Sounds like the right rear drum is locked up. Jack it up and remove the wheel. Block the front wheels. Have someone set and release the parking brake as you try and turn the wheel and see if the cable running into the backing plate is moving inside the housing. If not, you'll need a brake adjuster to loosen the star wheel. If you can hear the brake shoes moving inside the drum, you have a roasted bearing. Not hard to replace.

Oh, if it's the bearing/hub, you should be able to get one from a pick and pull junkyard for a few bucks. If the brake cable is rusted with the parking brake engaged, it shouldn't cost much more than a couple hours of work getting it free and a can of WD-40.
