- Over 70 mph vibration during acceleration only, caused by tapered rear lift blocks. The fix was to use straight cut blocks. Below is information on the kit I used as well as other tools and related videos. Tuff Country 79062 Block amzn.to/2i2opGB

Nice job. I've worked with a few lift kits in the past and first lesson I learned was keep your drive line angles under 5 degrees or you'll wear out u- joints.
We have been fighting this for years on the long wheel base F-150's there has been multiple fixes from Ford and this is on stick vehicles so you are not alone!
Thanks brother. Merry Christmas!
Good example of the importance of correct and equalized u-joint working angles! If your vibration did not occur until high driveshaft speeds under a load, the difference between your u-joint working angles must have been at the maximum allowed; the acceleration caused the pinion nose to raise just enough to take it out of equalization and give you a second order driveshaft speed related vibration. Merry Christmas from Utah!
So many people mentioned your channel. I need to check it out for sure! I'll put you on my channel home page if you return the favor.
Oh and most importantly, Merry Cnristmas to you too!
I just deleted my comment by accident. That sucks. You'll still have part of it in your email. I was just talking about the truck
Done. It is good to see other automotive instructors taking advantage of RUclips to help their students as well as anyone else interested. Keep up the good work!
Mine shakes at 6 to 7 km but ride is smooth it this normal?
I have a 2008 F150 Limited…Thank you for helping me fix my vibration problems … you wouldn’t believe how much money I’ve spent trying to figure this problem out.
I'm so glad this helped you my friend
Great to see Frisco Noticed on your page!!! I watched a lot of his jetski (polaris) and boat repairs videos.
Great work so far man! I can see you are approaching 100 k subscribers, they'll be definitely a lot more, you sure are deserve it! I've learned a lot from your videos, please keep them coming. Merry Christmas, this time from Romania...you got some serious European support here : )
Thank you Lucian! Merry Christmas to you too
Amazing how geometry and physics work in the universe. Glad you got the annoying problem solved. Now you can enjoy the truck more
For sure
scannerdanner you are a true american classic man. Im a 23 year old GM tech Alberta boy born and raised. Anyway man your a big role model in my life. Its pretty cool you are willing to help people you don't even know, il do the same when I get to your level. Thanks brother. Im going to be buying your paper book.
Q
I'm subscribed to Friscoboater's channel in addition to your channel. The guy name is Jay. He lives in Frisco Texas, and his main interest is boating. Got into the boating scene because of Jay' channel. Bought a Seadoo jetboat and a Polaris jet ski after watching all the fun Jay was having on the water. Unfortunately, Jay went through a divorce this year and had to get rid of his big boat. He a jack of all trade, master of none. He's a DIYer of anything and everything.
Tell him I said thank you!
@ScannerDanner merry christmas and thank u for all the good videos here and in the premium channel.
Merry Christmas! It great to know that there is people out there that can help us. Thanks for letting us come along.
Merry Christmas to you too my friend
I believe the term you are looking for is "phase"
Sounds unusual like you were thinking. The term has different meanings though.
In this case what you are looking for is
"The 2 u-joints need to be 'in phase' with each other"
If they are at different angles they are 'out of phase"
Good info
Old school hot rodders know about this type thing. When building cars or trucks you spend a lot of time with the angle finder when doing spring mount perches. Which is what I'll be doing of my xmas weekend. Can I make a SRW Dana 60 into a DRW and fit my 1951 Ford 3/4 ton truck..... we shall see
Thank God for our RUclips brothers
For sure!
Good video That is true on the angles , and also when lifting one a lot , some u joints will work on steeper angles than others will . But would run into that more on short wheel base or big lifts
Friscos real name is jay he does amazing tv and stereo work and does excellant boat restorations!
everyone should know and understand driveline angulation and its effects . even though we mostly use cv joints these days. anyone working with trucks with air suspension has probably run into it. more than once set ride height by measuring driveline angles (on the fill stroke)
Nice. Thanks for the comment
I know the video is a couple years old, so was the taller end of the lift block installed toward the rear of the axle?
