Rebuilt front diff with a TrueTrac, and some sort of solution for my rear springs.
I need to get some sort of front bumper on my 92...and get my winch fixed. Haha.
Bucknut, I would do shafts over a locker. If you lock the front end on stock shafts with your hp/tire combo...bye bye birfield.
I think your probably good on the knuckles until your in the 40" tire range. I would get the ARP studs though..
Really depends on your wheeling style and the terrain. I would at least truss the axle and knuckle balls if you havent already.
When you get that done,let me know how you like it.
