Canon EF-S 17-55mm f/2.8 IS USM repair autofocus hunting problem (cleaning the focus strip)

This video is about cleaning the focus strip of the Canon 17-55mm f/2.8 EF-S IS USM lens to repair the focusing problem. I had this lens which autofocus was hunting at the tele end. This problem was caused by a dirty focus strip inside the ultrasonic motor, so I had to remove the focus strip from the motor, I had to clean it, and then I disassembled the focusing motor and the lens. In this video I'll show you how I did that.
