Ford F-250 Window Adjustment
This job started when my passenger window fell out of the track and into the door. The problem is that the track wears. The front track is attached to the wing/vent and can't be adjusted. The rear can be adjusted, but the factory adjusting slot is too short. Below the bolt is in the adjusting hole. Remove that bolt, and gently hold the window track mount away from the door while you use a tool like the Dremel cutoff wheel to enlarge the bolt hole. Make the hole a longer horizontal (side to side) slot. Cut the hole larger towards the front of the truck so that you can adjust the track tighter against the window.
