I worked on cleaning the rear axle. Sandblasted it, then primed it. and then dismantled it. Its a strange thing: the outer bearings, which should be covered in grease are virtually dry. At the same time the bearings and races look brand new. Someone as been in here as the locktabs on the large axle nut have been loosened then reset. The differential is covered with this suff that should be oil but looks much more chunky and black. But otherwise, it's in great shape. I cleaned it and reinstalled it. All seals are shot and I can't tap off the bearing to get to them. Off to the machinist.
