Shaking disappeared for me when I replaced the rear bearings..the bearing on the passenger side was scored pretty good, inside of the axle was shaft was also scored. A little sand paper and new bearings...problem disappeared. Secondly, my brothers friend had the shake, passed on the info..same fix,...all is well. Figured i'd pass on the info.
I replaced pretty much everything on my truck. But in the end it was the road force. I had my wheels and tires road force balanced four times from three different locations and still shakes 65 plus. The last place I went to the guy said he had 14 years doing balancing and 2 of my OEM wheels and 18” tires he could not get below 40 on one and 22 on the other. IF They are NOT BELOW 15!!!!!! Your truck will shak guaranteed. They all balanced out two 0 but road force two high. Bought New Wheels and tires had road force balanced 3 times . Last time stood outside and watched each tire road force below 15 now rides perfectly smooth!!!! The problem is most tire techs do not know how to road force properly. If you don’t stay and watch each tire get done you will get screwed. Do some research on road force before you take it in. The road force is different than balance!!
Ok so I have a 2014 Silverado ltz crew cab and I've done everything I can to fix my situation and I don't know if it's a Chevy shake or not but what mine does is more of a bounce then a shake. Between 40 and 75 I get a very bad bounce and it's not all the time but after hitting a small bump in the road the truck continues to bounce. It's very annoying and embarrassing, u can actually see it at the tailgate if u look in the mirror. When I bought my truck it had a 3 inch lift and I didn't have it then. About 5 months after my transmission failed and got a new one. That's when it all started. Ive changed the shocks and struts, break pads and rotors, 2 sets of tires and balanced them at three different shops, even put it back to factory height nothing has worked. I didnt think it would have been the transmission but I went ahead and had that checked out and everything is in good condition including the trans mount. I'm absolutely lost on what to do now. The dealership just wants more money and they can't guarantee a fix. After everyone changing there body mounts and drive shafts and it's still not fixing the issue has me pulling my hair out lol. I want to do the body mounts but I'm hesitant.
I've heard that people replace the axles. That the hub is not centered on the original ones and they fix it by going with aftermarket axles like yukon ones.
One of the first things I did.
Simple rule of thumb. Anything you feel in the wheel, is in the steering. Anything you feel in your butt is the drive line Anything you feel in the brakes is in the brakes.
I've been looking for a video like this for a while. I have the same issue with my 2007 Ford Expedition Limited. Great Truck, that's in great condition, but it shakes severely when rolling over any size bump and it shakes the seats. Driving at high speeds the vehicle is stable but if I hit bump, severe shaking that jeopardizes steering control and that scares me. I've had the suspension checked by dealer and other mechanics and no one can find a suspension problem. I've replaced the struts, springs, and tie rods and have had all the bushings and joints inspected, no issues found. But there is definitely something wrong. Feels like the body separates from the frame when hitting a bump. So, your video is making me think there may be issue with the body frame mounts, which no one has suggested yet.
Did you ever get the issue resolved? By replacing the body bushings?
I have a 2015 Chevy 1500, I took off my running boards and brackets that were held by 2 body mounts on each side of the truck and I put the bolts back in & now I hear a clunking noise as the bolts or body mounts are hitting the frame when I am driving around uneven roads and braking.
Gadgets and gears took his truck to performance drivline in. California the put a 2 piece drive shat kit in his truck didn't fix it then put an aftermarket aluminum one in which was thicker and not knecked down and it helped alot but still a little vibration
🤔im thinking it's the trans mount, I balanced the tires, replaced the drive shaft, and checked the pinion bearing🤔, could also be the tail shaft housing bolts or the tail shaft bearing 🤔,
My shake is through the seat as well I’ve also owned two 2015 one brand new 2wd crew cab short bed it has the shake also currently a 2015 RCSB 4wd. It also has the shake and it’s the worse I’ve felt. To the point it feels like it’s going to break something at some point. It’s not constant but noticeable at highway speeds more so than any where else. I went from lift 3”’s to lower 4” front 6” rear new rims tires rear shocks front upper lower arms w/ ball joints bushings as well as inner outer tie rod ends. Checked for oblong axle issues. Then one day on dry Arizona highways I tossed it in 4wd for the drive home from work (25 miles) I noticed the general shake was lessened but still there, as well as well I shifted down or raised my RPM’s the vibration seem to follow the motors RPM and mor aggressive shake. I feel this is a internal problem in the transmission that resinates through the rest of the chassis and other areas reverb the vibration cause it to feel more like driveshaft, axle, frame beaming. Now I’m not for certain but I feel if someone was to swap out the transmission to a TH-400 or maybe even a 4L80E it might eliminate the shake. This is one of my plans fir the truck however I’m not able to do that yet. It could be a poor design and use of inferior metals or even a program flaw or both. It seems to follow the newer 6 speeds as well as the 8 speeds that were just recently recalled.
