Abstract
A steer axle assembly is provided. The assembly includes an axle beam that defines a boss at one end. The boss defines one bore configured to receive a kingpin. The boss further defines two additional bores that intersect the kingpin bore and that are configured to receive draw keys used to secure the kingpin within the kingpin bore. The draw keys are both disposed on an inboard side of the kingpin. The assembly further includes nuts disposed about one end of the draw keys on the same side of the axle beam. The inboard location of the draw keys and the same-side location of the nuts reduces assembly time for the steer axle assembly and securely locks the kingpin within the bore.
