a. Differential. The front differential provides the primary drive gear reduction. It is a single reduction

carrier and is manufactured by Rockwell. This carrier has a hypoid drive pinion (1) and ring gear (2) set and

a no-spin unit (3) in the differential assembly. A straight roller (spigot) bearing (4) is mounted on the head of

the drive pinion (1). All other bearings in the carrier are tapered roller bearings. The no-spin differential

unit (3) is contained in the differential case (5). When the carrier operates, the no-spin unit delivers

one hundred percent of the available power to both drive wheels, yet automatically allows normal differential

action when required.
