I have a 1994 GT 5.0. Haven't driven it for awhile. pulled it out of the garage put air in the tires and took it for a rip. I noticed when coasting at 50mph the steering wheel vibrates. It only happens at 50mph. Any Ideas?
If it only happens when you apply the brakes, your brake rotors are warped. If it only happens at 50mph or higher, your wheels are out of balance. Could be that one of the weights on the tore got knocked off or something. They can't be too out of balance if it only happens at that speed, but it 's apparently enough.
