Well, I pumped myself full of painkillers, gritted my teeth and ventured out onto the drive where I stripped the rear hubs and drive shafts. It was clear that they'd never been disturbed since leaving Tokyo nearly two decades ago. The cone washer were welded in their holes. Anyway, all came apart fine in the end. The locking washers (which are a bit of an odd affair) were actually slightly loose. They are locked in place with two screws into the locking plate and there didn't seem to be any wobble, but the pre-load was .4 lbs.Yes, half a pound. The grease had pretty much turned into soup, but the bearings were perfect. Same ones as the front - which I hadn't realised.
Anyway, cleaned out, re greased, reassembled and torqued up. That's another job off the list. If I can stand and walk tomorrow, I shall do the last swivel bearings and wiper seals. Then folks, I really am just abut at the end of the rebuild. Been for a spin and just cannot believe how smooth it is. Going like a bomb too.
I remembered the tip on locking the rear diff before pulling the shafts.
Is it time for a new truck do we think?