Taller end toward the front
@@tommytilley843that maintains pinion angle alignment.
I remember reading about driveshaft alignment and vibration in an automotive tech class. One would think that the U joint would compensate for the difference in the flange angle. However, if they are not parallel you get a vibration. Used to run into those problems back in the day when we put air shocks in the hot rods to get the big wheels in the back (high school days) we're better educated today :) back then no one cared about vibration....., just the horsepower and far you could lay a strip of rubbe!
Merry Christmas to you and your family Paul.
You know who made the Pico software algorithm , I asked Pico at the training in Wolverhampton UK the guy in a wheelchair. I said that's John Kelly yup that's him. I am on the waiting list for Android app for vibration from Weber Auto
Merry Christmas scanner and fellow techs
My truck vibrates all the time 60 mph + on rough country 6 inch block which is very tapered. I switched to balacing beads because i thought the mudtires were the issue. Driving me nuts, i can't figure out what the problem is. I'm going to give this a shot. Wish me luck
I bet you fix it.
Any new result ?. I switched to straight block and it didn't fix my very very similar problem
did you ever get this resolved? thanks
@@ebaysnipa yes it was the tires not balanced correctly
@@MoosePhorus Thanks for replying I have a rough country lift too and I think I’m battling two different vibrations and was thinking about going with the balancing beads. did those not work for you I guess?
In heavy duty, the standard use of the term phasing refers to the alignment of the u-joint caps. I would assume it is the same in automotive.
Sure hope this doesnt turn you away from aftermarket suspension parts.. i have angle cut blocks from rough country on my 03 that are a half inch more then the stock z71 angle cuts gm comes from factory with.. no driveline issues.. the angle might be cut to steep? And yes I am resigning up for premium when cash flow starts again.. xmas and all.! merry christmas aha
hi "Danner" First wish you a merry christmas, Second thank you for the time you spend for these educational videos and third, ask you, if you will make a video of how GM monitors the successful ignition in his 4-wire coils like ls2 version?... I know that in the toyota system each coil has integral diagnostic detection electronics, and when a coil successfully fires, it briefly pulses to ground as a confirmation pulse to the PCM...
Was any of this mentioned in the instructions , seems odd the lift kit manufacturer would not have had some feedback on this vibration. Merry Christmas
No mention in the instructions. The guy I spoke to about it originally wanted me to talk to tech support but I never called. I knew what my issue was at that point.
Merry Christmas Steve!
This is literally the exact same symptom I have on my truck! I have a 2012 silverado 1500 4x4. I installed the 3.5 inch rough country level kit and since I have a bad vibration at 65-70mph but only under a load. If I reach 75 mph and cruise the vibration is gone but if I give it gas it comes back. I do have the taper rear blocks. I will install straight cut tomorrow and see what happens! Hope this works!
You'll be loving me tomorrow :-)
What's the word man?
Results good after changing???
Thank you for this info i have ordered the correct blocks. What was your final ride height for the front of your truck? Im at 42 inches and i still can crank more on the torsions.
I don't remember? Sorry. Just remember the more your tweak those torsion bars, the stiffer your ride will be
Paul, Merry Christmas to you and your family, take care.
A strong greeting from Spain =).
Merry Christmas Pablo! Was that you last year that sent me a video of your daughter saying hello to me? If it was, thank you again!
No sorry, I haven't sons. =)
okay no problem. But I do recognize your avatar and user name both here and on facebook and you are always so supportive. I am grateful for you my friend from Spain
ScannerDanner Thanks for your kind words,I try to have social conscience. I just bought your book (a few hours ago) is really good you are an example as a person and professional =)
Your book is awesome for the best.
Thanks again Pablo A!
email me paul@scannerdanner.com and I'll get you a 30 day coupon for SD Premium. I offer this to all my book owners.
Wow Paul, not knocking you but I am surprised you did not know that. Drive-line angle should always be a close match from front to rear. I would send that lift kit back lol no telling what else they screwed up.
Merry Christmas.
