s stock size and all else is stock. I did have bfg replace the tires once and it still happend at different speed ranges at different pressures also so I think it's the tires. Any help is appreciated. Thanks
@mikeschmitt5273 We have heard of certain brands of tires being more prone to DW than others. Sometimes that's all it takes is just a different set of tires to fix the problem.
I’m purchasing a Jeep this week and want to know everything. My friend has a Jeep and it appears this is a common issue. I’m new to this but could improper lift kit be a cause?
@Bulldog-mi3om Thanks for reaching out. An improper lift kit, meaning an improperly set up lift kit or improperly adjusted lift kit could contribute to death wobble, yes. All of our lift kits are designed and built in-house, and our instructions are written from an actual installation of our kit. You can be confident that an Iron Rock kit is going to work right from the beginning. We adjust each component in our kits to as close to perfect as we can get them then put those measurements in our instructions. If you have any questions, please give us a call and talk to a real person 952-210-7185. Or send us an email: contactus@ironrockoffroad.com, tech@ironrockoffroad.com
How about caster indexing washers? I didn’t want to shell out a bunch of money for adjustable control arms just yet. Hard to find anything about adjusting caster with indexing washers and I just got mine in today and would love some pointers!
@umustbbornagainActs2-38 caster indexing washers can also work to get your Jeep the adjustment you want. Thanks for calling them out. We sell some for other Jeep models, but not for the JL/JT.
Is putting 30 psi going to trip the TPMS indicator on the DIC? I know mine if it drops below 31 psi it activates the tpms Low air indicator? Just curious
@jasonalward4720 It depends on the year of the Jeep. If you have a JL, we have seen this happen. Most of our JL customers have already purchased a device to reset their speedometer for larger tires and the same device can also adjust the setting for the TPMS indicator. We like the Tazer to adjust these settings: www.ironrockoffroad.com/product/tazer-jl-mini.html?Category_Code=
I own a 2008 Jeep Wrangler and it had a death wobble when I purchased it after changing the tires and having them rebalance the death wobble went away and haven't had it since been almost 5 years
How do you not know your steering box is not bad? I have about a 1/4 steering turn before the wheels respond, and the Jeep is seriously twitchy and runs all over the road with road defects and wind. I have a brand new stabilizer, and it really depends on the stabilizer. One I had lasted 5 years where, whereas others last 6 months. The stabilizer is great for bump steer, but tracking the jeep is unnecessary. I have driven big, tired, older trucks, and they never had stabilizers but would track with road imperfections.
@OldGuyAdventure Thanks for the feedback. We made this video trying to help as many people as we could so some of the information might seem more obvious to someone with a little more hands-on experience.

@@pjfan173 Absolutely! We offer an affordable 2" lift kit that will keep your OEM shocks. Made in the USA! www.ironrockoffroad.com/product/Gladiator-2-lift-kit.html
@@pjfan173 Don't worry about never going off road! These Jeeps are super cool no matter where they go! To be honest, a lot of Jeeps see 99% road and go off road once a year.
@maribabette2205 No, not all Jeeps do this. There are lots of Jeeps on the road that have never had this issue. Many times, it is due to lack of basic, regular maintenance. My Jeep is over 20 years old, and it has only happened to me once, and that was my fault. 😁 I got lazy and didn't replace some worn out front suspension parts. If you take care of your Jeep, it will take care of you!

