Abstract
In a wheel bearing assembly, an outer surface of a head portion of a link bolt contacts an inner surface of an end wall portion of a constant-velocity joint outer ring. A shaft portion of a link bolt is press-fit into a penetration hole of the constant-velocity joint outer ring. An external threaded portion of the link bolt is inserted into the central hole of a hub spindle so that the external threaded portion protrudes from an outer end surface of a hub wheel. A lock nut is fastened to the external threaded portion, so that the wheel hub and the constant-velocity joint outer ring are linked, and the first spline and the second spline are meshed so as to be capable of torque transmission.
