Thanks for the comments.
What is a bit perplexing is rollers on the other side of the same bearing looked to have very little wear. Possibly a chunk of stuff went through that bearing and then fell down in the sump. I don't know. I'm glad to hear the gov-lock will last - of course the rear end place was saying they go out about at 125k miles with disastrous results. I was reading about the gov-lock and it seems it will not lock above a certain speed (20-25mph), that's comforting to know. I don't rely on the locking feature - I think it came on one time since I've owned it. I was crawling over some rocks up in the Sierras after ignoring a don't-go-here-without-4WD sign. I finally got turned around and back out of there.
