my power windows still work, no gaps or lag on the motor or anything, the only thing is both the windows when pulling down, shake and wobble. they still work fine, and work at same speed, its just so weird why they shake and shimmy on the way down.

Sometimes when i park on my driveway, which is inclined up a little bit, and i lower the windows, they work perfectly. i think the anglecorrects the issue somewhat. anyone have any experience with this? i tried lubing the tracks and everything but doesnt seem to work......

 

I have that problem since i bought my truck 4 years ago. Matter of fact just today i put a new window regulator/ motor combo in because my driver window wouldn't go up all the way and leave a quarter inch gap once it reached the top. Now with the new regulator and motor i don't have that wobble anymore. Maybe since i nut and bolted the new regulator in and ford uses rivets to hold their regulator in.... That maybe the problem
