Interconnected vents for a motor vehicle axle assembly, transmission or transfer case which interconnects multiple vents at different locations together with another vent positioned at the highest point the lubricant travels. This allows the lubricant to flow out of one vent and return to the other vent without leaking onto the ground. Such an interconnected vent arrangement will minimize the extent of external lubricant leakage due to such factors as foaming of the lubricant, air entrapment in the lubricant, volumetric expansion of the lubricant due to elevated operating temperatures, pumping or splashing of the lubricant by internal rotating or moving parts, flow of the lubricant due to tilting of the motor vehicle, and thus the motor vehicle axle assembly, transmission and transfer case, and/or acceleration or deceleration of the motor vehicle.
