Turned out to be very easy, especially since the oil somehow didn't make it to the brakes after all - just seeped between the hub and drum. Got everything cleaned up quite nicely and replaced the seal. Took about two hours with simple tools and lots of paper towels. I don't have a vent hose on the diff, just a small dirt-encrusted vent cap, which I wire-brushed clean and hopefully it works. I am able to wiggle the cap on it a bit.
