I just took it for an oil change. This is how it looks without the cover, the gears don't look terribly wrong I think, the magnet on the cover did have a lot of crap all over it though. We used 90 gear oil and I couldn't get a hold of a limited slip additive so I used just some regular "anti friction" additive until I get the good stuff. I just drove it for a couple of miles and it is a lot more quiet, I can still hear it but it's not loud at all and it doesn't sound all the time, just under light acceleration when cruising. I'm not sure what to do next haha. We have a long weekend coming up so I can't pull the rear end until next week. I guess I'll drive it like that for a while.
