Occasional rattle in back of cab

[Rankinroudy]

Had an annoying rattle coming from both sides. Turned out to be the seat belt attachment points for the shoulder. There is a piece of metal under the plastic trim that bangs against the sheet metal. Put some adhesive foam behind it and problem is gone! Had to finagle it in through the slot in the trim.

I had the same issue. adhesive foam tape did the trick
