Ever since I put my truck back together last year with a new clutch, flywheel, and all the bearings, I get a bad shake while releasing the clutch to take off. It doesnt do it in granny, just 2nd and 3rd. It does it in 2nd most of the time, rarely it wont. Also discovered it does it in 3rd when my throttle stuck one day and I feathered the clutch out with higher rpms. I can see the drivetrain shaking through my shifter hole as well, but I dont know why it would be doing this. I used all name brand new parts. I think the clutch is a brute force if I remember correctly, and the flywheel is a billet steel model. Pilot bearing is new, bushing design. Throughout bearing is also new, came with the clutch. Rear main was damp when i changed everything, but didnt look bad enough to leak on the clutch and make it do this all the time. Any thoughts? Its really getting old and embarrassing.
