My experience in decades of automobiles is that they never, ever go back on right or as tight as the factory assembled them. Every one I've seen has some corner that's always loose, something rattling, etc. I know you need the right tools too. I just am very leery of messing with door panels... to me, they are a one-time assembled, never touch them again thing, especially on a 14-year-old truck. Maybe I'm wrong.
