Extensions of front and rear channel walls wrap partially around and separately join axle head plates which support a removable king pin. King pin fastener bores are partially defined by the head plate and by front and rear channel walls. The bottom surface of the head plate is received within an opening of, and secured to, the bottom plate which overlays the channel.

A tie rod arm is provided for incorporation into a vehicle steering assembly. The tie rod arm has a grease cap portion with a steering knuckle connection formation and a grease seal cap. The steering knuckle connection formation is used to connect the tie rod arm to the body of a steering knuckle of the vehicle steering assembly. The grease seal cap receives the lower end of a kingpin of the vehicle steering assembly. The grease cap portion of the tie rod arm is integrally formed with an arm portion, which includes a tie rod connection formation to connect the tie rod arm to a tie rod of the vehicle steering assembly. A steering arm may also or alternatively be connected to the body of the steering knuckle and include an upper grease seal cap, which receives the upper end of the kingpin.
