a vehicle drive train for transferring torque to first and second sets of wheels includes a first driveline adapted to transfer torque to the first set of wheels and a synchronizing clutch . a second driveline is adapted to transfer torque to the second set of wheels and includes a power disconnection device and a friction clutch . a hypoid gearset is positioned within the second driveline in a power path between the synchronizing clutch and the power disconnection device . the friction clutch and the power disconnection device are positioned on opposite sides of the hypoid gearset . the hypoid gearset is selectively disconnected from being driven by the first driveline , the second driveline or the wheels when the synchronizing clutch and the power disconnection device are operated in disconnected , non - torque transferring , modes .
