The freehub on two of my bikes are totally silent when coasting. The GT Talera has been silent ever since I bought it (used). I just noticed my Trek 1420 freehub became silent today. No more tic-tic-tic-tic-tic as I coast. Both bikes still work fine but I was wondering if this is a sign of future problems? Anything I can do to remedy?
Only thing that has changed is I recently cleaned and re-greased the hub bearings on the Trek. Did the same on the GT shortly after I bought it used but it was silent when I bought it in the first place.
