Abstract

A method for distributing load forces among axles of a truck having a front steer axle and two rear axles, the rear axles including an air suspension, includes the steps of monitoring a load on each of the axles and generating a load signal therefrom, increasing a pressure in a forward rear axle air suspension relative to a pressure in a rearward rear axle suspension to decrease a load on the steer axle, and decreasing a pressure in a forward rear axle air suspension relative to a rearward rear axle suspension to increase a load on the steer axle.
