With the half shafts completed, I moved on to the differential. It was about what you’d expect a four decade old differential to look like.
So I cleaned the entire thing then removed one part at a time, refinishing each before I moved onto the next. The splines and gears still looked pretty good, so I’d clean and re-grease as I went.
Then I’d tape off other areas and give the aluminum a coat of flat clear then reinstall the parts I removed.
Considering how this looked when I began, I was very proud of how it turned out when I was done painting and reassembling.
Along with the other parts I’ve refurbished, this will end up getting a coat of automotive flat clear to fully protect it from the elements and scratching.
And with all the tar and dirt removed from this diff and all the other parts from the car (the underside especially) I probably saved as much, if not more weight than I’ve put back on in undercoating and sound deadening.
