I just put in new bushings and springs. The nylon bushings did not look too bad, which I found odd. But the springs on both sides were sagging. One side of each spring on each side sagged 1/8" and 1/4" strong on the worst side; when compared to the new springs. They looked like a banana shape. I picked up a couple degrees positive camber off new springs and bushings.
I would put the money towards first: selectable locker, upgraded axles, with 35 spline outers, yukon locking hubs. Unless your racing and doing the whole enchilada.
Oh and PICS! We need PICS!
Another two cents.... worth the price paid!
