Claim:
A vehicle drive train for transferring torque to first and second sets of wheels, the drive train comprising: a first driveline being adapted to transfer torque to the first set of wheels and including a first power disconnection device; a second driveline being adapted to transfer torque to the second set of wheels and including a second power disconnection device, wherein the second power disconnection device includes a clutch for selectively connecting separate portions of an axle shaft adapted to drive one of the wheels of the second set of wheels; and a hypoid gearset positioned within one of the first driveline and the second driveline in a power path between the first and second power disconnection devices, wherein the hypoid gearset is selectively disconnected from being driven by either of the first driveline and the second driveline when the first and second power disconnection devices are operated in a disconnected, non-torque transferring, mode, wherein the second driveline includes another hypoid gearset driven by the hypoid gearset and positioned in the power path between the first and second power disconnection devices.
