I don't know how many of you have this, but I had a very loud sound like rain drops (no it wasn't raining!
) coming from the A pillar and just a ton of wind noise on the highway.
I finally got bored enough to look into it, and it was the black molding that holds the windshield glass in place. It was just laying on top of the glass, so on the highway the wind was lifting it up and making lots of noise. I glued it back down and the truck is much quieter now. Also, my back windows in my extended cab were making tons of noise and not secured in very well, so I glued those too!
I never used them anyways.....
