Abstract
Abstract A knuckle assembly in which the upper knuckle, steering arm and brake rails are formed as a one piece casting and the spindle and lower knuckle are formed as in integral forging. The spindle is then shrink fitted into a spindle opening machined in the casting with the lower knuckle positioned correctly relative to the upper knuckle and then finished to receive a lower ball joint.
