I just spent about 20 minutes taking the diff out of the tranny. Now I'm not sure which piece I need to measure to see if machining is needed... I'm going to take the diff assy to a machine shop if machining is needed, but I want to know if it's even needed first.

Has anyone tried to R&R the roller bearing without the specialty tools? Or where can I find the puller and driver?

I also wanna clean those oil off of the diff assy before taking it anywhere, can I use Simple Green or will it damage the gear?
