Hello,
I recently took both my rear brake drums off to inspect the parts. I
noticed that the brake parts under one of the drums were filled with
grease. My question is where did the grease come from? axle? Did i
bust a bearing or seal of some sort? What parts do i need to replace?
thanks!

Hi Don,
You should have the AMC 20 rear end, with inner and outer seals:
http://www.billhughes.com/temp/amc20axle.pdf I would just the replace
the inner seal and repack the wheel bearing with grease, the outer seal
is mostly just a dust cover, and replacing it will ruin your hub, axle
strength. But if you're gluten for punishment, mark the hub and axle as:

free with a deposit from the store you bought the seal:

Is it grease or is it dirty oil?
If it is gear oil full of dirt, then I would suspect the seals, if it is
actually grease, then I would be worried about a bearing that had
overheated melting out all it's grease. If it was the bearing, you
should see some play in the axle with the weight off I would think.
When mine leaked gear oil, it would actually run down the inside of the
tire. If you park on a slope and oil pours out, you have found a bad
seal.
