Shake or Vibration Issues

jeffziss · December 13, 2015

The challenge is that there are so many different issues. Anything from differentials, to driveshafts, to u-joints, to shocks, to chassis issues, to tire/wheel issues. GM just doesn't have an answer. Unfortunately for those who have purchased the GMC equivalent vehicles, they have the issue and it apparently impacts the SUVs as well.

Will do!

Yes. I just posted that my 2016 has the exact same vibration that my 2015 had. I also noted that I had to drive 6 trucks before we found one that didn't have the vibration. Unfortunately, after about 40 miles it had the exact same vibration and I'm stuck with it.

thats unfortunate

All,

GM was great. They agreed to do a $5,000 trade in allowance on my 2015 Silverado 5.3 DoubleCab 4X4 LTZ. The truck had 4,000 miles on it and the vibration was unbelievable. It would make my wife car sick. I had to drive 6, yes 6, 2016s before we found one without a vibration. I ended up "eating" $7,000 to get into a 2016 but I felt it was worth it because I had a $48 (sticker price, not what I paid) truck that my wife couldn't drive in. 40 miles on the truck and it has the same nasty vibration from 70MPH and up.

All the dealer wanted to do, was keep road-force balancing the tires. I thought it was ridiculous. Rather than wait weeks for an appointment, I paid $2600 for new aftermarket rims and tires and I'm stuck with the exact same vibration. I am now $10k into this mess. Do yourselves a favor and warn people.

I have started this website as an attempt to protect others from buying a Silverado. It will take a couple of days before it is up.

Definitely doesn't hurt to have more visibility for these issues, thanks. Not sure if you saw the posts or not but I have a 2016 Yukon XL with identical vibration issues. I since started a FB group ( reached out to approx 10 auto rags about pressing GM harder for more eyes on these problems. I actually had one of them write back and pursue it. Now, a story will be dropping tomorrow (Monday, the 14th) highlighting the vibration issues as well as the buffeting issues lots of GM large SUV owners are experiencing. I am 4 months into this ordeal...GM has been little help but my dealer has been fantastic. Thanks for helping with additional exposure!

I have a thread in my banner for a lawsuit I'm working on against GM for these issues too!

Jesse - I included a link to your thread on the website I have just launched.

Yahtzee - please PM the FB page and I'll include it on the website. Also, include the name of the magazine, that is writing the article, in the PM. I'll post it on my homepage.

Video of my vibrations at highway speed. Road is smooth. It's a longer video but I want to document it for my dealership.

I was with my buddy the other night coming back from dinner going around a bend about 55mph when the truck shook like crazy. My vibrations and shakes have never been that bad until then, and I can't recreate it. I'd imagine it was similar to what many of y'all experience in terms of how bad it was. Even my friend was like "what the hell was that, is your truck falling apart?" I couldn't say no for sure though [emoji23] [emoji23]

Well my last attempt at eliminating the vibrations or at least stopping them from getting into the cab may have been successful. Two days in so far and they have yet to return. I'm sure everyone wants to know what did it... I installed a zone 1.5" body lift. Whether the body mounts were allowed to "relax" when the body was lifted off of them, or the space created between the body and the rest of the truck eliminated a ground path that was allowing the vibrations to transmit into the cab I couldn't say for sure. All I know at this point is the steering wheel, seat, center console and gas pedal vibrations are gone. A few more weeks will tell for sure whether they're gone for good. Anyone that has followed this thread long enough like Jesse D and Bill and a few others know I have basically dismantled this truck trying to find a source and never could. Maybe the problem is the body mounts themselves. Unfortunately most people probably don't want to put a body lift on their truck nor should they have to to eliminate the vibrations. It's been said quite a few times on here that GM needs to look at their body mount design, I think this just reinforces that fact. That last thing I had done on this truck before putting the body lift on to try and find the source was to have the wheels balanced on the truck. Fortunately there's a shop here in town that does it and there wasn't any vibration and the balance checked out fine. Whatever is causing these trucks to shake the problem is the mounts are letting everything into the cab.

YES!!! You sure as hell have dismantled that vibrating box on wheels. I had the info about the mounts from an attorney I spoke with. Once someone here brought it up, I said they were right (per the lawfirm) if anyone here remembers the Vibration TSB that was posted, lifting the bodies off the trucks momentarily with a pry bar was the solutions to one of the causes of Vibration. it said the mounts "settled", and allowed the transfer of vibration. I would guess that adding a lift would help to alleviate that, atleast for a time. I personally have no interest in putting a lift on this truck. I got the 22's to be a street truck, If I wanted a lifted off road truck, I would have gone a different route.

EDIT:

As a side note, I was at the dealer yesterday for my free 6,000 mi oil change, and asked the service writer to see if there have been any updates to any of the vibration issues. He said that the 2500 & 3500, now have a TSB to add some type of dampening system to the steering column for the AFM Vibration that they experience.... I asked why the hell they didn't do that to the 1500's, he didn't have an answer....

This is it post body lift. Same wheels and tires no other mods done, vibrations gone.

Keep us posted! I would certainly consider adding a body lift if it helped the vibe. I have been looking around at different truck brands but to me, the gmc's and silverados are the best looking trucks on the road and I like mine as long as it's under 72 mph. Would be great if this winds up taking care of it!

How much different would a 1.5" body lift look than the 2-2.5" leveling kits we are all putting on now? How much difference is the cost, and is there anyone that makes less than a 1.5" lift?

Post 6896 is a pic with the truck leveled with the body lift. Rough Country makes an 1.25" but I think the method to raise the bumper in the rear is a PITA with the RC. As it is with the zone 1.5" the bumpers are a pain in the ass, but it has to do with the way they are assembled from the factory. If you're going to put a body lift on yourself make sure you have a sawzall and angle grinder with a cut off wheel. The amp power steps present their own difficulties because of clearances, factory steps wouldn't cause an issue. I had the advantage of already taking the front and rear of this truck apart to install the grille and the sulastic shackles in the past. If anyone has questions regarding the install of the body lift feel free to hit me up.

I'm going to monitor it throughout the week, I drive the freeway everyday and the speed limit is 70 so I often do 75-80. I'm also going to take some vibration readings using my phone like I had done in the past and compare the readings now to the previous analysis. Fingers crossed they don't return, but I'll keep everyone posted either way.
