Campagnolo had darn good tolerance stacks, so this is rare. We only had ONE hub that did that during the time I worked at bike shops, and a Campagnolo Distributor made good on it, (long gone Apollo TBS Distributors, wonder what ever happened to THIER inventory... they had Everything Campagnolo, high priced, but all small spares, all the time) but enough on the digressing.
The race Will "progress" slowly, and that will wear things more. So, I would carefully and squarely press it out or extract it, I have seen machinist brewed tools to do both, and then replace it with a new one (not worth it, at least to buy one) Or, clean the contact side of the race and bore of the hub shell with the Loctite goo designed for this purpose. I did this to an alternator end housing long ago and no problemo afterward.
