Mack Steering Knuckle
Should a steering knuckle at this position be forged to handle steering pivot loads and front-suspension weight? The Mack Steering Knuckle uses a forged body that handles those loads while resisting the fatigue cracking a cast knuckle can develop under repeated steering and braking loads. It accepts the factory tie rod end, kingpin or ball joint, and brake caliper bracket without modification. Choosing the correct side and axle rating for the Mack 20399428 keeps steering geometry and load capacity matched to the original knuckle.
