Chevrolet Repair: 99 chevy suburban drivers door, chevy suburban, bushings

Question
the drivers side door rattles, is the striker pin worn or is it the bushings on the hinge?

Answer
Jesus,

 The spot welds break loose on the rear window track and rattle when going over bumps.  See if it rattles with the window down or changes.  door panel will have to come off.
 There is an updated pin and bushing kit for these trucks.  You will have to have a body shop put them on though.  they can be difficult to adjust.
