Abstract
A leading or trailing arm vehicle suspension system comprised of a fabricated vehicle axle and a fully integrated beam casting providing bending stiffness to control axle windup and longitudinal stiffness to control axle position is disclosed. The beam casting is attached to the vehicle axle with a thru-bolt connection. The beam casting includes rack and pinion mounting attachment holes and also includes other built-in features providing efficient transfer of loads into the vehicle axle.
