Abstract
An axle disconnect assembly for a vehicle having an input shaft and a coaxially arranged output shaft. A collar is splined to one of the shafts and is slidable to selectively engage the other shaft to establish a positive driving connection between the input and output shafts. A movable piston engages the collar to selectively position the collar. A valve is in communication with the vehicle's existing oil pump and is controlled to selectively supply pressurized oil to opposite sides of the piston to selectively displace the piston thereby selectively controlling the position of the collar and the connection between the shafts.
