Lookin' good Mike, certainly better than mine looks following a good cleaning and replacement of the oil-seals.
And that's been a long project for me, due to a diversion into chassis-repair.
I was in the process of removing the diff and learned the hard way to be careful with the torque-rods. Trying to remove the nyloc nut at the back end of one, I applied some healthy torque to the nut at the back end of the rod- and the whole rod rotated, tearing the chassis!
I dithered about it for a while, tried to find a person skilled in welding who would be willing to come to my house and crawl under the car, then eventually decided that I would just have to do it myself. I'd welded before but just barely.
So first I needed to acquire the welding equipment. I picked up a cheep flux-core machine, helmet and gloves. Then I got my hands on a bunch of scrap off-cuts of 16 & 18 gauge mild steel sheet to practise with, then found that my helmet was crap and I couldn't see what I was doing. Took a few weeks to get a better helmet, then more time figuring refining the use of the speed and voltage knobs, then once I felt OK about that, moved the practise-pieces to vertical since how the repair will be oriented.
Finally today I got the job done. Had to grind-out the head of the bolt that had been welded to the chassis at the factory (not really sure why they did it that way, especially after one of them broke sometime before I owned the car), then got the patch-piece welded on. I would describe my welding as 'ugly but strong,' and given a choice I'll take ugly over pretty. Ground-down some ugly beads and filled back in a few times and ground some more, but I think it's good and sturdy. Cleaned it up, shot some primer over the repair, should be good to go now. Will prob'ly re-fit the diff and start putting it everything back together next weekend.
