I have a 98 XJ 4.0 auto with ~5" of lift. I had a 1" t-case drop and 6* shims, things ran pretty smooth. I put in a H&T SYE with front DS at the beginning of the summer, took out the shims and t-case drop. Had to shorten the front drivehaft, a front XJ shaft wont fit mine for whatever reason. Thats a different mystery.
I can't remember what my angles measured out to, but a 4* shim should have put my diff right ~ 2* below the case output according to the writeups Ive read. I put the 4* shim in, vibes like crazy. Took it out, much better but still vibes up around 50. Thought maybe I should have divided the measurement by 2, since the pinion going up means the t-case angle going down too. Tried a 2.5* shim, just as bad as the 4* shim.
Ive taken all the shims out, and tried 2 washers under the x-member, it's slightly better than nothing at all, but not much still vibes around 55 and up. Its more of a noise than a vibration.
Any thoughts on how to get the perfect driveline angle? This is the only thing that keeps my jeep from going down the road as smooth as stock, giving it one more try before I find a driveline shop.
Thanks
