Fabricated axles with a removable king pin are disclosed. The fabricated axles incorporate U-shaped channel construction. 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.
