sounds to me like you have a mess on your hands, are you sure you got the pinion angle adjust right when you installed the flip-kit, front drop, and gears. If you changed the rear height, set the angle, and then lowered the front afterwards, you may have screwed up the pinion angle again. Honestly i'm just working from what i've read and seen, Haven't actually done this myself. just so ya know where i'm coming from

I set the pinion angle at ride height. I installed all of the supension and rear end parts at the same time.
