I honestly think the problem has nothing to do with the running gear. I'm willing to bet all mfg's have the same tolerance level when it comes to NVH. It has more to do with the fact that Chevrolet is not isolating the problem like it should be.

 

Fix this you'll fix the shake. Look at it this way; you can put cement cab mounts on the truck and it will ride like dog crap. Now you can say it's a wheel balance, driveline, rear end, or a plethora of other things, and you'd be correct to an extent; but no matter what you do, it will still ride like crap with cement mounts.

 

Chevy needs to address either the front suspension, cab mounts, or both IMO. Isolation will go a lot further than trying to systematically track down every little vibration.

At this point after months of measuring run-out, RF balancing everything multiple times, match mounting, trying different shocks and so forth I agree the problem is isolating the driver from the vibrations. High strength frame and high strength steel body make great conductors for the vibrations. The million dollar question is why is it so much worse in certain trucks?? I've ridden in my co workers 14 silvy CC and its vibration free. It's like everyone is saying, a lot of parts at the top of their tolerance and an unforgiving frame and cab. I took a 15 ram laramie 4x4 cc out for a test drive and while it was smoother, it wasn't vibration free either. I wasn't wowed by the truck to the point I was willing to trade mine in on it some other members are claiming night and day difference and glad they traded out but that wasn't my experience, it has features the GMC doesn't but the same is true for my SLT, it has features Ram doesn't offer as well, and IMHO the GMC is a much better looking truck inside and out.

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

Not sure what the deal is, the .jpg link is broken for me...but hopefully you got nothing short of full MSRP trade. That is what I got, and what everyone should get when trading in a lemon.

 

That is what GM does. They offer you 2 crappy deals, maybe a third, then the arbitration date is set...and a day or 2 before arbitration, you will get a call saying they basically give up, and will give you full MSRP trade. Accept nothing less.

Ehhhh.... Sort of. I didn't get offered MSRP as a trade but because the District Manager assisted with trade assist, the fact this was one of the 20% off trucks and then the dealer took off the dealer hold back/mark up, it worked out. Was it an even trade? No. Am I currently happy, 99% yes.

 

I couldn't being myself to go thru the process of switching brands and frankly, I like the Sierra's the best, so....we will see. So far, LOVE the space of the crew cab and the new truck smell.

Well my truck has been at the dealership for a total of 32 out of 113 days owned with vibration issues. So far I've had a set of rear tires replaced, two full sets of front tires (1 set with 150 miles and another with 350 miles put on them), replaced rear shocks (supposed 10mm dead space in one shock), balanced and rotors, checked specs on ring/pinion, replaced rear driveshaft......AND....to no one's surprise it still shakes. Howwever, the shake has changed and gotten worse. From 0-60 truck is great. 60-68 smooth but vibration starts coming in. 68-75 very noticeable vibration in steering wheel, seat, door panel and now the pedals. 75-90 you better hold on its gonna get rough. So to really see how bad the issue was after I test drove it, after it was supposedly fixed from the dealer and passed on the pico, I took my foot off the gas and naturally let the truck decelerate from 90 to 60. Wow is really all I have to say. The truck now seems to have a deceleration vibration that is even worse.

 

As of now it shakes while accelerating from 60 to 90 and shakes just as bad coasting from 90 down to 60. The Service Manager is at a loss for a solution and shocked. Supposedly the regional GM rep will be looking at my truck this coming week. I can only hope I have the end result as some of you other guys with an MSRP truck exchange program.

 

I'll keep everyone posted. I'm hoping they make it right so I don't have to go through the BBB. Any advice or direction would be greatly appreciated.

This is getting insane. Money and time wasted on the same remove and replace this, that and the other part over and over again with no positive results. It would not surprise me if GM decided that the real fix would be to return to the 55 MPH national speed limit since they seem to have gotten nowhere after all this time. What's that saying about repeating the same thing expecting different results?

I'd chock it up to mfg tolerance differences. Another thing to note is; the trucks that were the worst had 20" and larger wheels. My truck has 22's and the two High Countrys I drove which were almost as bad had 20's. Bigger wheels and lower profile tires lead to less absorption of road anomalies before being transferred to the suspension. This is just an educated guess on my part, but I'd wager to be on the right track.

 

Keep in mind also; most people might not even be akin to the vibration unless it's pointed out. One of my employees has had his truck for 5,000 miles and claimed it's perfectly smooth. I went out and drove it and it also exhibits a shake; albeit minor. After pointing it out, it's now driving him crazy, lol.

Very possible that some may not be akin to the vibration. I have a '14 Sierra crew 2 wheel drive with GM 22's and it's vibration free. I've taken it up to 90 and the water in my bottle was not jumping around. I have a savvy for noises and vibrations. A co worker has a '14 Sierra with 20's and I rode in his and it was smooth as well. I have no clue what's causing the vibration as some have had it corrected with tires, balancing and some haven't. Different combinations of things I guess. Some 14's have a vibration some don't. Some 15's do and some don't. I feel for you guy's having vibrations. When you spend that kind of money on a truck, this shouldn't be an issue. Wonder what the new 16's will be like? The front end cosmetics have changed but I'm sure it will be on the same platform.

Ok so after visit 3 it seemed better. Took a 3+hr drive to Ft Wayne IN. I now have a constant low dull vibe under my butt in the seat almost numbing after a long haul. No more console shake though. Much more pleseant but still not fixed..... calling the lemon lawyer Tuesday for sure now.....

My girlfriend got my truck on the highway today and called me because she thought it had a flat. 2014 Sierra 22000 miles. She says she there's a vibration above 70mph. I remembered seeing this thread but hadn't had it on a smooth highway for an extended period of time yet and didn't know if my truck was affected. I drove it today and confirmed that it vibrates. Not horribly but definitely enough to annoy. What are the odds on GM fixing this?

      New to Me 2010 SLE (Quirks, Issues)

      By davester · Posted

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
