6 1/2 half years on my CK hubs. Totally neglected, only 3 services and ridden with play for a few weeks at a time and still on the original bearings. What worries me slightly is that you say you had to have them serviced to remove play on the hubs. Did your LBS do a full service in that instance? If they did they're taking the piss, because play is a 'known issue' on CK hubs. Getting rid of it is a 5min adjustment job. When I say known issue, I mean that a while after servicing they might require readjustment. Could you post a clearer pic of the damage? As for replacing, the whole hub wouldn't need to be replaced. only the driveshell, so I don't understand exactly why it's such a big problem. I cannot believe that CK themselves would not want to sort this out. They have an outstanding reputation abroad for looking after their customers.
