The rattle that has been given a good DIY fix on this site - the one where you open up the trim on the top of the door and put some foam etc in there - is that rattle the loud rattle I hear above the passenger door when I go over rough road?

The fix looks and sounds great, but how come the rattle is so loud inside the cabin if the source is up in the top of the door itself?

I just don't want to fix something that isn't broken - ie. apply the right fix to the wrong rattle.

thanks
