guys, this is so easy to fix yourself, stop fooling with the dealer. first remove the plastic piece from where the seat belt comes out (see K-mans article when he changed his seat belt, it is under cosmetic mods in the articles). to remove it you just pull up real hard, it will not break. then just pull it down the seat belt out of the way. then you will see a nut (about 15mm, just a guess) that tightens the B-pillar to the car. tighten this nut with an open end wrench, but don't over do it. I promise all the rattles described above are this problem and will go away after you do this. then just snap the plastic seat belt cover back. any questions pm me.
