hi john, in 2015, i did 3, yes three, AMC doors, so my memory is still fresh. 2 on an Eagle, one on a Hornet. Ok, here's what you do:
Tools; 1 regular 1/2" wrench, One 1/4" drive ratchet with a 1/2' socket., a 5/16" and a 3/8" nut driver/or socket. One T47 torx socket. AND, VERY important, one helper, next to impossible to do by yourself. Also, a good punch set .
First, take off the door, this is the easy part, all you need to do, is, using a regular 1/2' wrench, is take out the six bolts, 3 upper, three lower on the door. Of course you know to disconnect any speaker wires, etc. remove door, set aside.
Now you have access to the hinge bolts on the body, a bit of a pain, but accessible with a 1/4" ratchet.. Now you also want to remove the fender liner. Don't really have to take the wheel off, ( I didn't), but may be easier for you. You can reach in from the wheel well, (a droplight helps!) and remove bolts Again, three upper, three lower.
OK, door is off, you have both hinges in your hand, right? Wash, degrease, repaint now.Now, to rebuild the hinges, hey, this is still the easy part! There are a couple of ways to do this, you can order AMC repop hinge pins/bushings these days, and go stock. I started doing this before these were available, so this is how I do mine.
Get NAPA #675-5142 pin bushing kit. need two, about $5. each.,$10./door, this is a GM/universal pin/bushing.. OK, put your hinge in a vise, and knock out the pin, should be easy, since they are worn out. There will probably be bits of brass bushing left, and will fall out. Your hinge is now in two pieces, right? OK, Inspect the holes where the bushings were. Are they mostly ok? If so, GENTLY tap the new bushing in. The NAPA bushing is the EXACT size of the AMC hole. Remember to orient the lip correctly. Ok, now for the pin. The pin is NOT the same size, a couple of thousands larger. Don't panic, it's ALL good. put the pin half of the hinge in a vise, and drill out with a "R" drill. You are only going a couple thousands over, so being PERFECTLY straight is not that big a deal, but try to drill as straight as you can, both holes, top and bottom. OK, now you have two more or less brand new hinge pieces. Put them together in the appropriate orientation, and GENTLY tap the new pin through. It can point up or down, doesn't really matter. If you get confused about orientation, check your passenger door, the hinges are EXACTLY the same, just upside down. In other words ALL Hinges are the same, just mounted differently. Do the same for the other hinge. You will notice one has the midstop and one doesn't, all good. Remember which went on top, and which on bottom Midstop goes on bottom.
OK, now you have two brand new/rebuilt/cleaned/painted door hinges in your hand. Whew, believe me, that was the easy part.
OK, now to rehang the door, you WILL need a helper, those doors are real steel and HEAVY! Ok, bolt hinge loosely to frame, meaning from inside the fenderwell, have helper hold door, and bolt door to hinge. do not tighten. DOOR will be WAY out of alignment. OK, now this is the hard part, getting the sucker back in line. Basically this is where my instruction ends. from now on it's trial and error, unless you're an experienced body man. you tighten a couple of bolts see how the door closes, too low, you loosen and lift, tighten again, etc, etc. You may do this 20/30 times, it's a skill, but don't give up, the answer is out there! Last but not least, you can adjust the striker bolt, T47. good luck, gz
