only one way to find out bud! start pulling that panel off. I JUST pulled the panel off my 05 because I too am getting a little rattle. Sorta like a thin peice of metal vibrating with lower frequencies. Im gonna add some raammat and ensolite to the door and panel. To take off the panel, just start pulling towards you from the top or side. Your gonna need a trim panel removal tool to get the push pins out though. When youre pulling them off...MAKE SURE THEY DONT FLY AWAY! I was taking them off last night and lost 3 of them because they came out flying. Ford wants $4 for each push pin!
