A combined coupling and differential assembly 100 for a vehicle 10 (fig 1) comprising; a differential 120; an engageable coupling 130; a common housing assembly 140; and a hydraulic actuation mechanism 150. The common housing comprises: an outer housing assembly 142 rotatable about a central axis by means of an attached ring gear 112; and an inner housing assembly 144, which drives the differential, is disposed within the outer housing and is rotatable about the central axis relative to the outer housing. The engageable coupling is arranged to selectively couple the inner housing to the outer housing, so that the inner housing rotates about the central axis together with the outer housing. The hydraulic actuation mechanism comprises: an actuator piston 152 disposed outside of the common housing assembly; and a thrust transfer element 154 to transfer force from the actuator piston to engage/disengage the coupling. The assembly is designed to engage/disengage the four wheel drive function of a vehicle.