Dealing with this on my girlfriends 2015 Wrangler with a small lift the aftermarket Pitman arm is actually wallowed out at the splines, the wobble got severe enough to bind up the aftermarket dual steering stabilizer and dent the stabilizer bodies and also noticed that the tires have broken belts in them, I’ll be fixing all of this and correcting the alignment we run auto repair business and I fix a lot of stuff like this I will say this I don’t care what wheel weights are on your setup almost every single time I’ve taken somebody else’s balance job and put it on our machine it is shown to be off so don’t take having weights on your wheels as a sign that they are balanced correctly fyi
@DSRE535 Good advice on the wheel weights! At a minimum we recommend dynamically balancing your tires. What type of balancing do you do at your auto repair business?
@@IronRockOffRoad thanks, i dynamically balance everything using our Hunter tire balancer, which I can also do centering checks to make sure you don’t have any bent wheels as well, this is a nice feature to have especially when you have something with Bigger Tires!
@@IronRockOffRoad also something to watch out for is putting 10 ply LT truck tires designed for big heavy diesel pick ups 3/4-1-ton Is probably not the greatest idea for something you’re driving on the street 95% of the time not only are they way heavier and harder on Parts but It can make a vehicle really ride like a rock it’s just something to keep an eye out for because most of the aftermarket tires in the common off-road sizes are E-load range It’s all about the combination of parts everything needs to work together, Maintenance becomes much more frequent with aftermarket parts as well!
@DSRE535 Great point on the E load tires. Most people don't even notice that and then wonder why their vehicle rides like a dump truck. Do you have a favorite tire brand? Or one that you recommend?
@@IronRockOffRoad so like the vehicle that I just dealt with 2015 Wrangler with a Ruff country 2.5 inch lift that was already done a couple years ago It has a 315/70/17 tire on it and the only somewhat affordable tire that I could find that was less than an E range was a Mickey Thompson Baja legend EXP and so far at 30 psi they actually ride really nice very quiet for a big tire but they are still a load range D there just isn’t very many options it’s just something you have to watch out for
@kolob316 We installed our JL/JT 1-Ton steering kit and a new solid track bar with Flex Joints. 1-Ton Steering: www.ironrockoffroad.com/product/jljt-rubicon-1-ton-steering-kit.html Track Bar: www.ironrockoffroad.com/product/jljt-front-adjustable-track-bar-kit.html
Death wobble in the jeeps is caused by incorrect toe in. Get a set of alignment plates and set it at 1/8" toe in and it will go away. When you take it to a alignment shop, they will put it into the green zone on the screen and call it good, which it is not unless they happen to land on at 1/8" toe in
@johnrodriguez473 We agree, incorrect toe-in can contribute to death wobble but it may not be the only issue causing it. Toe adjustment is easy to do yourself on a solid axle vehicle like a Jeep using our alignment tools, no need to go to the alignment shop at all. Toe adjustment is one of many factors that can cause death wobble. We have seen death wobble get better by adjusting Toe to zero or even slight Toe-out. Again, it is almost always more than one issue contributing to death wobble. You have to consider and inspect every piece in the system before you determine the cause.
Good eye Jarred, yes, the most accurate alignment measurements would be done under the full weight of the vehicle. We should have mentioned that in the video. Thank you!
@@IronRockOffRoad you're welcome. I just wanted to make while I'm working on this death wobble on this 2012, that I get the most accurate. However with them having straight axles and not independent suspension like most other vehicles, it probably won't make too big of a difference. But obviously obviously it's best lol
Good eye. We noticed that when it came in. Maybe it shook itself loose? We checked the fluid and made sure it was hooked up before it went back to our customer.
It's actually sad brand new vehicles still get the death wobble under 20k, 40 years of death wobble. And technology to correct it. But choose not to. 😊pile of garbage costs 30-100k I had an 04 dodge that had the death wobble replaced every single part on the front end stabilizers, shocks, control arms track bar ect ect. After 3 years of driving it started again. So I figured if I made an axle truss and completely changed the geometry and configuration of the control arms to eliminate alot of lateral movement, eliminating the track bar all together. Best thing I ever did to that pile of dodge, My dad couldn't believe the ride going 75 mph on a wash board dirt road. drove like a Cadillac. Unfortunately my physcotic ex ripped the doors off the hinges,
That beginning video looks like the engine and transmission mounts are loose or broke. On another note I had jeep maxed big tires massive lift etc. Jeep next to me on the interstate and he drifted into my lane trying to stop the wobble. I due have issues with "Mall Terrain" vehicles and the safety of other people when owners are irresponsible.
@nickylowe4381 That's crazy! I would go through the death wobble checklist and see what you find. Afterward I would take your Jeep to a trusted shop and let them go through the same checklist and compare your results. If you still need help, give us a call! You will talk to a real person, and we'll help you get it figured out! 952-210-7185 Death Wobble Checklist: www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf
I'm not sure i agree with you on the tire PSI the PSI on the door label is for the factory tires and each tire size and manufacturer has there PSI raiding IF you install a larger tire that requires a certain PSI for that tire and you under flight or over Will void the warranty I always go by the tire But i could be wrong
That is a common story that we hear from our customers. That is part of the reason we developed our toe alignment tools. The alignment tools are cheaper than a professional alignment job and that is usually the only thing a professional alignment shop will adjust on a Jeep. www.ironrockoffroad.com/product/wheel-alignment-tool.html
@IronRockOffRoad i spoke with 4 wheel parts and they said they can do an "adjust everything adjustable alignment" for 300 something bucks. Seeing how that's a ton of work it might be worth it but it dang sure better be right on the money whenb they are done
@autotek7930 yes, it is more work than a factory alignment, so it will typically cost more to have a shop do it. But you're right, that's a good chunk of change, so hold them to making sure it's right.
It can be frustrating, no doubt. Not knowing how is not the end of the world though. Even 4x4 shops and alignment techs can benefit from the info in this video and from using our steering shimmy checklist.
@lekendrickkelly6077 Check out our death wobble checklist: www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf I would also encourage you to watch the death wobble video all the way through and apply the steps shown.
Be aware im NOT an expert but this is not some witchcraft. I see this car has wheel spacers.. after checking everything in the front suspension try test drive the car without them, and a other set of tires if possible. Running much negative offset on the tires make the steering very sensitive to unbalance in wheels and worn out parts. Lift the car up and lower it to rest on it's axles on a WERY sturdy pile of wooden blocks. Start the car and run it up to speed at least to the speed where the wobble exist. At the same time watch the tires for vibration, not being circular, not warped etc.. Then you wil really find out if you have a set of balanced tires on exactly YOUR car with that set, maybe your spacers are badly machined etc. Wide rims and spacers that give mutch negative wheel offset witch mess up your scrub radius that is known for causing wobble issues. What i been told is lower your caster close to the minimum spec and the toe in close to the lower specs from the car manufacturer if you run tires with very negative offset. Of course upgrading the steering system will also help like it's done in this video. If you really want the wide look and tires outside the fenders the best option is to upgrade to a wider axle but that is obviously not a cheap route..
There is a threshhold (I think it's 32psi?? - please correct me TPMS experts 🙂) if you stay above the dash light will remain off. If you go below that, you will have to reset them by going back up to a certain pressure (37psi?? again please correct me if I'm wrong). Alternatively, there are products on the market that can turn that light off permanently if you are wanting to run a lower pressure or if you decided you don't want to use TPMS sensors. I use the zautomotive.com Tazer. It has a lot of great features for the price.
I have had 5 jeeps, YJs, TJs and even in MJ. They all had the death wobble in various forms. This is probably the best discussion of the issue. It is a beast to track down.
It can be tricky sometimes. But the good thing is it does not have to be permanent. Every case can be solved by identifying and fixing the cause.
Don’t mean to throw shade on your comment but I had a YJ and never had death wobble. How do you have death wobble with leaf springs?
@@Saturnian4417 Death Wobble can result from many things. Worn steering parts, bad alignment, unbalanced tires, etc.
@@IronRockOffRoad agreed. I owned a YJ and several friends owned YJ’s too and no one ever complained of death wobble with leaf springs. I don’t think it’s possible unless the shackles or u bolts on the perches are loose
@@Saturnian4417 You never know. If someone did get DW with leaf springs I wouldn't be too surprised. I do know we would try our best to help a YJ owner get to the bottom of the issue though.
Ball joints can also contribute to the problem. I went through all of your checklist items on my 2017 Rubicon and still had a wobble. New tires, alignment, 1 ton tie rod ends, Teraflex oversized track bar, etc. all made improvements, but never totally fixed the wobble.
Changing the ball joints to the Teraflex adjustable ball joints made it rock solid. I don't know how that can be the problem, even the alignment shop said ball joints would not cause death wobble, but it was. And all that we could see was slight play on the driver side lower ball joint. It drives perfectly now.
I would add it to the checklist.
Ahh, thank you, If you look on page 2 of the checklist, we do have you check your ball joints 🙂 www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf
That is good. I didn't notice it in the video. Thanks! @@IronRockOffRoad
@@commonsense6050 Thanks for watching! If this video helped you, share it with others 🙂
Look on line, many jeeps with stock wheels and less than 500 miles are expieriencing this issue including my wifes 2022 with 12000k. More to come on this issue. So far Chrisler has ignored the issue. No recall to date.
thanks for your video. My wife's JT had death wobble. Not bad, but enough to make it un-nerving. Read up a multiple other pages and watch a few videos about death wobble. Upgraded a couple steering parts ( drag link, trackbar that was planned to be upgraded this summer anyway). Did everything on the other's pages list (Tightened everything, removed one piece at a time and checked the bushings, checked the shocks, tire pressure..... with no change. Watched your video and the checklist. You talked about and provided numbers about tow. Down to my last straw and doubting it would work.... I took two pieces of angle iron and rubber clamps to clamp the angle iron to the rotors. Leveled the angle iron to the ground, plum bob from the center of the hub down to the angle iron to mark the center, then measured out a foot both ways. Measured across and found it towed in 1/8". Adjusted to 1/32". Death wobble gone. (Honestly, I doubted it would fix the issue and was surprised) . It's been two months with no signs of it. My wife is happy, So I'm happy.
@delbancroft9339 That is awesome! Glad we were able to help!
I used to work in a shop that specialized in suspension and alignments. 90% of the time death wobble is caused by a bad trac bar, loose trac bar bolts, or incorrect castor settings. Ignore the factory castor settings if your rig is lifted and has bigger tires, as the effective castor angle changes as the distance from the ball joints to the ground changes. A steering dampner can not cause or repair death wobble, regardless of how many techs tell you it can. A dampner can only mask a problem, not create one, unless it is physically damaged and binding up. Dealerships specialize in replacing parts, not fixing problems. I can not count how many Jeeps I've had to fix after it left the dealer with a new steering stabilizer, but still had death wobble.
Thanks for sharing your past experience! You're right, there are many possible causes, and some tend to be more common than others.
Agreed

