FAQ
Worn U-joints, a bent or unbalanced driveshaft, a worn center support bearing, wrong driveline angles and worn differential parts are common causes. Vibration that changes with speed usually points to the driveline.
A clunk often means excess play in U-joints, slip yokes, differential gears or mounts. Left alone, the play gets worse and can lead to a failure on the road.
