Abstract
An auxiliary axle or lift axle is pivotally mounted to the frame of a vehicle for selectively providing additional flotation for the vehicle. A pair of frame brackets are secured to the frame members of the vehicle and have horizontally disposed mounting plates adjacent to the lower ends thereof. A bracket member extends downwardly from one end of the mounting plate and has a pair of spaced-apart slots formed therein. A bracket member also extends downwardly from the other end of the frame bracket and has a pair of spaced-apart first and second slots formed therein. The hanger brackets are adjustably secured to the bracket members to permit the axle assembly to be mounted on frame members having varying distances therebetween and having varying frame thicknesses. The novel method of securing the hanger brackets to the frame brackets is also disclosed.