This video reminded me...
The other day I was looking on your website for something I thought I remembered you sold, but I couldn't find it.
Track bar oversize bolt and nut insert kit thingy for a Jeep WJ.
Have you still got a part number for this item?
What’s the normal cost to replace a trac bar?
@@monicarossow6052 It can vary depending on the model you're working on, but typically between 200-300.

@dawoodk103 Thank you for the feedback! We're just looking to spread the knowledge we've learned from the last 20 years of building Jeep parts.
Great info. Thanks so much. Lesson here is if you don’t know what you’re doing, take it to a shop that does and listen to what they say and if it’s a good shop, replace what they tell you needs to be replaced. Again awesome video.
Great tip!
so many people go straight to the Steering Stabilizer as the cause, because they do not want to take the time and effort to track down the real cause.
You did a great job at explaining the procedure of tracking down and by offering a check list.
@TwoFeatherChannel Exactly! Thank you for the feedback!
In my case the steering stabilizer did start to leak. Which i believe is the root cause of my death wobble on my jeep. But will be replacing the whole steering kit together to make sure
@@zer0luink I don't think it is. some people take their steering stabilizer off completely and run with out one.
most of the time it is a wearable part such as a bushing, worn out bolt holes and joints.
Ball Joints, Tie Rod Ends, Track Bar Bushings and the Brackets they bolt to.
a new steering stabilizer is a Band-Aid, it appears to solve the problem but it only covers up the problem and ruins the stabilizer later on.
Excellent video. Thank you for all the accurate information and all the work to create this.
@wutranclan4266 Thank you for the complement!
Had my jeep for 22 years. Death wobble was a issue about 10 years of owning it. Replaced all the bushing on the front end of the Jeep. Control arms etc... from rubber to polyurathane and not only did it fix the issue but I have not had death wobble since. 2001 TJ.
Glad to hear it. Bushings are often overlooked when troubleshooting death wobble.
Fantastic video. My 22 ecodiesel gladiator had it. Replaced the steering stabilizer stopped for a bit but still haad shimmy. 20k later its back
@gmac9956 Unfortunately, that is a story we hear often. The stabilizer is certainly doing something to mitigate the death wobble, but it isn't the solution. We always recommend going through the entire DW checklist to be certain everything is good, but on the JL & JT we frequently see the joint at the pitman arm fail. We created an OEM replacement joint for that spot that is much bigger and stronger. It is a much less expensive option than a completely new steering system and can easily be done in the driveway with common hand tools.

