Looking at the oil is not a good way to tell. My transmission and rear end both had me convinced they were shot and the oil analysis on both of them came back with flying colors. I would be more inclined to take a powerful magnet through the oil for a while and see if it comes up with anything on it. If it does, then that's different. But for general maintenance I've become a firm believer in Blackstone labs.

I don't know what the stuff is, but BMW and GM used it, my guess is a additive that helps cut down wear or helps resist wear under pressure.
I paniced also and nearly bought a new differential getting prepared for the fix when the oil sample test came back perfect I was in shock.
That was about 25,000 miles ago and it still runs quiet and happy on the oil I installed so I think the Oil Test was accurate.
