I'm sure someone will just jump in and say just use elbow grease or remove the strap and lift up..... Please don't. When I first got my hands on the jeep 2 years ago it still had all 4 nuts on, and i snapped off a portion of the hinge in the upper driver removing the nut. I have doors that have never been removed in 16 years. I got the passenger side door off using a jack and piece of wood easily. It was seized but the hinge pins were in good shape and moving freely. I began to drive out the old bushings and I am reusing the hinge pins.
On my driver side both bushings and pins need to be replaced. My upper driver hinge is showing a decent gap of maybe half an inch when jacking, it is ready to come out. My lower driver hinge pin is seized and doesn't move with the door. I jacked up with a wooden block as close to the hinge as possible and have been moving the doors. I sprayed kroil for 10 days. The hinge pin makes alot of noise but doesn't move out any further. I put a towel on the top of the wood on the jack and scrapped some paint off the bottom of the door, took a long time to scrap the paint but eventually it happened. It's very minor and is nothing in comparison to the rust on the bottom of the door. Basically at this point I am giving about 3-4 full rotation cranks of the jack before it reaches resistance on the hinge pin. I also tried spreading the load with another wooden piece and hitting that piece with a rubber mallet. What option should I take next:
1. Use an air chisel on the hinge pin.
2. Use a jack that can reach the hinge pin directly. Maybe a bottle jack but the floor jack won't reach it.
3. Crank even more with the jack
