Glad I decided to redo the axle seals and brakes. First of all, the gear oil was *black*, with a burnt smell. No metal shavings, but very close to causing issues. Second, I had leaks around both axle seals. And third, the brakes had ahout 25% of their useful life left.
Everything's done! New seals, gaskets, rotors, and pads. Plus, I got a geat deal on a differential cover, and I've got an extra quart of fluid capacity now.
Wish I'd taken more pictures, but you can see how bad things were before I started!
Edit: somehow some of my post got deleted? Anyway I added it back in.
