No on the pinion adjust. This is the first time I took it in, It does appear to be better but still vibrates. I am beginning to believe the suspension with the Ranchos is just too stiff and I feel every bump in the road. May have to try the Bilsteins like I had on my 08.

Fountain_NGA I have a 2015 Silverado CC My original tires-SRA- were replaced at 7000 miles due to sorry tires and vibration. Replaced with Michelin LTX2 and I still have the vibration. Road force tested and rebalanced and still have vibration !#!!$!$!! Tech says MINOR vibration. Asked him if he was paying for truck would he call it minor? He just looked at me............Trying to decide if I can live with it.
