This rear axle is an integral design hypoid with center line of pinion set below center line of ring gear. Semi-floating axle shafts are retained in housing by ball bearings and bearing retainers at axle ends. The differential is mounted on two opposed tapered roller bearings which are retained in housing by removable caps. Differential bearing preload and drive gear backlash is adjusted by nuts located behind each differential bearing cup. Drive pinion assembly is mounted on two opposed tapered roller bearings. Pinion bearing preload is adjusted by a collapsible spacer on pinion shaft. Pinion and ring gear tooth contact is adjusted by shims between rear bearing cone and pinion gear.
