A disconnectable all-wheel drive vehicle driveline having a primary driveline, a power take-off unit (PTU), a secondary driveline, a hydraulic pump and a driveline actuator. The PTU has a PTU input member, which is driven by the primary driveline, a PTU output member and a first coupling that selectively couples the PTU input and output members. The secondary driveline includes a second coupling that selectively inhibits power transmission through the secondary driveline. The hydraulic pump is configured to operate the first coupling but is powered by a synchronization event in which the second coupling is engaged so as to back drive the PTU output member.