Probably the best video I’ve seen to help with death wobble. Very helpful and thank you!
Thank you! We worked really hard to put this together and make it as thorough as possible. Glad it helped!
Do note, fully extended the damper. They tend to have dead spots after full extension. Also the damper absolutely has been an issue many times. They basically turn into a spring when bad. The big thing I see is customers, and a lot of techs don’t know the difference between death wobble, and a minor steering shimmy. The shimmy is almost always the damper, and Dosent occur when removed. The death wobble is almost never the damper
The Jeep we were working on in this video had a good stabilizer. When it was installed, the shimmy was less than when we took it out. Then we went through our checklist and were able to make the jeep drive solid, without a stabilizer installed.
Very interesting, I like your methodological way of addressing the issue and thanks for allowing us access to the checklist!! Great job!!
Thank you, glad you enjoyed it. Better yet, we hope you found it useful.
@@IronRockOffRoad very much so, thanks
In my opinion 4 degrees of caster is not enough, you will get a twitchy steering wheel. I find the perfect amount to be 6 degrees on a 3 inch lift.
Caster settings can vary pretty widely depending on the model and lift height. Some models seem to want less caster and some want more.
I'm at 8deg + on a 6" lift heavy diesel JT. The lift manufacturer wanted 6.5deg at 3.5" lift. A bit of tuning finds the right amount. It's not as much of a factor in death wobble. The JT and JL Wrangers are really sensitive to wheel balance. In addition, the front drag link and track bar as factory units wear very quickly with any amount of lift and offroading schedule. Just replace them with 1 Ton options. Mine were very loose at 9k miles.
@@iamblaineful yes, thank you for pointing out that sometimes a bit of tuning may be needed. Lift manufacturers do their due diligence to offer a good starting point for alignments, however, people set up their Jeeps in an infinite number of ways so it's impossible to say an exact number will work with all Jeeps.
I have used iron rock off-road products for Uber 5 years to defeat death wobble you can stabilize your steering box with their products you can stop your tie rod from flexing these products are top-notch and I would highly recommend for an XJ with death wobble the heavy duty solid steel tie rod.
@thedeathwobblechannel6539 Thank you!
Excellent Video! Thank You! I am not having the death wobble often, but it does happen when I hit a bad part of the road every now and again. I do have a lot of upgrades, full King Coil-Overs, large over-sized tie rod, track bar, drag link and large polygon upper and lower control arms. Not sure about the links and I believe my pitman arm is a stocker. I am at max tires with 40's on 20' KMS Grenade bead-locks. Wish I could show you a picture. Anyways, I did download the checklist and will be going through the steps as I don't want the wobble to happen when my daughter drive the Jeep. BTW, it is a 2020 Rubicon / Recon. Like I said, I don't get the wobble very often and I make the drive from S Florida to upper Michigan at least once a year to hit trails with my 5 brothers and da; we all have Jeeps.

@bobbyclayton7348 The Death Wobble checklist is a big help. Your setup sounds good to me. Let us know if we can help with anything!
Thank you for your very thorough explanation and inspection. I've learned a lot in this video
@America_took_my_zebra_stripes Glad it was helpful!
Great video, that said, I would have liked you to repair/replace one item at a time ( starting with tire rotation) to see if one item was the cause of the death wobble. Understanding that it may have been more than one item.
Because we know that any looseness or imbalance can cause steering shimmy, we went ahead and fixed all known issues right away. But we agree, that would have been a fun test, if nothing else, to see what changes in the shimmy (severity, speed) based on each single change.
I had a serious Death Wobble in my 2021 Deisel JL. The wobble started at about 4,500 miles. We had to replace almost every major part in the front end before we got rid of the wobble. The only thing we didn't have to replace were the ball joints. I am at 27,000 miles now and still watch it closely in case it returns.
Glad you were able to get it taken care of! Good Job!
how much did it cost to replace the front parts?
It was all done on warranty. It took about 8 visits to get it right.@@quincy189

@LetTheJourneyBegin Glad to hear it! Sometimes it's a just a simple adjustment that needs to be made.
Can you just use adjustable lowers and not change uppers? Ball joints and adjustable CAs are phase 2 if phase 1 (drag link, TREs, new tires and alignment) doesn’t work.
@@JP-eb3oz You can use adjustable lower control arms by themselves if you need to.
What do you do when the death wobble is on a brand new Jeep like mine. I purchased a brand new 2019 Jeep JL Rubicon Unlimited It started to death wobble 2 weeks after I purchased it with less the 400 miles on it. It was so new that the dealer had no parts to fix it. After a month or so they put a new steering damper on it. It lasted maybe 2000 miles and death wobbled again, any way it is on it's 4th damper and the Jeep only has 16000 miles on it and starting to get that feeling again. Jeep refuses to replace the aluminum steering box because they claim it's not the problem. I have a Jeep that I don't trust and one my wife refuses to drive and no help from Jeep. I have a 7 year 70K bumper to bumper warranty which does no good if they can't fix the death wobble. I feel that I shouldn't have to spend thousands of dollars to repair a Jeep that was not right from the factory. But I will end up taking it the shorts to sell or trade it. Next vehicle will be a Toyota 4Runner TRD pro.
It's unfortunate many dealers are incompetent what it comes to suspension and steering diagnosis and repair. However many dealers have excellent technicians who are very knowledgeable and able to help you. Stand your your ground when you bring it in, stating that the condition recurs even after multiple attempts at throwing a steering stabilizer at it. Our guess is that some other loose/worn/improperly adjusted or balanced part(s) are attributing to the problem, and prematurely overstressing your stabilizer to the point of failure. Insist that they watch this video and complete the tests within our steering shimmy checklist: www.ironrockoffroad.com/Merchant2/DeathWobbleChecklist.pdf
I have a 95 series 80 Landcruiser 3” lift running 33” tires with close to 400,000 miles and have never had DW. However, bought a new jeep for my daughter…hence why I’m reading all your comments. I bought a new bronco for my other daughter…NO Problems 😮

