Last month my car started to make annoying rattling noise coming from the front doors when i go over rough pavements. i was thinking about taking the car to the body shop and have them looked at it but i thought that would cost too much. so last week sometimes i kinda worked on my car a little and found out that the noise was coming from the old sill between the metal and the door panel. so i inserted small pieces of thin rubber (the same rubber you have to cut off when you buy the all season rubber floor mats) between the door and the door panel. The noise is gone. i'm very happy with it now.
