Have you checked driveshaft also.

Yeah, I've replaced mine with an aftermarket aluminium unit. Put 150 miles on the truck today with the spare in place of the offender, amazing to finally have the vibration gone.

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

Hello Everyone,

 

I recently traded in my 2008 Sierra Denali for a new 2017 Sierra Denali which I’ve had for about two weeks now. The truck is a 4WD short bed with the 6.2L/8 speed and has factory 22” wheels with the Bridgestone Dueler AT tires on it. I have been noticing a vibration/shudder/rough feel which is felt mainly when decelerating under 40 mph all the way down to a stop (it is not brake related as this happens with or without braking). It feels like it is coming from the rear of the truck and can be felt throughout the cab. When I shift the truck into neutral when it's doing this it's perfectly smooth. I did mention this to the dealer and they wanted me to drive it for at least 500 miles and that is where I’m at currently. Just trying to get an idea of what may be going on here and causing this. Any input would be greatly appreciated.

 

Thanks

Sounds like the pinion angle is getting out of alignment or the rear gears are machined wrong.

Axles didn't help me. Found a bad wheel though. Which is odd since these were mounted on my Tahoe before I put them on my truck and I never noticed any vibration. Had the wheels balanced multiple times, no issues with a static balance had them balanced twice in the last 6 months without issues. A dynamic balance might solve the problem. Most likely will just replace them.

 

Good luck everyone!

What made you think to look at that particular wheel?

Did you check the Axles? I am pretty sure another poster has pinned it to the Axles......

Actually since I know you haven't read all 706 pages of this thread because if you did you would know that my vibes came from the stock driveshaft that was bent. I did true my axle flanges because they were not running true and did contribute to some vibrations just not a much as the drive shaft.

You go back and beg for your 2008 back, just like me.

Not sure if this has been posted or not.... interesting read if you haven't seen it before.

Very interesting! My first impressions when I first had the vibration start. Only variables i have is that when the truck was new it didn't vibrate. Very soon after within 100 miles of lifting it with bigger tires it started. I assumed pinion angle first and then wheel balance and so on... So Im wondering if this issue has a way of becoming a problem over time. Meaning the adjustment gets out of spec on its own. Ive been wanting to re-gear to 3.73 to compensate for the 34" tires and i might have them go over everything and see if anything else is out of spec. Another thought i have is the locker malfunctioning at higher speeds. Who knows

I didn't check my pinion preload when I did my gears but I can confirm there was no carrier preload, but actually slack that needed more shimming.

      Fred was in the fertilized egg business. He had several hundred young pullets, and ten roosters to fertilize the eggs He kept records, and any rooster not performing went into the soup pot and was replaced. This took a lot of time, so he bought some tiny bells and attached them to his roosters. Each bell had a different tone, so he could tell from a distance, which rooster was performing. Now, he could sit on the porch and fill out an efficiency report by just listening to the bells. Fred's favourite rooster, old Butch, was a very fine specimen, but this morning he noticed old Butch's bell hadn't rung at all! When he went to investigate, he saw the other roosters were busy chasing pullets, bells-a-ringing, but the pullets, hearing the roosters coming, would run for cover. To Fred's amazement, old Butch had his bell in his beak, so it couldn't ring. He'd sneak up on a pullet, do his job and walk on to the next one. Fred was so proud of old Butch, he entered him in the City Show and he became an overnight sensation among the judges. The result was the judges not only awarded old Butch the "No Bell Piece Prize," but they also awarded him the "Pulletsurprise" as well. Clearly old Butch was a politician in the making. Who else but a politician could figure out how to win two of the most coveted awards on our planet by being the best at sneaking up on the unsuspecting populace and screwing them when they weren't paying attention. Vote carefully in the next election, you can't always hear the bells.

      High Country Suburban build confirmation

      By 3CarSeatDad · Posted

      Can someone confirm if the GM order workbench terminal is able to validate a custom build sequence:   1) Initialize the Allocation Base: Open a new vehicle build queue, select the 2026 Chevrolet Suburban 4WD, and pick the High Country (3LZ Preferred Equipment Group).   2) Select the Diesel Powertrain: Go directly to the engine configuration screen and choose RPO code LZ0 (3.0L Duramax Turbo-Diesel). Ensure it maps to the MHS 10-speed automatic transmission.   3) Deploy the Seating Swap: Navigate to the Interior Options screen and enter RPO code ATT to replace the standard captain's chairs with the power-release 60/40 bench seat. Because you are not trying to force a separate luxury or air-suspension bundle, the standard, premium D07 Fixed Floor Console remains active. The system will accept this change immediately without triggering a warning message.   3)Apply Heavy-Duty Hauling Capability: Input RPO code NHT (Max Trailering Package). The commercial terminal will automatically bundle the required trailering hardware and software modules to support the diesel engine's maximum towing capacity.   5) Layer the Premium Tech and Glass: Separately add code C3U (Panoramic Power Sunroof) and code UKL (Super Cruise) to the order screen.   6) Run the Final Validation: Click the "Validate Order" button at the bottom of the interface.

      Looking at ordering a '26 WT because I want a std cab, std bed

      By revmanii · Posted

      Spent the last hour or 2 googling and reading up on the spacer thing. I don't like the loss of thread contact on the slip on spacers, but it appears you can get "extended" lug nuts that reach into the hole of the wheel to get back the lost threads. Looks like the only true hubcentric slip on spacers are at least .375". I'd want as little as I could get away with and don't want to cause other clearance issues going any thicker. Bora seems to offer what appears to be a well made .375" spacer and extended lug nuts. I searched here and did find a couple threads recommending Bora. But not cheap. By the time I buy spacers and lugs, new TPMS sensors, then pay a tire shop to install the new sensors, I suspect I'm going to be in over $400. Thinking about running out and getting some washers to put behind the wheel to see if .375" is enough to clear calipers, turn lock to lock without rubbing, and to see if the wheels/tires look strange pushed out a little. This would just be to check fitment.

      Road Master Active Suspension

      By Core-Lokt · Posted

      Roadmaster makes some quality parts; I have their sway bar. I considered the RAS, but I ended up bagging. I didn't know what kind of ride I'd get with RAS, and the bags have interior jounce bumpers, so I can run 0 pounds pressure. I figured I'd have the best of normal suspension ride with assist on-demand. But it seems you got pretty much the same in one item.
