What year is it?? Is it a 4 speed?? This could be several things from a wheel bearing, CV joint, or even a differential pin walking out and cutting into the case (Very common in the 604 transmissions) Give us some more info on the vehicle: Year, engine size and 3 or 4 speed would help greatly… transman
