Jimbo - it sounds similar to your situation with having to muck about with the cones when you take the wheel off, what part exactly do you mean may be worn out - I didn't see any bearings racers as I understand the term?
the racers/races? are the groove in which the bearings sit. If they are machined properly and in good nick and the bearings are good it should be all smooth and lovely. If however, like my pretty much wrecked hub, there has been side to side play issues and the bearings have been wearing the groove down and deforming themselves and the groove then you just continue to get problems. to see if this has happened you take your bearings out, remove dust caps and clean your races. if they are shiny and lovely and feel smooth then good, if they are scratched up or have areas which look dirty or worn and feel rough and dont clean up then you probably have a problem.
on this subject I have a still good set of alexrims laced to my knackered hubs I think I am just gonna buy a pair of SJS sealed bearing hubs and some spokes and install those in place of my knackered hubs. does anyone see anything logically wrong with this proposal at first glance other than being time consuming and needing some wheelbuilding skills?
