A bearing race is the ring that the bearing's rolling elements run against. As it wears, the bearing can lose its smooth rotation. Signs that a race or its bearing may need replacing include grinding, humming or growling that changes with vehicle speed, rough rotation, excess play, and pitting or scoring on the race surface. Because these symptoms can have other causes, diagnose the source before replacing parts.

A race is typically pressed into its bore. It is commonly replaced together with its mating bearing so both wear surfaces start fresh. Follow the vehicle service information for removal, installation and bearing adjustment.
