How do I remove the rear brake drums on a 1999 Dodge Ram Van 1500 ?

After removing the wheel and tire, remove the clip from one of the studs. Bang on the drum and try to pull it forward. If it won't move, remove the rubber plug from behind, and adjust your shoes inward, with a brake adj. tool, and then try pulling the drum off.
