Abstract
A suspension interconnection assembly for a vehicle adapted to move along a surface of the ground includes an axle housing and a spring seat. The spring seat includes a pocket defined by a U-shaped saddle having a bottom wall that extends between a first leg and a second leg. The first and second legs include claw portions that are adapted to engage an upper portion of the axle housing. Welds secure the first and second claw portions to the axle housing so that areas of the axle housing adjacent the welds are in a state of residual tensile stress based on forming. The position of the welds provides a stress cancelling effect upon application of the load to the axle housing in a direction perpendicular to the surface of the ground.
