1. An electronic differential disconnect clutch, comprising:
a differential unit comprising a pair of splines arranged for receiving a pair of axle shafts;
a first flange comprising a first face spline, the first flange fixed to the differential unit;
a hub, rotatable relative to the differential unit and arranged to receive an input torque;
a second flange, rotationally fixed to and axially displaceable on the hub, the second flange comprising a second face spline arranged for engaging the first face spline;
a hub sleeve arranged to axially displace the second flange to engage the first face spline with the second face spline, the hub sleeve comprising axially extending fingers extending through respective slots in the hub and fixed to the second flange; and
a solenoid arranged to axially displace the hub sleeve.