Merry Christmas to you too my friend
Ralf V From what I've seen, Paul is more numbers, electrical, scopes, etc. kind of guy. Yes, he does hands on repairs too, but something like this is more on the mechanical aspect of things, as to where he's on the diagnostic & driver's side of it.
How often do you come across something like this in the electrical diagnostic end? Never. It's only when he had a personal experience did he have the opportunity to delve further into the mechanical drive side. As I'm sure you're aware, transmission & differentials are a whole different animal, which to me, it's more likely a trans guy would know this as common knowledge over engine or diagnostic guy. Just saying & giving my personal opinions (not trying to be "ranty" lol).
Merry Christmas Ralf!
It was a bit of dry humor. don't read to far into my comment LOL. We all love Paul! Just got to keep him on his toes LOL
exactly my friend. I am absolutely a rookie with this type of stuff. I just don't deal with it...ever!
And I knew Ralf V was messing with me too.
You guys are both great! Thanks so much
Wouldnt the direction the block is facing mater? If the shorter side was on the back side of the axle it would raise the front aligning it properly?
Steven Warren shorter side should face forward. The higher side should face toward the back.
Erg! Yeah, driveline angles are critical, and even small variances can cause big changes. There's a great short video illustrating it here: ruclips.net/video/gmV4qwLfOMY/видео.html
I've seen things like worn suspension cause driveline vibrations, and it's one of those things that kicked my butt 'cause I just wasn't as aware of it as I am now. A driveline angle gauge is priceless when you're changing suspension geometry. :)
Glad you got the issue sorted out!
I know I'm 6yrs late on this but I'm hoping it helps those with a 2019 or older Silverado.
I would get a highway speed vibration after my level kit was installed. I replaced most of the suspension, including CV axles and hubs. Even switched from the 3" tapered blocks after watching this video. Nothing worked, the vibration was still there. Right when I was losing hope, I saw an old forum post saying he had the same issue, nearly all same parts replaced, and finally he switched from 4wd auto to 2wd high and VOILA... vibration gone.
I've driven this truck (2018 lt) in auto since I got it. Never thought it could be the issue.
Great tip! To be clear, you always have driven it in 4WD auto and it didn't start the vibrations until after the lift?
Thanks!
@ScannerDanner that is correct. So I never gave it any thought, but sure enough that was the issue
@@Th3ev1lkn13val so ultimately your vibration then was from a front driveline angle issue. At least that's what it sounds like
@ScannerDanner I'm no expert so I can't say. But the vibration was coming from the rear. Not sure if that factors in
amigo. merry Christmas
It's a hard concept to accept when everything you've always been thought says you need to tip that pinion up. However the graphic showing how they needed to be parallel help to make sense of it.
Did you see this short video? ruclips.net/video/Idk3BVDVHq4/видео.html
I linked it into the description of this video. This is the one that really shows you why we need to care about working angle of the driveshaft
I had not seen that. Thank you for the extra push to it. That is unreal and a great educational video! I'll be ordering straight blocks! Wonder if zone will reimburse me. Lol
They absolutely should! I linked the straight cut blocks in this video too. It's an Amazon link I believe.
If you need additional info on this. I actually have proof using a vibration analyser and have before and after waveforms. I made a video on it with my class at Rosedale Tech. too. It's on a paid channel but I can unlock it for you so you can watch it if your interested. It's about an hour long and not really necessary for you but let me know
ScannerDanner that's really kind of you but frankly I'm good with the info thus far you've been very helpful and your follow through has been astonishing. I'm very grateful.
Cool man. I'm just glad someone actually is making use of this video series! This isn't what I normally do.
Thank you for this information !
Merry Christmas to you and family and friends regards Noel .
Merry Christmas!
Merry Christmas to you and family and friends 🎅
Interesting way to diagnose. Why not use an angle finder or a digital protractor to measure/compare pinion angle to transmission output shaft angle. Additionally, shims are available in different degrees to make adjustments if the angle cut or straight cut lift blocks by themselves won't cure the issue.
And angle finder is fine once you know what your looking for.
