Abstract
A fabricated high strength non-driven steer axle is provided so as to be cost effective to manufacture, the axle having a limited number of parts and steps of manufacture, as well as being of a reduced weight. The axle includes an integral one piece metallic form having a substantially U-shaped central portion in cross-section, and a pair of spaced arms extending from each end thereof toward a respective king pin mounting area. In order to simplify king pin mounting (e.g. eliminate the need for a bearing sleeve or tube), a separate king pin reinforcing plate is inserted between the spaced arms so that each king pin is received through an orifice in the reinforcing plate and a corresponding orifice defined in another plate, both in a bearing manner so as to efficiently support the king pin.
