Driveline vibration problem

[Ironangel]

The desired pinion angle is 3 degrees down. I think the fact that you went to a single piece drive line compounded with a loose incorrect carrier backlash led to the vibration more than just pinion angle. I've dropped several coil rear trucks and never changed pinion angle on any of them and never had a vibration problem. I keep the two piece driveshaft's intact because they maintain stability under load and at high speed. Camaro's and Mustangs have two piece driveshaft's for a reason..."Just Sayin" ~Ghostrider~ PS. Glad you took the time to come back and clarify the problem Snipe, Kudo's...
