I have a 2007 Silverado 4WD 4DR Longbed. I am getting a vibration between 55 and 80. The driveshaft and rearend and axle bearings have been checked uot at the local Chevy dealer.They installed a new carrier bearing and changed the rearend fluid. they said it was fixed but it isn't. I'm tired of throwing money at it for nothing. Does anyone have any suggestions?It has 61,000 miles on it.

 

Have you checked your tires? Bad tires can cause a vibration at highway speeds.

 

Yeah I'm gonna put a new set on this weekend. It really don't seem like a tire prob though. It's more like a bad bearing , the vibration is more harmonic. Gonna see what the tires do not ruling them out just yet.
