I have a 2007 F-350 King Ranch. I have a rattle in the drivers side door. I have had body shops look at it and the said not to move anything. I have had the weatherstripping changed and still have it.
I've got a 2012 F-250 and have a rattling issue as well. It started on the left side and seemed to come from up behind my left shoulder. And, as soon as it stopped on the left it moved to the right. Again, when I have a passenger they report it seems to come from up behind their right shoulder. I guess the best way I can describe it is like tapping a wire hanger on metal. Any thoughts aside from from what 01yellerCobra replied above? Does the door have to be removed to check the rollers?