Have you noticed the steering wheel is cocked to the left. Maybe it is in your steering box
where you able to fix the issue? if so what was it?
Ive had to do driveshafts that vibrate about 80 90 klm..sometimes just a ujoin but ive done deiveshaft...thank you wrecking yards for cheap parts
Have you ever replaced a chevy control are frame mount?
Is there such thing as an inexpensive mounting bolt? If so, where can I buy them? Thanks for the video!
Thank You for Sharing this experience. I have been contemplating one of the "shakes" coming from steering box... space in gears, excess radial (up and down) play in steering box output shaft, amplified by the re-resonance overtones coming from ported cavernous spaces, chassis rails, cab interior, etc... since it is bolted to frame, any sound it makes up there would be heard out back, and the cab acts like a ported/unported speaker box, or guitar body... Im working on an older one, experiencing a long wave frequency from 35-65mph, fades (or modulates with surrounding frequencies, idk) at 70mph and gets smooth. To me, it seems going faster is like tuning up on a guitar string, it has a wabble overtone until it "locks in" tune with the other strings... curious. I will make a vid if the new steering box, ball joints, and tie rods fixes it. Happy Day Sir🚂🎼🌹🎵🎶🛠🔥 ~C< 3)>>-Z->}
Following up.....did any of this correct your problem
@@kyleabell7864 it was a combination of driveshaft bearing, and front a-arms/ball joints. I replaced the whole front end and balanced to 2pc driveshaft, with new ujoints. Fixed it.
Good luck with it. I 'was' thinking about buying 2015 Silverado, but not so sure now. I HATE vibrations!
Take it to to the 65-70 range and you'll know instantly. I've had a 2014 and two 2015's and only this one has the vibration issues. But it's been a good excuse for me to install a lot of cool parts on this truck. I'll figure out a way to convince my wife a tub job with some 15" wide tires is a solution eventually!
@@GoatRopeGarage: I recently test-drove a 2015 and noticed mild shake at 65-70. I was thinking about making offer on it, then learned of (and started reading about) the infamous "Chevy shake". Now I can't buy the truck. Too bad, 'cause it's nice.................
@@ChevySS1968 Dodged a bullet. And the big issue is there isn't a singular fix, it ranges broadly as to what had worked for different people.
Anybody know what causes a loud banging when going over bumps like a recessed manhole cover... its like I'm hitting metal to metal across the whole front dash, very loud noise, its not a clunk its a bang!!!... its a chevy astro
Think bad body mounts could be doing this?
maybe transmission mounts?
@@Hallboyjr ok I changed the body mounts, that helped about 60-70% of the noise...
Then I changed the rear springs, that was another 10% (they were bad)
Then I changed motor mounts and trans mount.... now it's quite as a mouse except over very large holes, might need to change control arm bushings, naively all the rubber was shot across the whole vehicle... swapped ujoints as well, thing runs great now... plus the s10 spring s have a nice rear lift of 3"
@@ThisIsSolution i just bought an 01 sierra about 6 months ago and it’s always had a shake to it underneath the passenger door when going 65+ i’m gonna change the body mounts first and see if it does anything if not i’m thinking maybe springs or shocks?
@@Hallboyjr check that side tie rod as well
Does anyone know if these mounts are covered by the warranty ?
I heard some people say there’s was a bent rear pinion yoke.
Do you remember what your road force balance numbers were when you had the tires balanced?
Been a long time, Dave, sorry.
@@GoatRopeGarage no prob.. just wondering if that was a contributing factor in it..
Drive shaft and axels help mind all together
Did you just get new axles or aftermarket axles
I went with Yukon axles
@@GoatRopeGarage I went with Yukon’s as well and same shake
Mounts may cover the issue. They will not fix the issue
TORQUE CONVERTER IS SAID TO BE ISSUE...
Didn’t fix ours on the tahoe
Just put new tranny and circle d after market torque converter in mine and didn’t fix it. Also put in a new driveshaft
Are those body mounts a service bulletin and are they only for 14 to 16? I have 17 High Country 6.2L
There was a TSB but I don't know what years.
