Abstract: 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).
