    Hard to be of any assistance without more information.

    Is the bind a new thing? how is it binding up? Is it from a lift installation? have you changed anything that would now cause bind?

    does it have a posi in there? many came from factory with a posi in the rear, could be going?
    or maybe the question should be *did* it have a posi?

    Try jacking it up and turning the wheels by hand, feeling for resistance. Doesn't sound like brakes, but you could pull the drums off at the same time to check.

    I'd pull the cover, open diffs tend to eat through the pinion gear cup washers, and then bind up. Probably slowly grinding the gear teeth down.
