I just rebuilt a Hadley hub and a teflon based grease was used to coat the pawls and ring gear. Originally the hub was pretty load now it is a whisper. Decided to look @ my WTB / Formula freehub - couldn't figure out how to dissasemble it so I shot grease under the seals - now it is smoother and quiet. Are loud hubs in need of lube ? I have several XT's that click like no tomorrow now I think they have no lube. What's the deal w/ freehubs & pawl maintenance ? Thanx
