I've got a strong vibration around 3-4000 on the shifter. It doesn't matter if the car is moving or not.I'm going to get the driveshaft balanced anyway but what about this harmonic balancer? Where is it and how much is one to replace. Is there any way to narrow down the vibration? It doesn't make any difference if clutch is in or out. Help! Thanks. 91,5.0L
