you have pretty much the same set up as me (at least from the t-case back, including suspension). what measures did you take as far as drive line angles-i.e.-shims, cut and re-weld perches, drop t-case, CV shaft etc. i have this killer vibration that i had almost figured out, then the next wave of mods came along and my rear is about 1.5 inches higher thn it was due to the weight reduction ( top and tailgate permanetly removed) now my angles are off again, and was just wondering what you had going. i really dont want to replace my 4 degree shim with a 6 degree shim or drop my t-case anymore than the factory spacers, but i am going to try both before going to a CV shaft. BTW-the shims are to shim the pinion DOWN. thanks rob AIRBORNE!!