You guys are goated! I wish I would've found you guys sooner when I bought my WJ
@theadventuringcoonclan1942 Thank you for the complement! We're still coming out with new products for the WJ so keep us in mind for your next upgrade!
4 degrees of + caster is way too low, IMO. A slight toe out helps to mitigate DW. That's per the engineers at Steer Smarts. A sector shaft brace, like the one from Metalcloak, is highly recommended.
A common issue is that a steering stabilizer will mask DW until it's worn out from being overworked. As you mentioned in your process, a properly setup vehicle will drive with no DW with the stabilizer removed, but it's an easy and cheap bandaid for dealerships. Finally, or perhaps foremost, get a good torque wrench and go over everything when you get home from the dealership. Too many Jeeps are delivered with loose steering box bolts, loose Pitman arm nuts, loose control arm bolts, loose ball joints, and more. It's like they don't even own a torque wrench in Toledo. It's scary the stuff they let go.
Thanks for your feedback. Depending on the Jeep, lift height, and other accompanying modifications, a wide range of caster could be used. Reducing caster in most cases does reduce steering shimmy. We produced our death wobble checklist over 15 years ago, and have always maintained that a slight tow out can help with steering shimmy. If other manufacturers are agreeing, that solidifies our recommendation. We can't agree with you more about double checking torque on all your suspension and steering fasteners. That is good practice whether you are experiencing an issue or not. Especially 200-500 miles after an initial installation, and after any moderate to heavy or high speed off road driving.

@@IronRockOffRoad I got tires balanced, replaced tierod, tackbar, drag link, replaced upper and lower control arms. I’m planning doing the upper and lower ball joints.
The dramatic wiggle is still there.
I’ll continue to go through the list, but any other encouraging suggestions during the process?
@Re-DeclarationOfIndependence You are on the right track! Don't forget to check your toe alignment and wheel bearings. Most of us Jeep guys are running bigger, heavier tires that put added stress on wheel bearings. If there is any play in them, a bigger tire will be able to wander and put the toe alignment out of spec. Luckily, on a solid axle vehicle like a Jeep it is easy to check and adjust the toe setting at home.
Wheel alignment tool:
www.ironrockoffroad.com/product/wheel-alignment-tool.html
None of the manufacturers put stiff enough track bar, drag link and tie rods in live axle vehicles. Replace all three with heavy duty components and you don't need a steering stabilizer. Stabilizers just mask the problems until they get to a point where the problems are too big to mask.
The steering stabilizer still is an important part of your steering system. We agree, most people don't understand what the steering stabilizer is for and assume it is the fix. Check out our video on steering stabilizers:
ruclips.net/video/2giiC8Oruh8/видео.html
Awesome video wish you were my mechanic. Dealerships don't want to put in the time to fix your issues
Sadly, you're right. A good offroad shop may be a better choice for suspension and steering problems like this.
What about them negative offset wheels with bigger, heavier tires in conjunction with the wheel spacers ..they push the wheels out and multiply the stress on the steering components, especially the tie rod and ends.
@MrTurbo64 you're absolutely right about the compounded stresses added with these types of additions. In many cases, it's a necessary compromise when the vehicle owner wants to run larger tires without clearance problems. The good thing is, we have developed steering systems with larger, and more heavy duty tie rod ends and linkages, that drastically improve longevity in those components in a higher stress environment. Many don't realize the facts you brought up and how they can affect other vehicle components. We are here to answer any questions you may have when doing your build.
2019 Wrangler with death wobble. Dealerships saying it’s the steering stabilizer. Been through two stabilizers in 2,000 miles! What’s the root cause of this? Welding issues?
@SeizetheAuraRosaliesRareHe-p1d The steering stabilizer gets the blame a lot on the newer Jeeps. We were told the same thing by our local dealership and had it replaced a couple times. I'd recommend going through our death wobble checklist or giving the checklist to a reputable mechanic that you trust. On the 2019 and newer Jeep Wrangler and Gladiator we have often times found the steering joint at the pitman arm to be loose as well as the track bar joints. These parts wear out prematurely.

