Door made "klunking" noise and would no longer swing closed on its own.

With a screwdriver, remove the hinge cover-plate on the top of the door. This reveals the two nut-driven screws that hold th top hinge-plate: remove while children/wife/neighbor/butler/out-of-work-political consultant hold the door. Take out the screw on the Bearing plate and replace with new. (I replaced, but kept the old one. Like to replace parts that ride on each other in pairs, even if there is no noticable wear. Next, take the old Bearing-hinge from the bottom of the door that whomever is holding. Needle-Nose Pliers might be handy if your bearing-hinge is also shredded. Re-assemble being careful to place the bottom hinge into the Bearing without catching or scoring the Bearing hinge. Don't want to do this again in six monthes.
While I was under there with the base/bottom plate removed, I noticed the dust and crud and vaccumed after replacing the door.
