I've been running them for a year with zero issues. So far so good. Front with spicer 5-760x u-joints, timken bearings, full cirlce clips, 35's and locked. Rear with timken bearings 35's and locked. Dana 44's.
My only complaint is I had to grind down the rear grade 8 bolts (wheel lugs) to clear my parking brake. Took the head half way down and so far they're good.
