I am flushing the differential and noticed that the fluid actually looked really clean. However, the actual differential is almost entirely black. Is this something that should be cleaned? If so with what?
I know there are many people out there that are addiment about leaving older "worn in" areas alone and was not sure if this was one of them. I was thinking about spraying it clean with contact cleaner....thoughts?
