here is what i have done to several ext cab's back windows to get rid of the wind noise. first i popped the window arm loose from the latch assembly>>
you can see it still touching here. i pop mine loose with a phillips head screw driver while opening the window.

then i pull it outward and have someone hold it. i drill a small hole in the base of the latch. then i drill a smaller hole in the frame of the door. enough for a screw to start.then i install a screw in the holes and tighten ever so slightly. it only takes about a 1/4 turn and then you are done.

i hope this helps. i can get some better pics if needed.

i also posted this in the tech section. i put it out here so more would see it. if this thread gets moved or deleted then go to the tech section. good luck.
