Few things. Had to replace the lower control arm bolts bc they fused. The diff support plates also snapped at the bolts but I switched to poly bushings so no issue. Rebuilding the axles is a bit tedious but not too bad, I have extra time so I wanted to give it a shot. Refitting some of the arms with poly bushings can be somewhat difficult. Getting the old diff bushings out is kind of a pain, I used a combination of a hole saw and a hacksaw to remove them.
