Have a 2004 with 134K on it. Door was making a strange squeeking noise the other day when I opened/closed it. First thought it needed some lube on the hinges and the part that restricts it opening too far, but had lubed it not that long ago.
Closed it and heard a loudish " popping" sound and looked at the part that restricts the opening and the whole thing had broken off inside the door. It was still bolted to a chunk of the door about 1" x 3" and the door had two longitudinal cracks, about 2" long, radiating out towards the outer part of the door at about the 2 and 4 o'clock posiitons!!!
Don't know if I can get to that part of the door after removing the inside panel, but maybe I can construct a "patch" and use some self tapping metal screws and epoxy to hold the patch or need to find another door.. Been a good truck (except for the new tranny at 78K) and plan on keeping it for a long time.
