You can get some noise and vibration when the pilot bushing in the end of the crank is tight, loose or trying to seize. I think most people have gone to a roller bearing type rather than the bronze originally supplied by GTD. If your car is pre 1991 manufacture it probably has the 3:89 ring and pinion rather than the better cruising 3:44 gear set.
