A motor vehicle powertrain (10, 210, 310) having a rear driveline module (RDM) (20) for driving a pair of rear wheels (14a, 14b) and a method of assembly can include a hydraulically actuatable rear axle coupling clutch (28) operable to transmit rotary power between an input pinion shaft (22, 222) and a rear differential case (30, 230) and a hydraulic actuating assembly (16). The powertrain (10, 210, 310) can include a hydraulically actuatable differential control clutch (34) mounted coaxial to the rear axle coupling clutch (28) and a power take-off unit (PTU) (36) having a hydraulically actuatable PTU coupling clutch (42). The differential control clutch (34) can provide for speed differentiation between the rear differential case (30, 230) and a half axle shaft (26a, 26b) drivingly connected to the pair of rear wheels (14a, 14b). The PTU coupling clutch (42) can transmit rotary power between an input shaft operable to receive rotary power from a front differential case and an output pinion shaft (40) interconnected with the input pinion shaft (22, 222) through a driveshaft (18) in an all-wheel drive mode.
