I noticed today that my cassette has a fair amount of up down play. It's done up nice and tight so it's not sliding in and out on the freehub body and can't be pushed in or done up tighter. It's around 2mm of movement at the largest ring maybe a bit more. Simply put you can wobble it.
I assumed that the freehub bearing is gone or could it be something more costly. It's a hope bulb.
It's engaging fine and works but something needs maintenance.
Any ideas?
Thanks
