I've raced mine for almost a year, and in that time it has has the following items replaced - er... nothing! It stays exactly as set for meetings on end without any rebuilds, and when that time comes it is usually because the track is very dusty. The dust seems to swirl around in the wheel and get itself in the thrust race.
A rebuild is simply clean and re-grease, I've never sanded a washer either! The clever part of the Corally diff that seems to make this all possible is the O-ring. HTH
That's the complete opposite of my experience with that diff, and six ball diffs in general (the larger axle bearings notwithstanding). A six ball diff requires a lot more pressure on the balls to keep the diff from slipping, and as result everything wears out faster. But if it's working for you, great, since the assembly is so much lighter
