I recently bought this rear from a junk yard. when I opened the diff. cover I noticed that the gears were filled with a wettish rust.(looks like they lost the plug and left it outside) rain most likely got inside the hole how do I fix this problem?

 

agh..

bad sign... you may be able to use them if there's only surface rust, pitting is very bad..

it is only surface rust. I can wipe it off with my finger

 

Get some diff fluid (80-90) and flush all the gears and stuff off. If it just wipes off, they should be OK.
