I'm hoping someone can shed light on this problem I'm having. I've developed a vibration in the drivetrain during acceleration . It's rather severe, not a knock but an occillation that transfers into the body. It seems to come from the front. As soon as I let off the gas it disappears completely. I have noticed that it gets worse during a right turn and almost completely disappears in a left turn. The frequency seems related to road speed rather than RPM. Dealer has replaced right front drive axle, tie rods and bushings to no avail. Car does not seem to vibrate at all when cold. Car has 103,000 miles on it. Any ideas would be appreciated as dealer seems to only be changing parts in a process of elimination.
