My '16 Denali has 6660 miles on it. Still vibrating after several sets of tires. I'm also in the 70-80 MPH camp.

 

When it was in last week for another attempt to fix the vibes, they gave me a '16 Crew Cab Regular Box 4x4. Had that running at all sorts of highway speeds and rode like a luxury car. Wheelbase have anything to do with it maybe?

 

Anyone with a 6.5' bed Crew having the vibes?

Wheel base has no bearing on the shake. I have a RCSB and it shook awfully, but had the driveshaft trued and runs smooth as glass now!

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 was getting frustrated with my truck approximately 7,000 miles on it. The dealer originally road force balance the lousy Goodyear ls2 tires reducing the vibration to an acceptable level. But those tires are horrible.

I upgraded at 700 miles to Goodyear Wrangler AT much better traction and braking. The Goodyear store didn't have road force balancing though and after the first rotation and rebalance the vibration just got unacceptable.

 

Was really thinking about checking out the drive shaft. Then I just decided to have the tires road forced balanced. The shop had to remove all the existing weights and start over. One tire is out of spec at approximately 32 pounds the others were in the 20 lb area. The results were a very significant improvement or reduction in vibration.

 

My guess the vibration will come back in the next 1000 miles. If it does I will be seeking out a shop that will sell me a set of Michelins and road force balance them to 15lbs or less per the GM spec.

Did it feel like a shaft wobble (i.e. bad u-joint) vs tire? They feel considerably different usually. Mine definitely feels like it's tire frequency, but it could be a harmonics issue I suppose.

Well bad news boys and girls. Just went and had the oil changed (free) on my truck... Yes even though my trade assist is going through at the end of this week, or sometime next week. I was talking to the shop foreman and he confirmed that the shake is NOT fixed on the 2017's. He advised to only get 18" wheels, he says the 16, 17, 20 and 22 inch wheels are the worst. He also said to stay away from the Denali, which I find odd, because of all of the trucks I test drove, the Denali's rode the best, with the least amount of shake. He has had a bunch more in for the shake, and said that its hard and frustrating to have to try to explain to a customer why their XX thousand dollar truck shakes and they can't fix it.

 

Now I'm seriously scared about my new one.

There's a shocker, What's the old saying about insanity? Doing the same thing over and over and expecting different results. Very fitting for this situation, just keep on balancing, vector matching and replacing tires until the new platform get's released. I actually feel bad for the service departments left twisting in the wind to field all the pissed off customer complaints. To exacerbate the issue GM won't even pay for the work they do under warranty after a few attempts. "Vibrating as designed but within specs." At least pharmaceutical companies tell you the product you are buying is going to make you sick and $h!t yourself. GM really needs to mention this fact in their commercials and brochures. Possible side effects of buying our trucks or SUVs include motion sickness, headaches, vertigo and a feeling like someone just jammed a broomstick somewhere very unpleasant.

Nausea at the amount they cost for all these issues would be applicable too

Unfortunately yes

@jesse D- any tips to get dealer to buyback? Mine is still in shop for first visit. (11 days and counting)

I'd be cool with a few grand trade assist as long as they don't make me get another truck!

 

 

I really want to just get a sedan at this point...

I feel that, I'm so disappointed I kinda wish I had gotten the Audi I was looking at. But I like trucks more

Mine vibrated at 26 miles, driving it off the lot on delivery. I got the "it's the tires" excuse and was told to drive it a bit to see if it got better. Wish I'd known.

 

See if they'll put your current tires on the Denali you want, and drive it. If your current set is supposedly RF balanced correctly, the new truck shouldn't shake. If it does, ask to try a different one.

has anyone tried anything like this? I'm sure it wont help with the vibration, but I'm just wondering.

 

EDIT:

 

according to this it might do something

 

Wow, that REALLY sux JesseD. Sorry to hear it.

 

Thru various sources I have read/learned a little about the Denali magnetic suspension. I can understand why/how the mag suspension would better isolate the passenger compartment and reduce the vibration felt in the cab. But it seems that, all the mag suspension is actually doing, is doing a better job at masking the the vibration than the conventional suspension does. The vibration is still there and most likely caused by a rotating part, or parts, of the drive train. And or maybe a frame or aerodynamic issue... or all of the above?

 

Regardless, I'm confident the GM engineers know what the problem is. Too bad GM won't be honest and fill us in on what the issue is. Hope and pray for a whistle blower. Where the hell is Wikileaks when ya need them!?!?

 

So, what's your game plan? Can you hold off on your deal with GM until the 2018's come out?

I was originally looking at the Colorados and Canyons when I bought my vibrating Silverado. Wish I got one of those instead. I looked thru the mid size truck threads here on the site and vibration seems to be an almost non issue with the mid sizers. Canyon would be the bomb with a 5.3 LOL

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
