My thought is, with the 3 hinges and measuring the misalignment as you describe, you are assuming that the top hinge is off. Consider that if the center hinge, or lower hinge are wrong, that would make your measurement off. The screws holding the hinges should not be the problem, but I would loosen them and test fit the door for pin alignment. May be worth a try before the big hammer solution.
