ABSTRACT:
A one-piece steering knuckle assembly for heavy commercial vehicles such as trucks has a flanged body wherein the tie rod arm and in some instances the steering arm extend from the flanged body in a one-piece manner. The flanged body is constructed and arranged to receive a brake assembly thereon and the wheel spindle extends from the flanged body also in a unitary manner. In a preferred manner, the steering or the tie rod arms are forged to the flanged body through enlarged bosses which provide for connection to an axle by a king pin.