Good tips, thank you.
do you have a 2 piece rear driveshaft? any lifts that I have done where I work, if there was a vibration the was because of drive line angle, we always put spacers on the steady bearing, so it straightened out the driveline. I've never heard of changing the blocks to straight cut ones. usually any BDS lift I have done always came with spacers for the steady bearing to straighten the driveline. but not every truck needs them.
Are you sire the blocks werent installed backwards? The slant seems to be to correct the pinion angle.
I don't think so. Since I never moved the transfer case mounting, putting the block the opposite way would have had the same effect but in the opposite direction
Makes sense.
I installed a 4" rough country lift. I'm experiencing the same vibration. do they sell 4" flat blocks to fix my issue?
Had to by the flat blocks from another company. I think the link to the company is in the description or I mentioned where I got them in the video?
Hey there ScannerDanner....!!! I got a Question I got a 1997 Gmc Sierra 1500 2WD I'm looking for feed back, any suggestions about lift kits for it? What kind of lift kits would be a good fit for it? I'm just Looking to gain enough hight to fit some 32" or 33" tires about 1' to 3'' inches in the front and maybe 2" in the rear Ihope to get some feed back from you'll..!! please guys need to get this lifting done on my truck soon I got wheels sitting around waiting for it.? thanks Scanner Danner and everyone else in advance for you'll suggestions Merry Xmas to you'll.
Hey Danno, since its been a while since the lift, how are the zone shocks holding up? Interested in shock durability.
Still good my friend
Thank you much really helped me out!!!!
I wonder if this is the same for the half ton trucks, installing 2.5" blocks tomorrow everyone says use tapered, I guess I'll find out
I had tapered 2" blocks on my old 77 Dodge Power Wagon (1/2 ton) back in the day with no issues. The straight cut blocks fixed my pinion angle issues and the vibration here.
damn paul, only you would use a Picoscope to solve a driveline vibration.
After lifting my truck, I have noticed a distinct shake at 45 MPH only in the rear. Would this be the fox for my issue?
yep, I am confident of that
What year truck do you have or does it not matter because i have a 2020 GMC sierra 1500 and did the cognito 3" lift level kit with 2" lift blocks and right between 70-80 if feel the slightest vibration and its very annoying.
It doesn't matter. Are your blocks tapered in the rear?
@@ScannerDanner i installed them with the taper taller in the rear and shorter to the front.
@anthonysalamun1965 yeah same as me. I'd get rid of them and go with a straight cut block like I did
If anyone can help me, please reply.
I am getting very conflicting information about my lift blocks. I have a base 2wd 2008 Ford Ranger. I am only installing a very mild 2inch set of lift blocks, no different springs or shackles.
I bought a set of blocks from a well known company. When I got them , they are tapered. It seems unnecessary for my situation where we are only talking about 2 inches of lift.
But, according to everything I have seen, the large end of the block is installed toward the front of the vehicle.
Or, should I return these and find some flat cut lift blocks?
is there a front diff drop installed??? when you have a taper block installed??? just a curiosity?
Yes there is but nothing is done with the transfer case. It stayed in it's normal place.
Have a 2019 GMC Sierra with a 6” Rough country lift kit and this vibration crap is causing me to lose sleep after all the money I put in my truck. Any suggestions for my truck?
Did you figure it out for your truck? My 2017 Silverado with a 7 inch RC has crazy vibrations when you get above like 65mph
@@d.parker106 Sure did. Tires were not balanced and badly out of round. I did a video on it. visit my channel and check it out.
@@bigshane4ever930 Thanks! I will definitely check the videos out. I’m hoping that is the issue with mine and it will be a relatively simple fix.
Emailed the forum never heard back from you. Is that site still im use?
My Web designer handles the forum login issues. Email support@scannerdanner.com and describe your issue. He will respond within 24 hours. Thank ms for your patience
ScannerDanner hello there sir. I have a 2015 ram longhorn. Eco diésel, I recently put a 6” lift pro com. so I go on the highway 60-70 mph shakes a lot. Like my seats is shaking everything. I did alignment, tires, checked everything even put new brakes. Help please. Have not change the blocks I really don’t know what blocks it has but I will check. Thank you in advance.!
