Why would you shim it down? Your tcase doesnt point up does it?
Front driveshaft vibes when tc drop is removed

Maybe you're right, i'm trying to picture it in my head without the Jeep here. Mark is picking up some 3* shims at Rusty's today. I probably only need a 2*, but they don't sell it in steel.

You have a LP 30 too. That would make it more prone to front vibes with re pinion being lower I'd think.
I shimmer my rear axle when I had a TC drop. Actually I had a 2 degree shim and 3/4" shackle to help with vibes. After I did that the vibes got significantly less. Now with the SYE I have just the 3/4" shackle and get random vibes but that's cuz I need another degree or two to point the pinion at the TC.

If you have a TC drop you are changing the angle of the rear output at the Tcase, you then need to match that angle at the pinion on your diff. It's the same principle as the above sketch for the rear I just don't think people are getting it. The angle of the driveshaft at both Ujoints should be the same. When you convert to an SYE you use a CV driveshaft in the rear and the pinion needs to be pointing at the rear of the tcase. Same for the front since it's already a CV.
So yes to shimming to achieve proper angles. I hope I didn't just confuse the situation more!:spin1:
