A mounting for the road wheel of a vehicle includes a hub, a suspension system component, which may be a steering knuckle, and an antifriction bearing located between the hub and the suspension system component to enable the hub to rotate within the component. The wheel is bolted to the hub, whereas the suspension system component is attached to the frame or unified body of the vehicle. The bearing has an outer race in the form of an insert that is embedded with the suspension system component. That insert is formed from a bearing grade steel, whereas suspension system component is formed by casting a different metal around the insert. The insert may also be within a hub that rotates on an axle. |
