Good question, as it is not shown anywhere in the Workshop Manual.

There is catch tray in the top of the differential housing just above the ring gear. From there, another tray on both sides just inside of the top of the axle housing. When running forward, the ring gear throws oil up into the catch tray where it runs outward and downward until it passes from the open end of the axle housing into the interior of the rotating bearing hub. This is the space where you find the octagonal nut securing the wheel bearing.

Outboard of this space the hub is sealed to the halfshaft flange with a thin O-ring and paper gasket. As the rotating hub fills with oil, the oil runs inboard into and through the open ball bearing (not sealed). Inboard of the bearing the oil is stopped by the oil seal, which is rotating with the hub, sealing on the OD of the stationary axle tube. This allows the rotating hub to partially fill with gear oil.

When oil in the hub gets high enough, it runs back into the tube axle to return to the differential housing. This is a closed loop with forced oil flow when the car is moving forward. When parked, oil is puddled in the bearing hub and will stay there, as long as the inboard seal is not leaking. If you open the halfshaft flange for service, oil will drain out of the hub.