Just stubble across this video cause I just did a 3/1 motofab leveling kit on my 2015 silverado. I'm get a weird vibration and droning noise I can feel it in the steering wheel and gas pedal. It has a little squat of about an inch. Does this seem like that same problem you had.
I feel it a multiple speeds as well
What kind of block was placed in the rear? Was it tapered?
@@ScannerDanner it is tapered. So I was figuring I'm having the same problem. I just was sure if the symptoms I am having are the same? It almost feels like it is in the front end but at times seems like the rear it's weird. I ordered 3 inch flat cut rear blocks just to see if it will change things.
@@richardcerato8099 turn the blocks around and try it. The straight cut blocks fixed mine, but I'm wondering if I put the taper to the rear (opposite of what I always thought) would have also fixed it?
@@ScannerDanner I thought about doing that but since I ordered flat blocks I might just wait until they come. The original 1 inch blocks that came off the truck were straight cut aluminum blocks. I appreciate the advice and your video is great I would never have new about this potential problem. I even took it to my local shop that deals with 4x4 lifted trucks and they went for a ride with me and they said it didn't sound like tire but it was definitely strange. Now they didn't have time that day to dig into my truck so I figured I would try this first and if I have no success I will bring it back to them.
1/8" difference in taper height is not going to matter. I am running tapered blocks with no issues, but they are fabricated (2014 Chevy Silverado 1500). That makes all the difference. Tapered cast blocks will cause vibration
Flat blocks was the fix
@@ScannerDanner well asking around and talking to several professional four-wheel drive companies I have found out the more defined answer. Anytime you go over 3 in you want to run the tapered blocks due to the fact your pinion needs to roll back in place anything 3 in and under the flat blocks are fine. This is probably why the flat blocks work on yours versus the tapered blocks work on mine. I have a 5-in lift. Best thing to do before buying a lift kit is to take your drive shaft out and check your angles to determine which blocks will work best to keep your angles correct.
@@michaelflowers6048 which way did you install the taper? Just curious. I'm wondering if I would have installed the tapered blocks with the fat end toward the front, which would have made for a steeper pinion angle if that also would have corrected it? Either way the flat block was the answer for me.
@@ScannerDanner on tapered blocks the taper always goes towards the front. Another thing depends on whether you have three U-joints or two U-joints
@@michaelflowers6048 and that's what I've always thought top. Some were saying in the comments that I put them in wrong. But I did put the taper toward the front. Thanks!
Where can I buy these straight cut blocks? Every one I see I tapered
I think I included a link in the description
I have a 6” rough country lift on 07 Silverado and it has a bad vibration at 65 or higher and it gets worse until 90 then it doesnt get worse or better until you get below 65 do you think it could be because of the anti axle wrap blocks (it’s cut at roughly a 15/20 degree angle) they use I haven’t tried different blocks yet because I’m just tired of spending money trying to fix this problem because I’ve taken it to shops trying to get it fixed and no luck after $500 in mechanic bills and it’s hurting my bank account with me being in college for 10 hours a day and only being able to work part time
Absolutely, straight cut blocks should fix your issue
Brayden, I have have the same issue with a 2014 Silveraydo with a 6" Rough country lift.
@@verndeselms858 if you get straight cut blocks it makes a world of difference and I still have the truck with the lift and the best thing you can do with those blocks from rough country is throw them in the trash they are absolute garbage
@Brayden I believe that they are 4.75 lift for the rear It is a 6" lift kit that also levels. I don't know if anyone makes a 4" to 5" straight lift block. I might consider lift springs. Thanks for replying.
@@verndeselms858 I found some off of eBay at 4” that one of my friends used on his truck and I had a machine shop fabricate mine at 5 1/4” so I’ll still have the rake and it’ll level out while towing
You are correct but when the attack angles are not the same for both ends of the drive shaft and contrary to logic, the input and output shafts of the drive shaft are turning at different speeds. This causes "at some speed" harmonic distortion between the output shaft of the transmission and input shaft of the differential. Here is a video that explains: ruclips.net/video/Idk3BVDVHq4/видео.html
This is the exact video I linked to in my description. Thank you!
