And GM will keep saying its the tires

Thats right. I had two balances and aftermarket wheels/tires and same deal. Im surprised it only vibrates 40-45mph and 70-75mph. I just emailed GMC the video to see what they say. Unfortunately my warranty has passed and doubt this is covered under power train warranty.

Here's part 2. Its all the drivers side as the passenger side isnt bad. I slowed it down and took a couple angles/measurements people PM'd me about. I had to put it all back together until I get new axles then I'll swap them out and make a video if needed. Until then I'll keep enjoying my $40k massage.

 

 

That is horrible runout, you are positive you did not hit something correct? What was your tire wear like on that tire?

Wow. Can't believe how bad that is. But according to GM it's within spec.

So where is that "Slop" coming from is the question? That is why I questioned "MR I solved the riddle of the century" removing 18 grams off the area in question does nothing...........Let's slide those Yukons on in Mate!

I haven't hit anything. Passenger side is the same way but not as severe. Wear appeared normal but then again tires only have around 2k on them. I rarely go over 40-50mi round trip in the last 2 years.

They need to source better parts then. I'm tired of spending time and money trying to fix my truck that only has 22K miles.

As long as people keep buying them they have no reason to spend additional money on better parts. So you have 2 options, keep spending money to fix it yourself or don't. It's up to you. I've seen a little bit of everything in this thread but one thing I have NOT seen is someone who opted out who wishes they hadn't. None of us wanted to move to another brand but we are all really happy we did.

New guy here and first post. Found this place while doing a search about the vibration I'm getting in my 2016 Sierra that I've had for a month now. Started at around 400 miles and now I'm at 2300 miles. I really feel it in my steering wheel and it's almost constantly while vehicle is moving. Going in tomorrow morning to dealership. Didn't read this entire thread but quite a bit. Has anyone measured their wheelbase driver side compared to the passenger? Mine is 3/8th of an inch longer on passenger side. This is a new one to me. Sorry if this has been discussed but searching has not given me anything. I'm coming out of a 12 year stretch with an 05 Ram 2500 4x4 with a Cummins. That truck was loud but I never had an issue like this. Love everything about the Sierra except for the vibration which actually makes my hand numb after 30 miles or so

Same problem when I bought mine 7 months ago. They put shims on the motor mounts and the steering wheel vibration went away. There should be a TSB for this. I'll edit my post when I find it.

TSB Reference#PIP5211B

Holy crap! The amount of "wobble" created at the tire from the face runout is shocking. No wonder there is some much vibration/shake felt in the cab. Still doesn't explain why this issue seems to come and go for some people but regardless, that is seriously defective.

 

OK, has anyone gone into their dealer with and shown them the amount of runout measured on their axle flanges? In all the posts on this thread, I don't recall anyone saying that the dealer ever checked these measurements or any GM TSB focusing on the axle flanges. Obviously, that the first thing to check. Heck, I'm definitely going to check them on my Yukon first chance I get.

 

Just a side note, not sure if the lateral runout on the face of the protruding "hub" means much,maps that surface doesn't really engage anything. BUT, it is indicative of any overall poorly machine part, as everything seems to have a ton of runout.

 

Bottom line....those axles are JUNK!

I believe the root cause of all our shakes and vibrations are mostly contributed to poor tolerance stacking. No one probably did a good job at Advanced GD&T on a completed assembly or component parts - ( Geometric dimensioning and tolerancing, often referred to as GD&T, is a symbolic language used on engineering drawings and models to define the allowable deviation of feature geometry). All these problems are causing our trucks to resonate (vibrating) at a frequency and amplitude that varies based upon changing / variable conditions. Under the right circumstances, multiple components begin resonating sending harmonics (vibration waves) until we begin experiencing unacceptable conditions. I understand we have stiff frames with high durometer frame to body bushings that aren't helping absorb these vibrations. Some of us have stopped enough of these resonating components to deem the vehicle repaired. Believe me there is still and always will be resonating vibrations, but only at an acceptable level. My truck has been deemed acceptable (smooth) for over 1,000 miles, but it took me replacing the rear ring gear to achieve this level. Others may find changing axles, truing drive shafts, balancing tires, & ect to get their truck to an acceptable level. My point is to identify some of these components by removing them from the equation and you to may get your truck to an acceptable level.

Axles will be installed next weekend. At that point on the only thing after the transmission that is OE will be the axle housing and calipers. I've replaced the drive shaft, ring and pinion, carrier, rotors, wheels and tires.

 

I will be taking run-out measurements on the factory axles.

Zmnypit, could you see that much wobbling when the wheels were on the ground or was it only noticeable once the truck was on stands?

Its not as noticeable on the ground but now that I know its there I catch myself looking in the mirror as I'm driving and you can see the wobble. It looks like a bad tire when driving.

Did you check yours before ordering new ones?

    • 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.
    • Better than stock but that's like putting lipstick on a pig
    • 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, 
    • 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.
