I have a 2006 ST and am experiencing a couple of odd things.
First of all there's a high pitched whine when above 50mph and get louder on right turns. There is vibration though the steering aswell as the floor. I wondering of the tracking and balancing might be off slighty as the car had been lowered before I bought it.
Second thing when my foot comes off the gas pedal, there's a clicking noise coming the either the dash or the engine bay.
Got any ideas?