Great video and great description of your troubleshooting process and fixes. Thanks.
@michaelbyers3094 Glad it helped! Thanks for watching!
I learned something new about the PSI. I didn’t know that going about 40 is too high a pressure 😮
Glad we could help!
I have a weird one, Off road climbing a nice very rocky hill and after returning I felt death wobble in the dirt low speed. I thought no way. Finished my run got on the road all was good hit a bump and there it was death wobble. found my track bar had come loose both ends. Believe alignment tech must have left it under torqued. Most part all good now. weird part now, first drive after being parked first right turn usually a little accelerating and a bump I feel the steering wheel wobble just a tiny bit goes away asap and after completely warmed up I can hit the same turn and nothing. Rancho track bar, metalcloak lower control arms, 2.5 lift. stock drag and tie rod. fox shocks and stabilizer. wrangler JL RUBICON 20K miles. I'm leaning towards track bar issue as my steering wheel doesn't sit centered anymore. but before I throw a new track bar metalcloak this time, I'm going to do another alignment and see what the machine tells me.
@Raydawg That very interesting. I think you are on the right track, but I would grab a friend and do the steering shimmy test before spending any more money. Maybe something else is loose?
I used to have a 2007 jeep JK. Chased down a death wobble for months. It ended up being the passenger side lower ball joint. Did the 12 to 6 oclock test with hands nothing. But then I stuck a long shovel underneath tire and pryed upward there was like 3mm of play. Replaced it. Wobble went away.
@tribulation138 Great to hear a success story!
Another thing to point out that death wobble is an oscillation and generally happens when bigger wheels and tires are installed. More unsprung mass that a lot of the cheap shocks cant cope with. Ive seen good shocks like a bilstien completely remove death wobble. Many different things cause it i guess.
@440capnhook It is true, Death Wobble can be caused by a lot of different things.
My TJ has never did this. 120k Good video, thanks!
@kcbroncohater Glad to hear! Thanks for watching!
Whoah that opening part of the video! My jk has a slight vibration at 60 mph every time accelerating or decelerating when it passes that speed. Nothing even close to this video though.
@thomastrain7311 Yes, this JL is one of the worst cases we have ever seen! The change was night and day different at the end, though! No steering stabilizer and solid as a rock at any speed. We made sure to reinstall the stabilizer before sending it out though.
You know.... after analyzing the slow motion video, it makes me wonder if a change in engine/transmission mounts can mitigate the death wobble a bit. In any case, it is my firm belief that the wobble is entirely a resonant frequency thing like the Tacoma narrows bridge. Also like how a person's voice can literally shatter a wine glass. It sure seems like the engine/transmission is moving around at a frequency identical to the wheel wobble.
Having tight parts eliminates the wobble to disallow it from getting set into motion in the first place, but the "problem" is that the natural resonant vibration frequency still exists. In theory, the heavier steering parts alone can change that frequency resonance so that the wobble is less likely to happen.
What to do about it? I have no idea. I would like to see a mechanical engineer do a white paper on this phenomenon.
Also, the flex of the track bar seems to act as a spring that pushes the axle back exactly at the right frequency that matches the wobble. Simply beefing up that so it does not flex, and having stiffer rubber bushings / no rubber bushings can change that frequency resonance.
Hey Paul! We couldn't agree more that adding harder engine/transmission mounts would help reduce the resonance transmitted through the drivetrain. One drawback to that is the driving experience could be degraded because normal engine operation vibrations would be more easily transmitted to the driver's seat. And you're right about the flexing factory bar acting like a spring. We have had great success reducing and eliminating steering shimmy with our HD track bars, especially when using flex joint ends.
@@IronRockOffRoad I never found enjoyment in driving proverbial orbital sanders down the highway. My Jeep came with brown dog mounts and they are free to whoever wants them.
We could go on all day about what could possibly cause this wobble and what can be done to alleviate it. Even bump steer could theoretically be what sends the wobble into motion.
@@paulstandaert5709 Orbital sanders, lol, I like that! Not sure what I would hate worse, driving an orbital sander or intermittant Death Wobble......I mean if you had the choice to pick one or the other. DW is never the choice, but luckily, it can be fixed. 🙂
@@IronRockOffRoad So is replacing worn out parts a band-aide or a cure? The more I think about what might cause death wobble the more I suspect that it is likely to be an unbalance rotating mass. If that is the case then replacing worn parts, while necessary, is only a temporary solution.
I had this wiggle on my Suzuki samurai. It was the steering stabilizer shock. It would start around 30 mph.
@KING4aday46 Did that fix the issue? Lots of people think death wobble only applies to Jeeps, but we are finding that any solid front axle vehicle can have the same problem.
@@IronRockOffRoad it fixed the issue. 4 wheel drive Suzuki samurai 1989.
@KING4aday4 Glad to hear you got it fixed! I love those Suzuki Samurais!
This was very informative. I have a '75 Ramcharger that I put a steering stabilize on some 20 years ago because I did not understand how to properly deal with a constant shimmying when going down the road. It is time to walk through that check list on that truck. Also, I am convinced that half the reason for this video was to show off all your t-shirts. Cool to see you throwing Rock Auto some love too.

Thank you, we hope you and many others can be helped by the info we provide.
At the very end of this video it showed death wobble in slow motion. It looked like the stock trackbar was bowing a little.
Good eye! Yes, we believe the stock track bar is way too weak. Once we replaced it with our track bar and 1-ton steering we noticed a much more solid, planted feeling in the whole Jeep.

