  • Publication number: 20040145144
    Abstract: A front axle beam assembly is provided comprising a center beam portion having opposing first connections. Knuckles having second connections are secured to the first connections of the beam preferably by threaded fasteners. A spindle is pivotally supported on each knuckle by king pins. The center portion of the axle may be constructed from a material different than that of the knuckles. Moreover, the knuckles may be formed by a different process than that of the center axle portion. For example, the center portion may be constructed from an aluminum casting while the knuckles may be constructed from a steel forging. Different axle center portions may be selected depending on the desired track and suspension attachment points. Similarly, the knuckles may be selected to provide desired suspension attachment points for linkages, airbags, and/or leaf springs. The knuckles may be selected to achieve a desired axle beam drop.
