Can some plz tell me what the "#WD13 Voluntary Service Action - Info on Rev. Internal F. Race" refers to. This "recall notice" is showing up on a CarFax report for a 997 Turbo S that I may be interested in purchasing. Thanx in advance.

A search in google indicates this bulletin is for the center lock hubs and the interval for tightening.