@gabrielnazario3581 Glad to hear you haven't experienced Death Wobble!
Come on people, it's a simple toe adjustment.
It's very touchy, but you can always dial it out.
If your toed in at all, thats your problem.
Turn your toe slightly out and try it.
Keep doing it until the death wobble stops.
It's that easy.
Tires with big footprints can fight to go the same direction.
They'll actually load up (bend the sidewall) if their not pointing in the same direction, and either slip , or load and skip. Aka, deathwobble.
Camber angle affects tracking if the tires footprint isn't parallel to the axle.
That being said, crown of the road affects actual camber, or footprint angle.
So a slight road crown will make your front tires track towards each other.
That being said, a slight toe out usually makes them track together.
You cant measure, it's too touchy.
You just have to toe it out slightly at a time till you find it.
A hair too far and it'll come back.
You can hide it by throwing parts at it but thats not the root.
It should run straight with loose stuff.
Mike, while we agree that toe out of spec can be a cause of DW, it most certainly is not the only cause. If anything is loose, you MUST tighten it. If anything is work out, you MUST replace it. If anything is improperly adjusted, you MUST adjust to correct. If your tires are out of balance, you MUST balance them dynamically.
Great video. Question.. if i'm looking for a used wrangler. what's the best way to check for death wobble. Will it show up in a typical test drive.. Show up at a certain speed? Thanks so much. New subscriber !!
In your test drive, intentionally hit smaller bumps and/or potholes at differing speeds with both the left and right front tires at different times. This is not a sure fire way to get it to show up, but it certainly would bring out a bad case right away.
How is it this is a huge problem with jeeps but hardly heard of with other vehicles?
Jeeps are FAR more popular as far as modifications go. Many modifications change the geometry of the suspension and steering, and if those things are not addressed appropriately, driveability problems become more common. Not to mention, there are not many other vehicles with solid front axles anymore.
I have found its better to make a single change then test drive. Then make another. If you change everything at once and nothing changes, what didn't work?
We like that approach as well, especially if you're doing the work yourself. However, many shops will do their best to idenitfy all problems at once, and that's not a bad approach when you're paying them to do the work, because diagnostic (test drives) can take a lot of time that you're paying for.
The first thing you need to do is scrap those tires before you get busted for driving with bald tires. I'll bet the death wobble will be eliminated or greatly reduced. If not, check all the suspension parts like you did in the video. Replace the track bar bushings even if they show no signs of wear. They're cheap and easy to replace. Buy Moog suspension parts. They're the best. One thing that mechanics fail to inspect is if the steering gear box is bolted tight to the frame. I have a 2001 Jeep Grand Cherokee that had a serious death wobble. I replaced all the worn parts and replaced the track bar busings. It helped but did not eliminate the death wobble. I put the Jeep on ramps and had my son turn the steering wheel side to side. The suspension needs to be loaded in order to perform a proper suspension wear check. I heard a clunking noise, which came from the steering gear box being loose on the frame. I removed one bolt at a time from the gear box, cleaned it , lubed it with grease, then torqued it to 80 ft/lbs. Jeep uses a thread locker on their bolts that is extremely strong. Those bolts were tough to get out. If you check them for being tight, the thread locker will fool you into thinking they are tight, that's why you should remove them, clean them up, add lube, and re-torque to the manufacturer specs, minus 10% to allow for a lubed fastener. The death wobble completely disappeared and has never returned. It's been about 75,000 miles ago since I did this.
@dingznthingz We agree, the tires needed to be replaced. We recommended new tires to the owner and he replaced them. BUT we were able to eliminate the Death Wobble with these tires. We're glad to hear you performed your own Steering Shimmy Test to find your Death Wobble cause!
great vid, is there a reason you set the alignment to dead ahead to start?
@bowstobourbon In the past we have found that moving the toe from toe-in to dead ahead reduces the tendency for death wobble. We learned these tips and tricks from chasing away death wobble for the last 20 years.

Great video...I have had a thrum in my 2019 JLUR since I drove it off the lot. Had it factory built and shipped so it did not have a chance to sit at all on the lot. Happens at around 60 - 66mph then go away at any other speeds. That thrum will change when it happens at certain speed ranges. It changes when I adjust the tire pressure up or down. Any ideas? The dealer has checked suspension and relaced the stabilizer just to do something but it did not work. They put on sahara tires and thrum was totally gone. I have the bfg ko2s stock size and all else is stock. I did have bfg replace the tires once and it still happend at different speed ranges at different pressures also so I think it's the tires. Any help is appreciated. Thanks
@mikeschmitt5273 We have heard of certain brands of tires being more prone to DW than others. Sometimes that's all it takes is just a different set of tires to fix the problem.

Is putting 30 psi going to trip the TPMS indicator on the DIC? I know mine if it drops below 31 psi it activates the tpms Low air indicator? Just curious
@jasonalward4720 It depends on the year of the Jeep. If you have a JL, we have seen this happen. Most of our JL customers have already purchased a device to reset their speedometer for larger tires and the same device can also adjust the setting for the TPMS indicator.

I own a 2008 Jeep Wrangler and it had a death wobble when I purchased it after changing the tires and having them rebalance the death wobble went away and haven't had it since been almost 5 years
Sometimes the simple fix is all that is needed. I'm glad you didn't end up throwing a bunch of parts and money at the problem.
How do you not know your steering box is not bad? I have about a 1/4 steering turn before the wheels respond, and the Jeep is seriously twitchy and runs all over the road with road defects and wind. I have a brand new stabilizer, and it really depends on the stabilizer. One I had lasted 5 years where, whereas others last 6 months. The stabilizer is great for bump steer, but tracking the jeep is unnecessary. I have driven big, tired, older trucks, and they never had stabilizers but would track with road imperfections.

Dealing with this on my girlfriends 2015 Wrangler with a small lift the aftermarket Pitman arm is actually wallowed out at the splines, the wobble got severe enough to bind up the aftermarket dual steering stabilizer and dent the stabilizer bodies and also noticed that the tires have broken belts in them, I’ll be fixing all of this and correcting the alignment we run auto repair business and I fix a lot of stuff like this I will say this I don’t care what wheel weights are on your setup almost every single time I’ve taken somebody else’s balance job and put it on our machine it is shown to be off so don’t take having weights on your wheels as a sign that they are balanced correctly fyi
@DSRE535 Good advice on the wheel weights! At a minimum we recommend dynamically balancing your tires. What type of balancing do you do at your auto repair business?
@@IronRockOffRoad thanks, i dynamically balance everything using our Hunter tire balancer, which I can also do centering checks to make sure you don’t have any bent wheels as well, this is a nice feature to have especially when you have something with Bigger Tires!
@@IronRockOffRoad also something to watch out for is putting 10 ply LT truck tires designed for big heavy diesel pick ups 3/4-1-ton
Is probably not the greatest idea for something you’re driving on the street 95% of the time not only are they way heavier and harder on Parts but It can make a vehicle really ride like a rock it’s just something to keep an eye out for
because most of the aftermarket tires in the common off-road sizes are E-load range
It’s all about the combination of parts everything needs to work together, Maintenance becomes much more frequent with aftermarket parts as well!
@DSRE535 Great point on the E load tires. Most people don't even notice that and then wonder why their vehicle rides like a dump truck. Do you have a favorite tire brand? Or one that you recommend?
@@IronRockOffRoad so like the vehicle that I just dealt with 2015 Wrangler with a Ruff country 2.5 inch lift that was already done a couple years ago It has a 315/70/17 tire on it and the only somewhat affordable tire that I could find that was less than an E range was a Mickey Thompson Baja legend EXP and so far at 30 psi they actually ride really nice very quiet for a big tire but they are still a load range D there just isn’t very many options it’s just something you have to watch out for

