The driver side window in my 03 Screw FX4 quit working awhile back so I replaced it today with a motor I bought from O'Reilly's. It went in fine, and the speed of the window going up and down is great, but the thing vibrates the door panel and seems to hum louder than a factory window. I removed the motor and replaced it a number of times to make sure I had it lined up good. When the motor is not in place on the track it is quiet and sounds like a small electric motor should. The sound is not noticible when you put the window up or down while driving down the road, but it is a little annoying if you are idling. Oh, and lubed all of the tracks and gears also. Any ideas would be appreciated.
