Abstract
A one-piece steering knuckle assembly for vehicles has a flanged body wherein the tie rod arm, hydraulic brake caliper bracket and, in some instances, the steering arm extend from the flanged body in a one-piece forged manner. There are enlarged bosses extending from the flanged body opposite the wheel spindle, the bosses having a bore which are axially aligned to receive a king pin. The flanged body, wheel spindle, tie rod arm and brake caliper bracket are all formed from a single steel billet as a one-piece heavy duty forging. Such a design eliminates the brake caliper/knuckle joint and the tie rod arm/knuckle joint, and thus, it results in savings in assembly time and weight.
