I replaced the hub, both bearings, release fork, all washers/wave spring/clips etc to be 100% safe. I'd bought it all in case it was needed and then just fitted it anyway
To be fair I did fit an RPS clutch and with a few of the horror stories floating around I wanted to be 100% sure the clutch was at fault if there was a problem. All perfect though so I guess you could call it preventative maintenance.
I have some AP Engineering aluminium bushes for the fork if you want to try them Kev. Made a huge difference on my car to the feel of the shift.