Is there any diderence between a block or extra springleef?
Yes
So I recently lifted my f 150 2wd 6.5 inch front and 5 inch rear tapered block I already got an alligment but still vibrates/shake when I drive off and when I brake. any ideas what’s going on ?
Shaking during braking is typically from a warped rotor.
Shaking when pulling out at low speeds is not going to be from a driveline angle issue
Thanks for the response ! So having a tapered rear block causes vibration ? I’m trying to find a flat 5 inch rear block but can’t find any
@@jessealaniz918 it completely depends on your pinion angle. Your description doesn't sound like this issue
On my 08 Silverado I have 5" rough country lift blocks and the angle cut on them are pretty extreme. I had to use 6° angle shims to counteract the angle. Bad part about that is when the blocks have that much of an angle cut added with the angle shims, it put my axle back about 1-2" from where it is intended to sit. I didn't realize that until I was on my way home one day and some *sshole slams on his brakes causing me to slam on mine and my driveshaft yoke slipped out of the rear of the transmission. Luckily it didn't do any real damage but all I really have to say is screw lift blocks. Unless anyone has any advice that I'm failing to realize, I'm switching to lifted leaf springs and hope that fixes the issue.
did it work?
@@00thehunter97 i switched to a 8" Superlift kit. It took care of the issue. I don't have any pinion angle problems, no vibration. I should have done it sooner, instead of cheaping out, trying to save money.
@@somanynamesilltrythis0180 yeah i tried to cheap out. I have LEARNED MY LESSON. I lifting my truck and got these aftermarket lift blocks along with the lift blocks that come with a lift kit originally I had the lift kit blocks on and there's no vibration but the aftermarket ones are angled and I put them on recently and I've had a terrible vibration so I'm just going to switch back and pray it fixes it. Thanks for replying even though you posted 3 years ago
apparently frisco boater doesnt check his emails
FriscoBoaters name is Jay
It’s not phase it’s Pinion Angle and pinion angle needs to be pointed down at least 2 degrees !
I got 2inch rear blocks on a 2wd f-150 and it shakes when I brake ? What can it be
Shakes when you brake is typically a warped rotor. When did this problem start?
@FriscoBoater's Garage
I have 285 75 r 16 Goodyear Wranglers. I believe they are 32's
My 275 65 18s are 32.1"
I just put on 285 65 18s and I think they are 32.6
Can't you just use a 2 degree shim? That should bring your blocks to level. Pro Comp Suspension Degree Shim 99-200B.
I believe you could, but I didn't want yet another block in there, so for me the straight cut blocks was the answer
Hi Paul,
Would you see any diference between a block lift or a extra springleef?
Mr Danner, how do you know you have a vibration above 80mph? Your speed limit is 55 over there lol
55?! thats so slow. motorway is 70 here in the UK!
We have 70 mph zones now brother
I know, I was surprised a few years back when we went to Florida. You guys still drive on the wrong side though !!! I did make the car hire company take back the Hyundia and give me a Dodge Charger. No way could I not have an American car over there.
Have a great Christmas Paul.
80 MPH here in Utah!
He did 80.
What up Paul
Nothing man
Hey man, when I grow up, I wanna be just like u
haha okay
Guy, you had a pinion angle problem is all.
Yes sir. What threw me off was having this same vibration on a 10 hour trip to the mountains BEFORE the lift kit was installed. But I had a loaded bed (7 snowboards and gear and food and coolers etc) and it would only vibrate (same exact vibration) above 80 mph.
Thinking back, this too would have been a pinion angle change with the loaded bed.
Tuff country is a big disappointment they talk a big game and sold me on a level lift for my tundra and it rode terrible
80 plus mph. you got a heavy foot....
phil holbrook our speed limit is 80 mph in texas...
That's why you leave the damn thing alone
That's no fun :-)
Look how much I learned!
Haha, I love thst response!
