I am curious if anyone has had the infamous 'vibration issues' at highway speed prior to lowering and if lowering helped the condition at all?
I have a 2016 Denali XL w 22 CK158's (6 spoke GM) and have been fighting the vibration issues since the 6K mile mark...23k now...I make the dealer RFB the wheels/tires at every oil change and the vibration is better for about 1k miles then comes back. Dealer replaced two tires on the second service after I complained it was still vibrating....but to this day it still vibrates above 70mph - maginute of the vibration depends on the road and load (# of passengers)...but annoying as hell! Dealer says "it's within acceptable limits"...which I call BS! If it wouldn't take forever and a significant amount of my time fighting the dealership/GM I'd get a lemon law lawyer to press the issue w GM to buy it back!
Anyway main question....would lowering it lessen the vibration issues? Or has anyone experienced a change after lowering? I've heard one 'fix' to the vibration issue was to change the differentials ring/pinion (pinion pre-set torque is likely out of spec leading to the driveline vibration)...wondering if the slight pinion angle change from lowering would affect the vibration....? I really want to lower this thing but not if it's going to make the vibration worse...may wait another few months and trade it off for another Suburban/Yukon...
