limited slip diff.

Unless you know the history of the car (or looked) you really don't know what's back there. Has it worked before ???

hello people: I'm the second owner and I've owned it for years but a noisy diff. is the only clue if there's a problem. Any other clues if it's junk? How about a replacement? any experiences?

I would do a little more research on what you have like pull the cover and what size differential you have then come back and ask questions

You change the fluid you should know what you have. You have owned it this long why worry because both wheels didn't spin in the snow?
