ABSTRACT:
A differential assembly that includes a differential casing, which is rotatable about an axis, and a pair of side gears that are disposed within the differential casing. First, second, third and fourth pairs of pinion bores are formed in the differential casing and pairs of pinion gears are slidably and rotatably disposed in a respective pair of the pinion bores. A window opening is formed in the differential casing between the first and fourth pair of pinion gears. The second pair of pinion bores are radially offset an equivalent distance from the first and third pair of pinion bores. The differential assembly incorporates a cross pin configured to limit inward movement of a pair of axle shafts and a spacer that limits inward movement of the side gears.
