While i searched this forum up and down, it seemed that everyone one said these hinges are not rebuildable. I found replacement door hinge pins and bushings from Rockauto and decided to go with it. This 15 or 20 dollar fix sure as hell beats what you guys have said in the past about buying the whole hinge from the dealership (costing above 75 dollar at least, then its not painted to your car)
dorman 38490 is the part number, also might be found at the "help" section of your autostores..
I took a jack and took the pressure off the hinge, unbolted all 4 bolts that you can see when you look in the jamb (not the ones bolted to the door or firewall)
(this was a 1 man operation btw and took less then 20 min)
Put the door on the table, made an X on the old riveted door pins. took a punch and popped them through. took a pair of pliers and removed what was left of the old bushing (practically nothing)
Simply put the replacements in the holes, tighten down the nuts, hang back up your door.
Theres no need to readjust any body lines or screw around with that. the 4 bolts you take out, all will align back to the old spots leaving no need for adjustments. . You can put some grease in the new bushings or squirt it later..
beats trying to shim and replace the whole hinge when thats not needed.
