Good news. Changing the ring & pinion gear eliminated my above 68 mph vibration. I will say correcting this issue is 100% due to the diligence of the assistant service manager at the dealership. GM Custom Care was of no assistance.

Well folks, I did it. After all the failed attempts at the Chevy dealer I traded it in for a 2015 Ram 1500 Larame. I have to agree with the other folks on here that have done the same thing, it was th

Apparently you and the other customer reps don't care. If you or GM would care y'all would put more effort in the matter. Just coming on the forum and stating the same repetitive posts and being a 3

How bad was your vibration? I have a slight vibration at 70mph in the steering wheel and just wanted to see if that's what you had going on

First post, ended up here hunting down a solution to the 70-80 mph shimmy my truck has intermittently. Truck is a SCSB Z71 4x4, 5.3 with the 3.42 gears, love the truck... hate the shake since i drive everyday on the interstate and i have to be doing 69 or less or 80 and above to keep my coffee from shaking out of the center console.

After 5 weeks straight in the shop for the 45-55 mph steering wheel shake GM engineers tell them to rotate tires which still shows vibration coming from rear end. Head mechanic wanted to order a new rear end 3 weeks ago but GM seems content to push me to the boiling point. Somebody is going to pay for this BS and it's not going to be me.

this is about average for most people but for some its not this bad

 

 

 

GM's official position on it is that the truck is working as designed and trucks are supposed to ride like that and its perfectly normal

The vibration on my vehicle was severe enough that the rear wheels felt like they were hopping at 75 MPH.

Your video is exactly like the condition my truck had. I used a phone app that records vibration to show the dealer. I would insist on checking the ring & pinion gears (backlash out of spec). That was the solution after tires (replaced Goodyear with Continental), wheels, shocks, and balanced drive shaft.

 

On another note, GM Customer Care was unresponsive/unhelpful until I filed a BBB Lemon Law claim.

Great video series keakar. Glad to see more vibration complaints finally making their way over to the NHSTA office of defects complaints. Keep up the good fight guys.

Service department has been pretty good so far at my dealership. They got me an appointment for this coming Monday.

 

It took about 6 business days to get the rear axle assembly in, which im assuming includes defferential/ring&pinion/etc.

 

I will report back sometime next week on my findings.

 

Again, my truck shakes mildly between 25-30, steering wheel vibrates at 50-55 (especially when slowing down from freeway speeds), has a "pulsing vibration" that I feel in the gas pedal between 65-70 (feels like 1 second on, 1 second off small rumble strips), then has a back and forth shake once I get to 79-80, which is just like the video posted a few posts above.

 

Hope this axle resolves all these problems.

I had a complete axle replaced in mine and didn't change a thing... I think my truck was the 2nd to have an axle replaced here on the forum with no fix.. Maybe I received a 2nd defective one from the same batch of axles? Good luck my friend. Trust me I went through it all and my fix was trade in assistance from GM and a truck that was built 9 months later

I was just told by my gm deal ship the vibration is coming from the prop shaft ring and pinion. They can replace it the only question is how long till it starts again. I asked about tires they laughed and said that's what other dealerships tell people. They said there will be a fix in time but for now call gm and complain. The shaft is junk they can replace it 100 times and it'll still go out. They showed me a 2015 with 300 miles that's been sitting there for a month waiting for the right parts. Guess ill just call and tell them my vin and see if they ever fix it.

2500 miles in; 4.3L 4WD Sierra dbl cab. Now getting vibration for the first time, but it's different than what many of you are witnessing -- I'm having a really harsh rumble occur at 50 mph when the truck goes into AFM/four-cylinder mode. Truck did not used to do this when switching between 6 and 4 cylinders before; there was some change in resonance, yes, but not to the point of discomfort. Wondering if an engine mount might have gone? Anyone have anything similar?

I am waiting for a new GM truck commercial stating that "unlike the competition,whose trucks ride smooth, GM trucks vibrate, which is something a properly designed truck should do". What are the odds of seeing something like this on TV any time soon?

Mine has the vibration. I know there is no fix. Should I at least log a ticket with my dealership even though I know they can't fix it?

      By newdude · Posted

      Based on what I can tell, yes.   As for updating it, its a mixed bag.  Updates do fix a lot of issues, but occasionally can create some oddities.  They do more good than harm though overall.     Here's what the most current one does and a  V171 Improvements Important: Improvements will vary by model, build configuration, system, and sales region. Not all vehicles have all features.

      Front End Rattle

      By AndrewF · Posted

      Looking for help troubleshooting a metallic like front end rattle. Figured I’d see if anyone had thoughts before I schedule an appointment with the dealer.   The rattle is fairly loud and occurs primarily when the front driver side wheel hits a bump, even fairly minor road seams. Sometimes does it when the passenger hits a bump but I don’t believe when the rear hits. Rattle still occurs when foot is pressing brake peddle so I think that rules out the caliper rattle I’ve read about. I’ve also checked the running boards and they are tight.   Most noticeable at slow speeds.    Any insight is appreciated.

      We try to make cruise the coast. It’s where our favorite casino is. I only want to spectate. Never took a car. Always had one to take. I belonged to a club once. Even when I used to drag raced. It was during test and tune. Probably because I’m not a night owl, party person.

      Good looking Olds, and TRX!   I haven't been into car shows either. I'm probably not a convert but I did push myself this year to attend a few select events to challenge some assumptions and try to experience car-based social clubs in a different way. I joined up with the local Hagerty group for some cars/coffee events, group drives. A month ago I showed my '94 Camaro I rescued last fall at Radwood. Had a good time, but, there was some sitting around with the car and that's the part of shows I don't enjoy as much. I prefer to be a spectator, walk the show, grab a burger, go home.   Radwood was the only era-limited event, but where it had strict model year limitations, it made it up in variety. Having Jason Camissa there was also a hoot.   Where I see old 50's car shows, doo-wop and winga dinga music stuff fading out, same with "only" vintage muscle clubs, it seems to be the activity-based clubs/events which are gaining strong popularity. Places where all cars and interests come together.
