On my 99 F250 crew cab the right rear door rattles only in winter. As setup from the factory the door was hard to open, but did not rattle. I had the dealer adjust the door to be easier to open and the rattle started. What should I adjust? I have asked dealers to fix this but unless they are working on a new truck and a repair with flat rate hours they say can't find your problem!

 

Take a look at this Thread, it has a great door seal mod video.
