A wheel bearing and hub assembly lets the wheel rotate on the vehicle and provides the point where the wheel mounts. A humming or grinding noise that changes with road speed, or play at the wheel, are signs this part may need replacing. Diagnose the cause first. If a worn bearing is the cause, this assembly replaces it.
