The hinges are NOT welded to the body. This is the same thing I thought until I actually started working on it. For the lower hinge....open the door and remove the two bolts from the door. (support the end of the door with a jack or something similiar) - also, mark the position of the hinge on the door and on the body with a marker or something. After the hinge is loose from the door, then you will be able to fit a socket w/ extension in between the front of the door and the fender. This allows you to remove the bolt from the outside. Then, remove the kick panel from the inside and dig around behind the wiring harnesses til you find a nut that corresponds the the hinge. Remove the nut from the stud and the hinge will come right off. The appearrance of a weld is actually just paint and some heavy gasket type of glue. The bottom hinge took me about an hour to fix. I've still got the top one to do, but haven't been able to reach the nut on the inside, so I keep putting it off. Any more help, just email me at prana_22@hotmail.com
