REDUCED NOISE WHEEL HUB UNIT

A vehicular wheel hub unit includes a radially outer bearing ring, a radially inner bearing ring, and a plurality of rolling elements supporting the inner bearing ring and the outer bearing ring for relative rotation. The inner bearing ring has an axially facing metal coupling surface configured to frictionally engage a connecting surface of an element, such as a bell of a constant velocity joint, adjacent to the inner bearing ring, and the coupling surface includes at least one first region having a plurality of coupling surface ablations configured to affect an amount of friction between the coupling surface and the connecting surface. Also a method including ablating at least a first region of a coupling surface of an inner bearing ring.
