It's hardly at random. The driveshaft issue is something they have already seen a few times and well know enough at gm that the design has already been changed. They have also done most of the things you mentioned. Inspected all the gears, bearings, ujoints, checked for tolerance issues in the gears and the contact pattern. Inspected and checked tolerances on both drive shafts and everything looked normal. Replacing the entire rear end was a decision made outside of the dealership by whomever at gm they contact for advice.

I had the same issue with my crew can, dodge, Chevy and fords. Roll down your back window a little to break the air vacuum that's created. It should silence the thumping noise.

 

Tried to quote a post but it didn't work. This is on response to the front windows down and the noise associated with it.

Aboothlsu what was your build date of your truck. I am having issues similar to yours.

My new truck is vibrating and the driveshaft is making noice. Tires have been rebalanced, did not fix the problem.

Had 3 of the 4 tires replaced for lateral run out " wobble". I put my tires on from my last truck that ran very smooth and vibration is better, but not gone. Driveshaft makes noise and there is a weird feeling at rear of truck. My driveshaft makes a very loud noise when going from forward to reverse gear a lot louder then any truck I ever owned.

My fm signal from my radio is droping out and loosing station, makes static from wipers motor too.

My drivers lcd went blank for a second or two then came back, this only happened 1 time so far.

My fuel economy is not what it should be, and my trucks throttle response has delayed the transmission a second or two when I was turning left at a light. This has happened a few times now and I can not trust that the truck will go when I need it too in this situation!

 

My truck is 2014 sierra all terrain z71 4x4 crew 6'-6" box.

 

My dealer can not be trusted, as they lost this after telling me my truck is preforming like GMC intended,.

All those that are having problems need to contact their local state, province, or government agencies that cover vehicle safety or road safety and report these unsafe issues now until GMC is forced to fix before some of us get killed by these defects.

build date is on the inside of the drivers door on a tag

Trucks currently at the dealer. I don't remember what it is offhand. I have to call them and have them take a look.

 

I've also finally read through this entire thread and it seems a lot of people have went through multiple tire changes, balancings etc. some fixing the problems, others no luck.

 

I'm not sure why the dealer hasn't even explored this option only relying on the fact they rebalanced all the tires on mine over a month or so ago when I first came in for the vibration issue.

 

I'm not sure the tires have ever been road force balanced and I haven't received any new tires. I'm not sure they have even considered either of these options before jumping to trying new driveshafts and now a complete rear end assembly. If they have they haven't mentioned it to me.

 

Is it possible that a bad set of tires, not properly balanced, or road force balanced, or this combined with the vibration issues caused the blowout. The tire lost all pressure instantly due to a tear in the sidewall coming around a sharp 180 degree turn when switching interstates on the highway, when there was high lateral loads.

 

I've asked this question and they claimed it was in no way related.

Well GM decided to do nothing and not help me out. So sorry guys and F you after 30+ years of nothing but General I have gone to the dark side. But hey it's smooth.

So I get the feeling this will be one of those issues that they never admit to or find a fix for. Has anyone successfully lemon lawed one of the new trucks due to just the shake and vibration? class action suite we could all start to get this taken care of? I have driven it for almost 2 months and 2000 miles and it drives me crazy on the interstate.

Is there a video anyone know of that shows what the vibration is that people are dealing with? Mine has a slight shimmy in the seat at between 75 and 85 mph but if I set the cruise control on at 70 to 72 mph I get a very nice ride. One thing I have noticed is that these trucks are air sensitive, meaning maybe a slight chande to the exterior could give you a better ride? I wonder if any of the guys that removed the from air dam have better highway ride quality? A bug guard could make a difference ...I've seen strange things happen with water on my hood at different speeds, just wondering if something happened in the ole wind tunel at GM.

 

Has anyone who changed tires had this problem go away. By change I mean pulled the GY's off and went to a good tire.

I have the same issue with my 2014 Z71 4X4.... Vibration starts at around 70mph. Dealer road forced factory tires and rims as well as Discount Tire. After all that still have vibration.....

 

Truck at dealer for 3 days and now we switched to Michelin's and road forced those prior to install and STILL have the same vibration.

I am convinced this is not a tire issue. GM engineers are just lost on this one.

 

Anyone finds a fix please pass it on!!

Shakin Chevy...... Still no reply from GM or the dealer after filing a claim with GM over a month ago. New 2014 Chevy Silverado shaking worst than ever. I have owned over 10 new chevy vehicles but I have to say this will be my last mistake with them.

    • 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?
    • 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.
