I had noticed a lot of road noise from the passenger rear of my truck recently. I figured it was just seals shrinking or weatherstrip getting old. Today I closed the passenger rear door and noticed a rattle. A little checking revealed the screw holding the rear vent glass to the scissor mount was loose. A few turns with a small screwdriver and it was good to go. The other side was slightly loose. This is not a huge deal, but fixed a rattle and made the truck quieter going down the road.
