I would definitely pop open the gearboxes and give them a good once over, clean the gears off and the housings out, and then reapply some red tacky grease. There are a few holes on the outside of the housing that allow you to tighten the screws down, etc. Those holes do have the risk of debris entering, although it is rare that it is enough to cause more extreme sounds like those in the video.
