The rack and pinion is not working on the power steering - Chevy wont cover because the truck has been lifted. The truck was lifted the day truck was purchased and it only has 5196 miles on it. Took it to 3 lift shops and all said nothing is wrong with the lift and their own lift person said the lift was done perfect.

Constant vibration/shake coming from the vehicle at any speed above 65 mph. The truck has been like this since the day it left the dealership. When on highway and vibration is felt, putting the truck in neutral does not change the vibration, slowing down makes it slightly worse, speeding it makes it slightly better. Feels like there is something seriously wrong with the geometry of the truck making it unsafe to drive at highway speeds. Road force balance was already done and the problem persists on a brand new truck.

Driving at highway speed holding the steering wheel straight the truck will move quickly to the left lane some time and then other times to the far outside of the right lane. Also I have had it move all the way to left lane and the all the way back across the right lane to off the road. Have notice as well that you can be turning the steering wheel to the right and the truck is still going to the left. When driving in a curve and coming back to center from the right it will snap back really fast not nice and easy like from the left. The truck has done this from day one I have tried to get GM to fix it but the say there nothing wrong I have drove 7 other truck like mine and they all had like there should the drive straight down the road.
