I took it apart and I was missing 1/2 of the ball bearings so I just spaced them with an empy next to a full so the bearings were even. Also used waterproof axle grease.

I fixed it. Turned out the C clip had streched so I sanded the ends and now it rotates like a charm. The furller should last forever. Stainless steel. Hobie.com wants $250 for a new one. Ouch!
