Shake or Vibration Issues

[Jesse Davidson]

Have you ever tried a different set of wheels/tires? Has anyone had the tire slipping on the wheel issue with the 20 or 22s? If your wheels are slipping in the tires that could explain it happening a year after the fact... If that's happening it's really ****ed up though...

Yes I own and have used both the 22's and the 18's it makes very little if any difference in the vibration

They know what the problem is. The problem with getting it fixed is that car companies are ran by business men and accountants that answer to share holders, and the price to fix it has not yet exceeded the price of ignoring it. Like I said until it hit's GM's bottom line they won't do anything. Expect to see 2016 owners on here within the next few months with the same problems going through the same motions.

so you're finally coming around to the "dark side" lol... I put a call in to one of my personal lawyers, and am waiting for a call back. I'm going to try to sue under Massachusetts Chapter 93 section A. she is currently reviewing the bill of sale and checking into what we can feasibly do.

Why not just lemon law ?

It's a vibration, how can it not be fixed?

[Bdkfl]

Mine went back in for the third repair attempt on Tuesday and I got a call today saying that they used the pico scope and determined the driveshaft to be the cause. From what I read on these forums that has never been a solution. Fingers crossed!

On our first 1500 Silverado they replaced ours and it did make a slight difference but did not solve the problem. We went through the BBB process and ended up settling on a 2015 Sierra and they've just replaced the shaft on this one as well. We'll be filing again with the BBB again shortly. Sorry - but for us and our two trucks the shaft didn't fix it.

I haven't tried different wheels & never marked my tires to check for slipage....

Mine vibrated with stock 18's and really don't think tires and rims are the problem they probably just contribute to the issue like the long list of other things . Hate to say it but I think it's the chassis and suspension design .

Just my opinion and observation . All the attempted fixes are just a bandaid to the problem it appears .

but why is it one truck out of every.. say 5?

[Badass69]

Exactly.... above me.. I had my tires swapped with BF KO2's in the stock 265/65/18 size at my local Ford dealership and they didn't care about balancing the rims on this truck any different than anything else. Truck had no vibration before and nothing now so it's not like it's every truck. I will say I test drove a Max Trailer crew cab with 20's and it vibrated above about 60 mph but mine doesn't do a thing. If it's inherent to the chassis design they would all do it. That and members having tires swapped and rear diffs rebuilt and curing the problem wouldn't occur either.

They just ordered a whole new rear end for my truck....Ill see next week if it worked

That's s very good question but I wouldn't be surprised if they all had it just some worse then others.

I mean, at 70mph I can see my passenger seat and center console shaking, gets worse the faster I go from that point... But no shaking in the steering wheel. Then under, say, 65mph, the truck drives like you're driving on glass. Just on my way to work this morning, I hit 60mph and held it there for a decent stretch and no vibrating. You wouldn't even be able to tell. Low speeds, same thing. No take-off shudder, no V4 shudder, nothing. Literally, once I hit 70mph, it's like a completely different truck. I've always had toyotas up until about a month ago, we still have a Camry, and I've never had an issue like this where I didn't know where it was coming from. I mean, when you lift trucks, you can tell the tires are out of balance, etc. I had a shudder in the center bearing of the two-piece driveshaft in my tacoma, that was fixed when I shimmed it back down after the lift. idk...

Why not just lemon law ?

Because I refuse to own another GM product (with Lemon law, you basically get a newer GM, that in this case will likely still have issues), and like some others here, I got an insane deal on my truck and never be able to afford a comparable truck under Lemon Law. The fact that I got a good deal from my dealer doesn't negate the MSRP value of the truck, which is being severely compromised on the trade in value because other dealers know about this issue. I went to try to trade my truck in, and was offered over $12,000 less than what it should be worth according to the book value. I will not take that type of hit because GM can't get their sh*t together, and legally I don't have to.

 

In addition, i have her looking into separate cases for fraud and deceptive business practices.

 

I'm not someone who puts up with bullsh*t, and have absolutely no problem taking any legal action when I feel it is necessary

 

It's a vibration, how can it not be fixed?

Some can be fixed. Its a combination of alot of different issues. The main one that transmits the vibration is the body frame mounts, engine mounts etc. that were improperly designed. This will never change because GM would then be forced to run the vehicles through all of the crash safety tests, and any other government tests at an immeasurable cost. Plus after that they would then be forced to issue a massive recall to replace them all.

 

the "High Strength Steel" also transmits more vibration through it, so we now feel that even more.... again will not be changed

 

The new method of cutting the gears in the rear diff is a 2-step process vs. the old 5-step process, they are being poorly manufactured, again can be fixed, and for some it has, although you find people like I believe it was abominable who found the teeth on his to be chipping.

 

Some have exhaust resonance issues, could be fixed, mine was... sort of... it was previously cancelling out some of the frequency in the normal vibration, those are now evident [My opinion and theory]

 

This is not confirmed, but I believe that there is some misalignment in the rear suspension, I am seeing more and more people saying that their rear shocks are shot, could be poor manufacturing, but to each his own.

 

Mine vibrated with stock 18's and really don't think tires and rims are the problem they probably just contribute to the issue like the long list of other things . Hate to say it but I think it's the chassis and suspension design .

Bandaid is correct... I have ZERO faith in GM anymore

 

not to mention their Chevy Customer Care is no more than a therapy hotline to make you feel like you have some control, The dealers and the regional reps outrank them, They can't do sh*t for you

 

Rims are not the issue

My steering wheel shake is the worst of it all. The rear seems settled down but steering wheel is irritating. I can actually feel the steering wheel vibrate at idle in drive. I think it may be motor mounts needing shimmed but waiting to get into dealer.

Mine is the same way, except up till 74 it drives smooth as glass. About 76- 79 is the worse shakes. Not sure if I wanna pursue taking it back and forth to the dealer or trading it in

[hotrodz37]

The biggest problem with this whole issue is that they are replacing flawed parts with flawed parts. GM orders a new rear end to replace one they deem "out of spec" who's to say the new one isn't out of spec as well? The only way to really figure out the root cause of the issue is to replace rear end gears, drive shafts, etc with parts from manufactures that are the most well known/reliable in their fields so to speak and not replace GM garbage with more GM garbage.

[yahtzee]

No way would I ever trade in this vehicle (or any vehicle for that matter). I too got a great deal on my XL Denali. I also received a decent "we are sorry for all of the shop time" payment from GM along with a healthy accessories credit (that I was going to spend anyway). I made it very clear that that was for issues to this point and that I still expected them to work to solve the vibration and buffeting. Unlike some, I am not dropping off my truck and letting it sit there until I see some type of traction being made here (like the two links showing the vibration fix for tires and drivetrain...They are working with me as best they can and because there is NOTHING that remotely comes close to this vehicle in comparison, I am sucking it up and hoping for a fix. Caveat - had a purchased this vehicle and not leased it I would have walked away after the first two weeks of troubles.
