At this point T5 out of car with bellhousing , pp, clutch on car and new motor mounts, still vibrates. Used old flywheel, bh, pp, clutch during orginal install. Getting ready to remove bh, pp, clutch and see if still vibrates. If vibrates, will remove flywheel and test again, if still vibrates, may have to replace crankshaft bearings? Have already replaced harmonic balancer, water pump, alternator.
