Rockshox Zeb bushing play, knock and creak | Mountain Bike ...
· The bushings have lots of slots in them unlike previous rockshox bushings I've seen, did some googling, looks like a tactic used by fox a while ago, " hydrodynamic lubriion", ie have the bushings a little sloppy then rely on a build up of oil film to take out the slack, considering this, I have since reassembled with fresh oil and left upside down for about an hour.
