Ok, that I am somewhat caught up on chassis problems, I am looking at this. So I pulled the cover off, and you'll never guess what I found.


Since it is still working properly, and doesnt look as bad as the guy's in the video above, can I just grind down the tiny teeth with a dremel tool?
 Also, the inner hub is tight, and doesnt move, just the basket and gear move together. Need to get a bigger socket to take it off, then is there a bearing thats shot back there? Im learning to love bearings with this thing.
