Have you tried shimming the hinges?
Is it possible that you have a busted hinge? Open the door, and lift up on the open end of the door. If you can feel noticeable movement, you've got a busted hinge. This was a common problem on the 83-87 Chevy trucks. I realize yours is a Ford, but it's just a thought.
