Can you polish the scratches out? Long ago I remember reading a recommendation to polish new hub racings by packing the hubs with some type of metal polish (started with the letter S, need help here guys), hooking up a drill to the axle with a piece of tubing and spinning the axle. After that you clean the races and rebuild the hubs with new bearings and fresh grease. Is it worth a try on the bad side?
