It is the plastic rollers inside the gears. Just replaced them on 4 headlights. Gears were in perfect shape but I replaced with plastic gears anyway. The metal gears cost a lot of money. I would stick with plastic. My gears had zero wear. I could have reused them. I would have been pissed if I sprung the extra for the metal gears. The head lights also for some odd reason fail closely together so buy parts for both and use a good plastic compatible grease.
