Man, what a pain in the butt. I don't know what the 4 Wheel shop was smoking but my angles are very different than what they reported. I'm reading 7 degree downward on the transfercase output and a 2 degree upward on the pinion.... they said 9 and 3, but that was BEFORE I flipped the 2.5 degree shims. So they were pretty off. I'm wondering if they had it on the lift when they measured.

Anyway, I'm thinking I should order 2 degree steel shims and put them in the correct way. That way I should have a 7 degree downward from the TC and a 6.5 degree upward pinion, right? Current pinion is 2 degrees, take out 2.5 degree shims raises is to 4.5, then add 2 more degrees gets me to 6.5. Short of just flipping the aluminum ones back around (where I know I had no vibrations for a few months), I think this is the way to go.

you can also do a T Case drop. That was my solution

Look it's a 4.6!
