Shake or Vibration Issues

Have you brought it to the dealer ?

Yeah, haven't had time to go back again. They road forced the tires and it helped for about 10 days, then it came back like it never disappeared

Unbelievable

so....my truck, 2014 Silverado, double cab, 5.3, 3.42 rear z71 - vibe issues on highway - been to the dealer many many times, changed shaft - changed tires - changed shocks - then shimmed and changed pinion/shaft angle - ... changing the shaft angle helped with the highway vibe, but created a launch vibe - and it was pretty bad( under a heavy foot) - keys would rattle against the column. even worse with a load on the hitch - since im not actually on the highway much I asked a different dealer to put it back " to stock" although the original dealer who shimmed it said the were shimming it to put it " in spec" and they were big shims - so...... launch vibe gone - highway vibe back - and noticed something - at 40 mph or so I have another vibe - a vibe I thought was v4 drone( was there when I originally bought it) - but obviously its not, cause it didn't do it the whole time I was shimmed - and now its back - some seem to be fixed with certain things- but think mine is a drivetrain alignment problem - like a cross member is off a hair from the trans or engine - just wont seem to line up - my 2 cents and experience -

Did you talk to the dealer about a buy back ?

It has been discussed but not pursued. There is nothing else even close to it on the market. I am just hoping for a fix.

Should have did a little more research before buying this truck but hopefully Chevy can fix it. Going to drop it off today.

I’ve driven the truck approximately 1000 miles on all types of roads. From 40 to 55 the truck resonates (vibrates), especially when decelerating, and going downhill. The more you drive (warn up the vehicle) the worse the vibration seems to get. I can feel it mostly through the steering wheel but can see the dash and center console vibrating in the truck when it’s really bad. I say resonate because it doesn’t seem to be the tires although I really can’t tell. Never had tires vibrate like this before. When driving highway speeds 60 to 75 the vibration is less noticeable (tolerable) but still happening. Almost seems like the driveshaft is out of balance or a bearing is going bad.

I've read through several reples and different sites has there been any specific cause for this problem or is it different for every truck?

They can fix it or buy it back if they can't , but only if you are persistent enough to force them to do it.

Wow, how many posts and still no cure, I'm raising the white flag. GM doesn't need my future business.

I am pretty sure mine is fixed. Take a look at my last post detailing the repair.

I have put on 250 miles since Thursday and will put on another 200 tonight.

Same here about 1k miles after who knows how many tires and RF balanceing. Thats all it took for me.

LongrangeLauber · October 18, 2015

If these trucks are so sensitive to tires, what's gonna happen when you need another set and have to keep going back for RF balacing? Or is it just because the dealers/ manufacturer gets second rate tires on the cheap?

I want some Michelin AT LTX tires or BFG KO2. The only way I would buy these tires now is if I had a second set of rims. There is no way in hell I would swap them out at this point.

There was no preload on my pinion and I think that was the main issue. I would suspect that the rear differential machine that sets these up from the factory is messing up in production. Not only was my preload wrong, they also used the wrong shim behind the pinion bearing. I highly doubt that these are done by hand anymore.

The guy that setup my rearend at the local dealer has been doing this for 25 years. You don't just throw in a ring and pinion. It is a very precise process. I set up two 12 bolts for my chevelle with an old man that had setup 9" ford and 12 bolts for years. Only after about taking the carrier out about 10 times did I get the pinion depth, pattern, pinion preload and carrier preload set right. (on the 12 bolts, not in my 2014 sierra.) The process had to be very similar though.

My point is if you don't get a seasoned vereran resetting up your rear differencial at the gm dealer, it could very easily be messed up.

Oh yeah, that's one thing I wouldn't mess with is setting up a rear end without an expert involved. I just pay the 400 an axle for my mechanic at my off road shop to do it

For the couple guys that have theirs fixed, mark your tire and wheel at each one. Mine was "fixed" on Thursday and I marked mine. After the ride home and towing the boat, I have one tire that has slipped almost 10" on the rim, and another just over an inch. Both rear tires. Can't believe how much it slipped.

I'm gonna mark mine before I go into work tomorrow and drive aggressive on the way to work, see if they move. Maybe the wheels are just a tad too out of spec to keep the tires from slipping on them.

Maybe it's just all this raw GM power I'm putting down... lol