Death wobble in the jeeps is caused by incorrect toe in. Get a set of alignment plates and set it at 1/8" toe in and it will go away. When you take it to a alignment shop, they will put it into the green zone on the screen and call it good, which it is not unless they happen to land on at 1/8" toe in
@johnrodriguez473 We agree, incorrect toe-in can contribute to death wobble but it may not be the only issue causing it. Toe adjustment is easy to do yourself on a solid axle vehicle like a Jeep using our alignment tools, no need to go to the alignment shop at all. Toe adjustment is one of many factors that can cause death wobble. We have seen death wobble get better by adjusting Toe to zero or even slight Toe-out. Again, it is almost always more than one issue contributing to death wobble. You have to consider and inspect every piece in the system before you determine the cause.
Don't you need to have the vehicle on its own weight when adjusting the alignment?
Good eye Jarred, yes, the most accurate alignment measurements would be done under the full weight of the vehicle. We should have mentioned that in the video. Thank you!
@@IronRockOffRoad you're welcome. I just wanted to make while I'm working on this death wobble on this 2012, that I get the most accurate. However with them having straight axles and not independent suspension like most other vehicles, it probably won't make too big of a difference. But obviously obviously it's best lol
Your tires look like slicks homie
@justinneedham1791 Agreed! We told the customer to get new tires and he did right after this video.
I am new to the Jeep thing. Is the death wobble mostly a problem when you have big tires like the one in the video?
It seems to be far more common in modified vehicles, but it can happen on completely stock vehicles as well.
In the last clip it looked like the differential vent tube wasn't hooked up to the differential. No Buenos for the gears
Good eye. We noticed that when it came in. Maybe it shook itself loose? We checked the fluid and made sure it was hooked up before it went back to our customer.
It's actually sad brand new vehicles still get the death wobble under 20k, 40 years of death wobble. And technology to correct it. But choose not to. 😊pile of garbage costs 30-100k I had an 04 dodge that had the death wobble replaced every single part on the front end stabilizers, shocks, control arms track bar ect ect. After 3 years of driving it started again. So I figured if I made an axle truss and completely changed the geometry and configuration of the control arms to eliminate alot of lateral movement, eliminating the track bar all together. Best thing I ever did to that pile of dodge, My dad couldn't believe the ride going 75 mph on a wash board dirt road. drove like a Cadillac.

It depends how long you've been watching!
I'm not sure i agree with you on the tire PSI the PSI on the door label is for the factory tires and each tire size and manufacturer has there PSI raiding IF you install a larger tire that requires a certain PSI for that tire and you under flight or over Will void the warranty I always go by the tire But i could be wrong
@deandye3255 The tire pressure can vary depending on the load range of the tire and the weight of the vehicle it is installed onto.
I'm having troubles finding a worthy alignment shop here in El paso Texas. I'm not finding many trustworthy places to get stuff done
That is a common story that we hear from our customers. That is part of the reason we developed our toe alignment tools. The alignment tools are cheaper than a professional alignment job and that is usually the only thing a professional alignment shop will adjust on a Jeep.

@IronRockOffRoad i spoke with 4 wheel parts and they said they can do an "adjust everything adjustable alignment" for 300 something bucks. Seeing how that's a ton of work it might be worth it but it dang sure better be right on the money whenb they are done
@autotek7930 yes, it is more work than a factory alignment, so it will typically cost more to have a shop do it. But you're right, that's a good chunk of change, so hold them to making sure it's right.

Be aware im NOT an expert but this is not some witchcraft.
I see this car has wheel spacers.. after checking everything in the front suspension try test drive the car without them, and a other set of tires if possible.
Running much negative offset on the tires make the steering very sensitive to unbalance in wheels and worn out parts.
Lift the car up and lower it to rest on it's axles on a WERY sturdy pile of wooden blocks.
Start the car and run it up to speed at least to the speed where the wobble exist.
At the same time watch the tires for vibration, not being circular, not warped etc..
Then you wil really find out if you have a set of balanced tires on exactly YOUR car with that set, maybe your spacers are badly machined etc.
Wide rims and spacers that give mutch negative wheel offset witch mess up your scrub radius that is known for causing wobble issues.
What i been told is lower your caster close to the minimum spec and the toe in close to the lower specs from the car manufacturer if you run tires with very negative offset.
Of course upgrading the steering system will also help like it's done in this video.
If you really want the wide look and tires outside the fenders the best option is to upgrade to a wider axle but that is obviously not a cheap route..
@jada1173 👍
What about the TPMS? If i reduce the tire pressure to low on my Jeep i get a Low Tire Pressure warning on the dash.
There is a threshhold (I think it's 32psi?? - please correct me TPMS experts 🙂) if you stay above the dash light will remain off. If you go below that, you will have to reset them by going back up to a certain pressure (37psi?? again please correct me if I'm wrong). Alternatively, there are products on the market that can turn that light off permanently if you are wanting to run a lower pressure or if you decided you don't want to use TPMS sensors. I use the zautomotive.com Tazer. It has a lot of great features for the price.
great vid thanks
