I am still desperately trying to diagnose my driveline vibration. New differential and axle bearings. New u-joints. Driveshaft in phase. With clutch engaged it runs smooth for the most part. As I get to higher speeds I can feel a little vibration. About 50 MPH. As soon as I push the clutch in and disengage it I get a vibration. The more I slow down the worse it gets. It finally stops when I am under 10 MPH. If I reengage the clutch it stops.

I am a rookie when it comes to clutch and transmission so try not to laugh. Could the clutch be out of balance? When it is engaged it is stabilized but when disengaged it is free to wobble? I am just throwing stuff at the wall to see what sticks.
