| There's 4 pressure ports for axle lube and 1 lube return down below the input driveshaft.
Lube pressure is only 2-3 psi or so if I remember correctly. Other lines going into front side of axle can be hydraulic diff lock. Rear axle is sealed, with no outlet for air. Lube pump pushes a oil / air mixture through the rear end, and when it fills up far enough, the 2-3 psi will push it back through return port until air can travel again. Really simple system
