Abstract: A hydraulic actuation system (10) and method of assembly for disconnecting a secondary driveline (27) can be used in an all-wheel drive (AWD) vehicle (14) having a power take-off unit (PTU) (42) for transferring rotary power to the secondary driveline (27). The hydraulic actuation system (10) can include a source of pressurized fluid (50), a hydraulically actuated synchronizer (44) for synchronizing rotary motion between the PTU (42) and the secondary driveline (27), at least one hydraulically actuated clutch assembly (11a, 11b) for connecting and disconnecting secondary vehicle wheels (29a, 29b) with respect to the secondary driveline (27), an area control solenoid (ACS) valve (54) in fluid communication with the source of pressurized fluid (50) to modulate pressure to engage and disengage the synchronizer (44), and at least one variable force solenoid (VFS) valve (56a, 56b) in fluid communication with the source of pressurized fluid (50) to modulate pressure to the at least one hydraulically actuated clutch assembly (11a, 11b).
