Very recently, I came aware that my drivers side door was rubbing the body tub near the catch and taking the paint off. Investigation showed that the door had dropped at the rear end. Further investigation showed that the bottom hinge was extremely slack. So off came the door, and it was clear that the hinge pin had seized in the hinge hub and locked up. this now caused the small welds in the outer section to fail, resulting in the hinge pin turning in the thin sections of the hinge bracket and causing it to wear in a very short time, eventually this wear allowed the pin to disengage, allowing the door to drop and foul the body work. This train of thought continued, and it seems obvious that before the pin welds failed then when the door is opened, the seized up hinge pin exert a twisting moment on the door structure. This is a big long door, made of aluminium, and will quickly fail if subject to repetitive strain, and will lead to cracking in the weld joints at the inner end , which of course, is a feature of these doors. The thing to do, is to regularly grease the nipples on the hinges, or you could end up with a cracked door.

Re. doors, I too have a drooping problem the hinge design is not up to the job! anybody had a go to modify the setup to cope with stress of such a long lever effect. Wilst on this door subject I have tried to come up with ideas to create more shoulder room when at the wheel, to date nothing short of revamping the door and body to ressemble the classic style configuration would do. Has anybody dealt with this problem ?
