I was rotating the tires on my '65 c10 and when I took the drum off of the right rear, I noticed this black stuff all over the brake shoes:

So, if it is the wheel cylinder leaking, I have parts for that...
If it is a rear axle seal... how does that work? I read about it in the shop manual, but I'm fuzzy on what to do inside the differential cover and what tools to use to properly make the axle come out.

Any tips or suggestions welcome.
