Axle assembly with hydraulically-operated disconnect mechanism and spin-on hydraulic filter

An axle assembly comprising:

• a housing defining a reservoir and a bore that extends through a first side of the housing and a second side of the housing and is open to the reservoir between the first and second sides;
• an input member and an output member;
• a clutch including a hydraulic actuator operable to selectively activate the clutch to selectively transmit rotary power between the input member and the output member;
• a pump including a pump body, the pump body being mounted to the housing, the pump body including a first inlet/outlet and a second inlet/outlet, the first inlet/outlet being in fluid communication with the reservoir and defining a first set of threads coaxial with the cylindrical bore, the second inlet/outlet being in fluid communication with the actuator, the pump being configured to pump a fluid between the first inlet/outlet and the second inlet/outlet;
• and
• a filter including a filter base, a filter port, a filter element, and a seal member, the filter port defining a second set of threads configured to threadably engage the first set of threads, the filter port being fixedly coupled to the filter base, wherein at least one aperture extends radially through an outer surface of the filter port and an inner surface of the filter port to permit fluid communication between the reservoir and the first inlet/outlet, the seal member forming a seal between the filter base and the housing when the first and second sets of threads are threadably engaged, the filter element being disposed between the reservoir and the first inlet/outlet.
