Possible leak?

[Josef86]

I recently replaced the parking brake drums on the Ex. The passanger side rear was bone dry. On the drivers side rear it looked like something may have leaked out at one time.

What could be leaking? Axel, differential? How much work would it be to replace a possible bad seal (or money if I needed to take it in).

I am starting to think if there was a leak it was the axel seal. About how hard is it to change one?

Did you check the fluid level in the differential, and the master cylinder?

Good point, I know I checked one of those but not both. get back to you on that.
