Jul 01, 2012A few days ago I began to feel and hear a vibration with grinding or rotating noise when cruising around 40 MPH. When I'm coasting, I'll give it some slight acceleration to maintain speed, and so I'm basically feathering the gas pedal. This is when I start to feel, in the gas pedal and floor, a rotating/grinding, and you can actually hear it

Last March (2010) I put new tires on my '05 WK, and immediately thereafter I began to feel a nasty vibration/grinding from the front wheels while making slow speed turns - either direction - only when the car was cold. After a mile or so or driving, it gradually went away.

Noise (vibration) when turning right. Grinding noise (vibration) ONLY when steering right. Noise is speed dependant (not RPM). Noise continues if shifted into neutral (with vehicle is coasting) Most noticible at 30-40 mph on smooth asphalt. Can be felt both in the steering wheel and gas pedal. Dealer could find nothing, said rotate the tires.
