The rear chassis system includes a rear suspension frame coupled to a back rear axle. The rear suspension frame includes a bearing head with a bearing aperture. Equalizing beams extend between the front rear axle and the back rear axle, with each equalizing beam including a bushing aperture. The rear chassis system also includes a plurality of suspension mounts. To minimize relative translations experienced by the suspension mounts during operation of the vehicle, opposing end sections of a spindle cross member, along with the bearing aperture and the bushing aperture are coaxially aligned. Likewise, the opposing spindle end sections, the bearing aperture, the bushing aperture, and a top plate of each suspension mount are coplanar.",
