A rear driveline disconnect apparatus for use with four-wheel drive vehicles that is configured to allow the driver to easily, quickly and reliably change the vehicle between a four-wheel drive mode of operation and a front two-wheel drive mode of operation. The apparatus comprises a housing having an adapter at one end that mounts to the vehicle transfer case and an output flange at the opposite end that connects to the rear driveline assembly. The shaft from the transfer case is received in the housing and engaged by an output gear disposed therein. A coupling mechanism selectively couples and uncouples the output gear with an output shaft that extends rearward to connect to the output flange and the vehicle's rear drive shaft. When coupled, rotational torque is delivered to the rear driveline assembly to power the rear wheels. When uncoupled, only the front driveline assembly and front wheels receives power.
