Abstract: An auxiliary axle assembly in which a pair of pivoted swing arms, each supporting a wheel are mounted to a frame member to extend downwardly and outwardly therefrom. Controllably pressurized air springs are mounted to a respective swing arm to set a desired level of the axle assembly when hitched to a loaded vehicle. The wheels swing on the arms to automatically align with the radius of a turn arc.
