During a general clean up and lube I had my Fulcrum 5 Evolution rear wheel out and felt some notchiness in the freehub bearings.
For anyone interested...cost of a new freehub..50 to 60 quid.
2x bearings ?...I called in a favour but they dont cost that much.
Tonight's job...replace em.
Freehub and axle out.
2x 61901-2RS (6901 equivelent)
Flip out one seal from each bearing if you want to maintain the manufacturers spec..leave in of it suits.
Drive the outboard bearing out from the in-board side , this exposed some liberal amount of grease and a circlip holding the on-board bearing. Quite a bugger to remove the circlip (you need proper pliers) then drive out the second bearing.
New bearing fitted. Refit circlip, grease well inside, insert spacer, fit outboard bearing.
Avoid at all costs hitting the races or inner ring, I used a socket JUST smaller than the OD of the bearing so you'e striking the outer ring where no damage to the bearing will occur. Bearings weren't particularly tight.
All smooth now, took me maybe 3/4 hour, much of that pigging about with external circlip pliers instead of internal.
