Fighting the same thing. Tires have been road force balanced 4 times now. 1st dealership was a nightmare to get a loaner at so went to another one. The 1st time the did road force the numbers were in the 30's and they got them all down between 15-20 and I could still feel it. GM had them change tires to different wheels and got all the numbers under 20 but the vibration got worse somehow. Still waiting on the latest update.

Zach, what update are you referring to?

From GM to tell the dealer what to do next. Not an actual update for the truck.

I gotcha, there’s a thread for the HD trucks where they are having to reprogram the steering to get rid of a shaky steering wheel - wasn’t sure if something like that was going on with the 1500’s now too.

Ah. Not that I know of. They told me next steps are either new tires or replacing parts in the rear diff and driveshaft

From what I reading it seems to be a pinion angle issue.
