A clutch for a Rear Drive Unit (RDU) selectively couples one of the half-shafts to an intermediate shaft. The clutch is actuated with a ball-ramp mechanism having a plate that rotates in response to rotation of a motor. In order to provide precise control of clutch torque capacity, a high gear reduction is desirable. Gear reduction is provided by a planetary gear set located co-axially with the clutched half-shaft. In addition to providing a relatively high gear ratio, this is more likely to fit into the available space without interfering with other components.