@@GoatRopeGarage Maybe 17s and up have the new ones
Trans fluid swap cures the shakes
Body mounts will not create this. whoever said that is wrong.
That being said i would investigate something in the drive live/trans. If you have the 8 spd trans, GM is having issues with them. The speed/vibration your complaining about is usually associated, with u-joints ,and or drive shaft. but if you have the 8 spd i would question it.
Oh yeah check the torque converter and bushing.
Where did you buy the body mounts?
Just a GM parts place, they are part of a service builtin
Ima buy the parts
Me personally..i always go with the 1 piece driveshaft..
Critical speed is an issue on the one piece
If it’s an 8 speed trans, it’s no telling what it is. I’ve seen so many different things people had to do to fix it. I have one with the 6 speed. No issues. Will never buy the 8 speed trans that GM/Ford co designed. Some ford trucks are having the issue but not nearly as much as the GM’s
I have the 6 speed and I have the shake
Ctb 281 torque converter getting ready to blow. Known issue apparently.
@@ctb2814 how do you know which one you've got?
That body mount is worn out from all that slapping
Actually the one he took out don't look to bad. Ive seen way worse
Mine was in a 2017 Silverado due to bad transmission fluid.
My truck shakes when I go 75 I don’t think that’s normal lol
I really wanted to buy a new Trail Boss, but I’m not risking all this craziness.
agentd36 I HAVE A 2020 RST DIESEL WITH 3K MILES AND SO FAR IT IS VERY SMOOTH AT ALL SPEEDS. TAKE A GOOD TEST DRIVE IF YOU DECIDE TO SHOP FOR ONE , THAT IS WHAT I DID.
NOAH DUNAWAY thanks
I'm sure the issue has been fixed by now. Just as im sure GM is aware of what the issue is.
When are people going to learn it’s their tires that are out of round go get them skimmed and balanced and stop running 80 psi worth of air in the rear tires iv pulled 20000 plus pounds forever on 65 psi frame beaming gone these trucks are stiff a round tire goes a long long ways
So did this help with the vibration or not much?
Not enough to say it was a for sure fix.
mine shakes bad, can we sue gmc?
A one piece, necked down, heavy gauge aluminum drive shaft will help as well, but wont completely solve the vibration. The true source of the vibration is in the torque converter
WrenchBoostBoi 89 are you serous ?!
Please explain
@@joemedina2249 yes please explain... brought mine to 3 transmission shops and all three said it wast my transmission... and bought a 4” driveline that didn’t fix it either
Stop smacking it 😢
Buying a Ford has fixed all of my Chevy issues.
I'm on my third Ford work truck in two years. And this one has an oil consumption issue, so I'm guessing I'll be in my fourth in two years soon.
I don't think the DEATH WOBBLE is a better solution than having the shakes.
FYI, the issue has been resolved finally with the Mobil 1 transmission fluid swap. My 18' wasn't very bad, but it is a none issue now thanks to the tsb.
Good luck with that death wobble.
Hope you and your Ford aren't found on road dead.
@@GoatRopeGarage for some reason Ford states it's normal to have oil consumption. They also like to blame the gt350 voodoo engine grenades on owners as well.
B
I buy a vehicle to drive not to be always working on it. That’s why I buy Ford.
Fix or repair daily
Vibration is from something not proper..driveshaft..tires....different tire tread...im seeing the new automatic 6 and 8 speed transmissions are junk...
I've used a vibration analyzer and replaced every rotational part at that frequency
@@GoatRopeGarage im old school.i use parts from the junk yard until something works.....any idea what kind of antifrerze goes in a 1990 6.2 gmc...bought my first diesel in 40 years...i have no clue on the old diesel..the old 6.2 was based of the 5.7 car engine so no idea..i dont know if i use good old green stuff like my cars or something else.
Trans fluid swap cures the shakes
MrVegaslive what type of o transmission oil
@@MrVegaslive might fix the 8 speed but not the six speed... had my 14 done twice and filter replaced still shakes...
Ive used hocky pucks befor. And they worked great..im thinkimg gm has gone to shit.
I used hockey pucks on my 67 and 68 camaro sub frames and they worked great there!
Mobil 1 trans flush/swap. Problem solved...
Your vibration was fixed with a transmission fluid change ? Can you elaborate a bit on this? I am at my end with my 2016 GMC duramax. Vibrating is insane. Tried three different sets of tires already. Thinking about body mounts next.
