We have 2800 mi on our White Ind hubset. I've greased the pawls a couple times and replaced the o-ring for the freehub. During the second re-grease I found one of the pawl springs was bent-possibly my fault-and White sent me a new set and several spare o-rings free. Disassembly/assembly is very easy and only requires a small allen wrench which was supplied by my wheelbuilder (Speeddream). Bearings are still as smooth as when new.
Overall I'm very happy with them!
