ABSTRACT:
A differential drive gear assembly including a differential case driven by a transmission allowing differential rotation between a pair of output axle shafts and facilitating a driving connection to a power take-off unit. The differential case has gear teeth directly formed thereon along an outer peripheral surface. The differential case gear teeth engage a power take off gear to drive an auxiliary device. In the preferred embodiment, the power take of device is a second drive shaft for driving a second axle assembly. Such an arrangement facilitates a simple conversion from an existing two-wheel drive design to a four-wheel drive assembly.
