Man I cant see how ur 5 degree pointed up, it needs to be pointed a few degrees down.

My trans is at 0 degree and my rearend is at 3.5 degree down. The vibration is still there and it not bad at all. Just at 70mph and after that its gone.

I installed a belltech flip kit that uses shims which made the adj. alot better.

Wheelhop is still there and I dont get it why, I never had a problem with it

Get some pics of that reareand.
