You can try lubricating it fixing it i don't think so as the ball is pressed in. Get a rebuild kit from S-K for it. Email them leave the model number your address and phone number you will get one in a few days at your front door at no charge. S-K has the best warranty in the industry. Besides Craftsman. Lol
