Abstract
A spring seat assembly and method of assembling the same reduces field failures related to existing axle and suspension attachment designs. The suspension is attached to the axle housing through an upper spring seat welded to the housing, and the upper seat is then supported by a weld-on lower strap to the lower section of the axle housing whereby the lower strap distributes the weld stress from the vehicle articulation into the lower channel. The upper spring seat and lower strap are subjected to a clamp load prior to welding.
