When I first bought the truck I noticed at higher speeds the windshield would make a really strange noise that seemed to be coming from the passenger side of the windshield. Almost sounded like it wasn't put in correctly, and the sound got worse. Then one day I went to drive it and I noticed a crack coming up from the passengers side in the bottom corner. It had just become visible because it had creeped up past the tint barrier thats around the edge of the window. Well, within a short time it managed to creep up and then spider out across the middle of the passengers side viewing area, exceeding the center of the windshield.
