Shake or Vibration Issues

Just got an email from GM, they are finishing up processing the paperwork in the next couple minutes. The close date is being scheduled for 5 Business days from today, so I get the Denali is 7 days.

Jeezuz, this is just like prom night, the anticipation is killing us! Good luck, and I hope the first shaker has not set your vibration sensor to ultra sensitive! lol

I can definitely say that I have felt it to a much lesser degree in every 2017 GM truck I have driven, so I can say right now that it won't be as smooth as it should be, but will still way way way better than my 2015.

Hi everyone.

I joined to add my truck to the list exhibiting the Chevy Shake

 

I picked up this 2016 Silverado, LTZ Z71 with the 6.2l. Beautiful truck, inside and out, but dang does it vibrate on the interstate! I bought it CPO October 25th with 9200miles on the odometer. After the first trip out of town I couldn't believe how bad the ride was. I felt really bad for my kid in the back seat being shaken up for 3 hours each way.

So I brought it to the dealer and they told me even though the tires road force balanced to less than 12lbs each, one of the tires actually looked out-of-round and they replaced it. The new tire road force balanced to less than 4lbs.

Fast forward two weeks and I'm back on the highway, bouncing *almost* all the way up north. I have video that I've shown the service advisor and he seemed to admit some of these trucks exhibit this problem. They're getting it back tonight before I fly out for the remainder of the week. I'm hopeful (but also doubtful) that the issue will be resolved this visit.

General description of the symptoms on my truck: Minor and inconsistent vibrations from about 45mph - 65mph. Sometimes it is noticeable, other times I can pretty much convince myself it is road conditions.

Major vibrations 70mph+ to about 82mph. Oddly the vibration is worse BY FAR on smooth, new concrete. Old patches of road with expansion joints/defects/etc seem to tame the vibration considerably, though I can of course still feel the road problems.

 

I'm coming out of a Porsche Cayenne Turbo due to it's frequent need for dealer visits. Man would this be ironic if the Silverado has to keep visiting the dealer too.

 

Anyhow, I'm glad this thread exists at least for my own sanity. Can't make this stuff up.

Crazy! Those are my issues exactly! Vibration between 70-82 and it's worse on smooth roads. I'm taking my truck in to a driveline shop this Saturday. They are a very respectable shop. I'll see what they say. Hopefully it's just a bad driveshaft. Keep me posted on what they tell you. 3 dealerships ive gone to. They were all useless. Edited November 16, 2016 by EspoMan

What was the history of the truck? If you haven't done so already, ask the dealer for a warranty history report. I'd bet you'll find a bit of information regarding the previous owner's attempts to fix the problem.

Just curious but what kind of issues did you have with your Porsche?

Good suggestion. When we came across what looked like a fantastic deal, I was trying to figure in my head why someone would trade a truck like this after only a few months and 9k miles. I decided it must have been grandpa's new truck and he could no longer drive, or perhaps a repo. I guess I have a pretty good idea now, but a history report is a great idea. This truck is replacing the duties of my crappy (but trusty) old '93 sierra for utility, and the Cayenne for family trips & DD.

In my mind, these symptoms do not fit a tire/wheel out of balance issue. I've had that. A wheel out of balance doesn't come and go depending on road surface, nor does it change in intensity like this. It is most similar to when my Porsche had the driveshaft center support bearing bushing torn/beginning stages of failing. Match-mounting and road-force balancing tires/wheels minimized the effect on that car too but replacing the center support bearing was the magic bullet. Please do share your results. I'll do the same, but it'll be early December before I'll have the need to be driving out of town again.

Off topic, but it is an 04 with 180k miles. It has had EVERY documented issue known to the rennlist and renntech forums (several more than once.) I've been fixing them all as they happen, but decided I'm in a position to enjoy a new truck that won't need to visit the shop all the time. Ha!

Just got an email from GM, they are finishing up processing the paperwork in the next couple minutes. The close date is being scheduled for 5 Business days from today, so I get the Denali is 7 days.

Let us know what the driveline shop says. Mine is going in to the dealer in morning for load balancing. I seriously doubt this will improve the vibration issue.

Yeah no problem. I will definitely keep you guys posted. I am hopeful, since mine is not AS bad as some people here. I'm gonna tackle the steering wheel vibration next. It's minor but drives me nuts.

[14silverado4.3]

I tightened down then loosened the transmission mounts, 60 to 15 to 32 foot pounds.

Drove around for a few days with 60 foot pounds, although stiffer - horrible as you felt it all

Vibration from the rear was felt a lot more.

 

Back down to 32 foot pounds and the vibes are less.

 

 

 

 

Has anyone replaced the transmission mounts.

Ladies and Gentlemen,

 

After 35 years of GM vehicle ownership, I recently traded in my 2014 Bouncing Betty (yes she had the vibration / bouncing issue at 70 and a ticking noise with less than 24 thousand miles) and purchased a New Nissan Titan XD. Yesterday I was driving in Michigan, where the speed limit seems to be 85, when all of a sudden I realized that I was doing 85 and there was no vibration or bouncing. WE need to file a class action lawsuit! I really want this fixed, I want to be a GM owner again. My Nissan has done nothing wrong - No issues at all - but I still crave the Chevy look when I drive by. GM knows what the problem is - WE need to force them to fix this issue! It is time for a class action lawsuit.

Jesse tried to get numerous Lawyers to take a class action. They all declined, they're not interested unless the problem has killed someone.

Jesse tried to get numerous Lawyers to take a class action. They all declined, they're not interested unless the problem has killed someone.

Which, of course, is ridiculous because there have been plenty of class action lawsuits for silly things that didn't kill anyone like extra fees being charged on cell phone bills or improper medical insurance billing.

I figure it again is just not widespread enough for there to be any money in it. A lawyer won't take a case if there isn't enough money.
