An axle shaft disconnect clutch includes a housing, an axle shaft, a stub shaft, a dog clutch and an inner race. The axle shaft includes a first outer spline and the stub shaft includes a second outer spline. The dog clutch has an inner spline engaged with the second outer spline and the inner race is rotationally fixed and axially displaceable relative to the housing to axially displace the dog clutch and engage or disengage the inner spline with the first outer spline. In some example embodiments, the axle shaft disconnect clutch has a bushing pad fixed to the inner race. The inner race is arranged to push the dog clutch towards the first outer spline to engage the dog clutch, and the inner race is arranged to pull the bushing pad to pull the dog clutch away from the first outer spline to disengage the dog clutch.

A two-piece seal assembly includes first and second seal subassemblies, each shaped as a semicircular ring. The first seal subassembly has a first stator subassembly and a first rotor subassembly that cooperate to form a first semicircular segment of a labyrinth. The second seal subassembly has a second stator subassembly and a second rotor subassembly that cooperate to form a second semicircular segment of the labyrinth. The first and second stator subassemblies, when affixed to each other, form a ring-shaped stator that encircles a rotation axis. The first and second rotor subassemblies, when affixed to each other, form a ring-shaped rotor that encircles the rotation axis and can rotate about the rotation axis relative to the stator. When the first and second seal subassemblies are affixed to each other, the first and second semicircular segments meet such that the labyrinth encircles the rotation axis.
