Question on rear diff.

Mine has a removable rear cover. It had a good bit of sludge in it. I don't know if diesel would have cut it or not?

I ended up scrapping it out by hand and using some solvent on rags to finish it up with.

It does have a cool triple diamond on the cover.



After getting it open. Still has the factory red primer on the inside of the case. Very heavy duty looking too.

Have a look in post one, but under diff mystery, a gent explained what that is to a tee, something to do with factory pinion setting, but don't move anything in side, diff,
