He is rebuilding a locked '93 that was hit in the right front. Part of the damage was a bent axle, got a new housing, we extracted the birf and diff from the old housing, then assembled the new housing.
The diff had little/no bearing preload and a seeping pinion seal, so pushed apart. The bearings, gears, everything, looked very good.
Cleaned up the housing, before putting it together, took the opportunity to add some strength to the sway bar mounts. When lifted and flexed often, they are known to break, often taking out the brake line and ABS wires, $$$. It's a real pain to do when the axle is in the rig.
