Shake or Vibration Issues

[mjj]

I went from factory 20's to aftermarket 20's am i pissing into the wind if I bring my truck in for the vibration issue?

I have larger LT AT tires and they told me GM engineer would not look at it with the non stock size tires. My dealer actually swapped my tires back to stock size from another truck on the lot while they tested mine. In the end they blamed my tires. So yeah depending on your service department they may give you some crap about em.

I'd like to think that my tires are just not being balanced properly by the touch holes at the dealer. I am half tempted to take it to a good tire shop, let them have it for the day, see if they can fix it, and send the dealer I bought it from the bill for it.

 

Find an expert shop that can do a true road force balance. Call around and find out who is the best and which tech. There is a guy. The dealer won't pay for it either.

 

The first two weeks I took my truck to my brother which was an assistant manager at a tire shop. I watched him dismount and rebalance the tires. At slower speeds it was much smoother but at 70mph + vibration was still there. At that time I did not know what a road force balance was.

 

Then you can rule out wheels and tires.

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?

Well got my truck back on Tuesday and pinion and ring gear were replaced along with the the tires being road forced balanced. The vibration at 40 to 55 is gone and now vibrates at 65 and up. Taking it back on Monday to redo the tires, hopefully this will fix it.

I called my sales guy today, I'm headed out of state for work Sunday, so I couldn't do anything until Wednesday or Thursday, but he said they'd exchange my truck for me if I wasn't happy... I've only put 300 miles on it, so they should exchange it. They also said they'd take the 22's off and try 18's to rule out the tires if I wanted to.. The dealer seems to be willing to work with me to make me happy and I guess I'm thankful for that. I like the wheels and tires I have though, so I'll give them one more shot to fix the one I have before I go for an exchange... I'll keep you guys updated after I see them this Wednesday about the issue.

So far I've dealt with the vibration issue on my 15 Silverado for about 5000 miles. After the first visit about tre issue, its been a pain to get it looked at anymore. I kept pressing the issue and now after two tires being replaced, the vibration seems to be gone. I have a 400 mile weekly comute for work on the interstate. This week I felt nothing, no more console shaking, seat shaking, steering wheel vibration, etc. Keeping my fingers crossed that it's fixed!

I've dealt with the vibrations for 8500 miles now, they started at about 2k. Had the factory 20" wheels and tires road forced 4 times at 3 different shops, bought aftermarket wheels and tires went through 2 sets of rims first were raceline 18's, now on fuel 18's, 8 different toyo AT II tires to get the road force below 10 lbs on all 4 tires, still vibrates. New front struts and new rear shocks, sulastic shackles on the rear, retorqued leaf spring ubolts, resettled body mounts. Removed the front cv shafts, removed the front sway bar, rebalanced drive shaft, rephased the drive shaft 180 degrees to check runout on the pinion flange. Shimmed the rear pinion up 2 degrees, then shimmed the pinion down 2 degrees. Tried my buddys factory 17 inch wheels off his GMC. Disconnected the power steering to eliminate smooth road shake. 4,000 dollars later I still have the same vibration at the same speeds that the dealer acknowledges is there but is within GM's spec so there's nothing they can do. F*^!< GM. Couldn't eliminate the vibration. Now I'll try to figure out how to damp them or isolate them from the cab, really I just want to eliminate them from the steering wheel, the seat and console aren't too bad.

I hate to say it but I agree. Don't give up but after they rebuilt my diff. the vibration went away. They did replace all 4 tires and new shocks so it is hard to say which one was the culprit for certain.

Go an drive some other trucks they have. Make sure you take that thing up to 85 and run it for say 50 miles at varing speeds. Wish I would have caught my issue sooner to do this.

Hi Guys just checking back in. My 2014 GMC Sierra CC SLT 4x4 Z71 with 20's (Michelins) now has a bit over 46k on it. The vibration is minor in mine and tolerable (to me) after i put the michelins on it but I was wondering about the fact that I have a split in the edge of the drivers side running board at the second support back. Obviously the running board takes a lot of twisting force to do this which could be an indication that it is holding the crew cab body to rigidly in place? How many of the shaker trucks have the flat running boards on them? I am thinking about taking mine off now just to test my theory but my shake is pretty minor and I am not sure if it is worth the effort. Have any of you guys that have major shaking and done basically everything else thought about trying this? Take a close look at the bottom outside edge of your flat running boards right at the supports you will probably see the hairline cracks just like I am seeing in mine? One is split badly and visible when you walk up to the truck. If I knew that they had fixed all these issues on the 2016's I would go trade I guess. Love the truck

I went on about a 2.5 hour road trip last night. The first half it actually rode great and was quite surprised. I had my girlfriend and one of her friends with me and they both said they didn't feel much other than road. I went through and toll plaza and got on it pretty hard coming out of it to get around a semi and it wasn't quite as smooth the rest of the trip, had a slight vibe. Wondering if my tires slipped on the rims some. Wishing I would have marked them before the trip.

it baffles me that the wheels on these trucks could be slipping inside of the tires... wtf?

[Tattooo]

I know....weird

[longhorn_cop]

I think someone wondered if older GMCs vibrated. I had a '13 GMC CC, before this vibrating '15. The '13 never vibed and rode like a dream.

I had a a 2000 yukon & 04 sierra that never vibed either
