I have an annoying rattle over bumps coming from the piece of trim where the passenger side rear shoulder belt goes through. Has anyone removed this piece before? It sounds like something behind there has come loose or is rubbing on the trim. I contacted the service center and got an appointment for after the new year but between now and then i'm going to drive 2700 miles, so if I can just take care of it I'd rather just save the hassle. Otherwise I've heard the radio goes to 11.
