I've from a few years a pair of Campagnolo Hyperon wheels which I use as my daily wheelset but last year it started to make (chain) noise in the rear.
The hub is the first generation with the plastic case (please see the picture at the bottom).
At first I thought it was a worn out cassette, so I replaced it, but no change.
I noticed that by holding the cassette on the edges it would move, so I tried to switch freehub, but the play was still there.
I took off the freehub and I noticed that the axle had some play; together with a friend I tried to adjust the play with the bold on the side but there's always a little play.
Once you put back on the cassette, there's still that latelal play of a few mm.
I understand that it can't be "locked" and there's must be a very minor play, but in this situation the chain would annoyingly tick like if it's not properly adjusted.
Before purchasing expensive kits like bearings etc, any first hand experience that might help?
Thanks.
