Mine never did the binding, grinding, or chatering thing. Maby you should pull it apart and take a look at what is going on in there. The only thing mine would do is slipp when you got to the last 1 1/2"-2" of ice, or if you pushed down on it. I had oily stuff on my clutch pads, and the outer clutch housing. I cleaned them up and it woks GREAT now. %100 Better,
thanks all for the info
