Yes, bad tires or incompetent balancing seem to account for a good percentage of these problems. My local Chevy dealer service manager told me the same thing - that it is mostly tire problems, but also differential and drive shaft problems.

 

I wish we had statistics from GM on those trucks that were successfully repaired under warranty to see what the percentage distribution is. This data would also help people see what are the root causes and possible solutions to these problems.

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

Well I have some good news and bad news about my truck vibrations. Good news is that my truck has a significantly less vibration at speed. The bad news is my truck has significantly less vibration. Fo

I'm told my truck was successfully repaired!

Do I believe it? No. But I do have a glimmer of hope as I sent one of my guys (who isn't as in tune with these things as I am) to pick it up and he said it's good as well as the head service mgr who I've delt with since day one and has drove it with me 4xs.

So now the "explanation"...

So they started where they all start. The tires. Road Force revealed some abnormalities, exact readings I'm unaware of, but adjustments were made. They drove the truck and still detected vibration with the GM vibration detector and their butts. They went to the rear tires and re balanced them on the "NEW" laser balancer and found nothing out. Remounted the wheels, drove it, was worse. The tech simply rotated the rims on the studs 180 degrees and drove it again. NO VIBRATION!

 

What the hell? So now the theory is the hub centric wheels don't mount perfectly everytime or could be sensitive to even torque during installation. The dealer believes the wheels them selves could be the problem. Being the second set, it could be a manufacturing issue.

 

Thoughts?

I'll be to it in an hour or so to give it my full assesment.

As soon as i took those shitty azz tires off my truck its been smooth as can be. Ive got 12k on it and still ridin smooth. The other day i was coming home from BPS and i decided to take the highway to see if my vibration had came back... Nope, smooth all the way to 85. I'm not saying tires will fix everyones trucks, but im sure glad i didnt screw with the dealer on my 2nd go round

 

$1200 and four Michelin LTX M/S2s later, the truck rides smooth all the way to 85mph (where it is actually legal to do on a tollway in my neck of the woods). Too bad GM doesn't consider doing this on their highly marketed Denali line from the get-go.

 

In my humble opinion, the GMC dealership I ordered this truck from can go eat a bag of d*cks. I am done with them.

Anyone read thru other forum threads on here and notice a commonality. There always seems to be the off topic comments within those threads about vibrations. For example I was reading a catch can thread where someone happened to mentioned a vibration and wondered if it was from the can mounting then others chime in about their slight pedal vibrations as well but stating they noticed theirs before the can install. So these vibrations, some much more pronounced than others, seem fairly wide spread.

This thread gets a lot of mentions on other sites too: "There are several causes, some get fixed but most don't. There are over 200+ pages on gm-trucks.com on this topic"

MY VIBRATION IS GONE!

All the way to the governor. I am wondering if I'll have this problem every time I need the tires balanced and/or wheels removed. I'm sure there are many reasons why these trucks have problems but I urge you to find a good tire shop.

Mine actually came with them...

You will like these tires, sucks you had to fork it over yourself. They'll last 40% longer and give you superior wet weather traction, just wait for the first time someone causes you to slam on the brakes in the rain. Glad your riding smooth! Others are not so lucky to spend 1200 to see a fix...

I wonder how many people have had the body mount service bulletin applied (repositioning and retorquing) on their trucks and whether or not that led to a successful fix.

its hard to find out anything when GM refuses to work on my truck. I have been told time and time again that it is working as designed. It vibrates as bad as it always has.

Question - are all the wheels on the 2015's hub centric, including the 1500's and the Tahoe/Suburban/Yukons, or just the 3500 dually's? I've got the issues on the "noise" thread over in the SUV section of this forum and wondering if my Yukon also has hub centric wheels. (Which in theory are supposed to be perfectly entered, as long as the hub bore isn't too large or the hub too small!).

To the best of my knowledge, yes...

 

I feel like a little kid with a big red button in front of me, I'm dying to take one of these off and see if there is any play in the wheel without lugs but I'm not willing to jeopardize my ride quality. Maybe when it's due for rotation and balance I'll investigate.

 

I personally am not buying the fact the the hub bores are to large. I feel the most likely scenario is that the tech hangs the wheel on the studs then hits it with the impact to tighten the first lug nut, it's possible if the hub bore is to tight that it causes the assembly to get bound up and not sit flush. Maybe asking them not to use pneumatics on install would eliminate this variable? I don't know... I'm just glad they fixed it and dread the next rotation and balance!

I know I wouldn't mess with mine if it was OK!

 

I agree there is more chance it's an assembly error, not component defect. Especially if hub-centric is a new thing. Someone didn't communicate properly to the line and next thing you know, it's being done wrong. Wouldn't be the first time something like that happened. And you're right - they have no fricken' business using impact wrenches to put wheels on!

I'm still having shake at highway speeds (typically 72-83). Tends to taper off at about 85, however still doesn't feel FIRM. I hate this and it ain't the snow because I purposely cleaned my wheels the other day to get all snow and ice out before my recent 2hr road trip.

      Towing In Loose Gravel

      By KARNUT · Posted

      First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move.

      Towing In Loose Gravel

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.
