When I make a sharp left or right turn and accelerate there is a vibration that feels like is coming from reaend as if wheels are slipping or going over a washboard. Dealer didnt see a problem. Doesnt happen all the time but often.

if you have a limited slip differential, the clutches amy be slipping on turns. change the fluid and add an additive for posi rears. it is whale oil and stops the chattering.
