BMW E21 Rear Differential Restoration

Hello YouTube-

We are working on another project with our E21 restoration. We decided to do a restoration on the rear 3.91 LSD differential. As you can see, it was in rusty shape and needed some help. First order of business was to try to scrap as much of the debris we could before hitting it with the pressure washer. The we could begin disassembly and really be able to clean each individual part up. After all of the grease and oil was removed, we took it over to our modified Harbor Freight blast cabinet (https://youtu.be/BiuGZusZYts) and removed the remaining rust and old paint. Next up was metal etch primer and the a few coats of black urethane paint.

Now we get to reassembly the entire unit using fresh o-rings, seals and gaskets. Doing our best to try to now scratch any of the nice new paintjob. As you can see the end result is an amazing transformation. Old rusty diff turned into a brand new looking unit.
