alleggerita SG There's another reason for it..my uncle had it before on his Volvo S40 2.4i..Volvo's reason for that is wrong pressure for the hydraulics that works the power steering..if your's is a hydraulically-powered steering, this may be one of the problems..
Praetorian111 SG Have you do balancing yet?? At what speed do you steering wheel vibrate? and the age of your car.
