Hope someone can help. I just spent 2500 on a 3 inch bds lift for my ram 3500 Cummins. Lift looks great but caused a rear end vibration. In the rear I changed the shocks to fox 2.0s and added a 2 inch angled lift block that bds supplied. I have tried the factory tires and wheels that were smooth before the lift and the vibration is still there. I have read alot about drive line angles and how tapered blocks are bad but those are mostly with Chevy's. So I measured the drive line angles and cam up with 85 degrees downward angle on the transfer case and 82 degrees up on the pinion. My question is could that 3 degrees be the cause of my vibration and various speeds and upon takeoff. The truck has a one piece drive shaft with a single u joint on either end. Hope someone can help.
