An axle having a variable volume sump. The axle includes an axle housing that defines a gear chamber and a separate reservoir. The gear chamber and the reservoir are in fluid communication with each other via an opening. A regulator is located adjacent the opening. The regulator is operable to assume a first closed position that obstructs the opening when a temperature in the axle is below a predetermined value, and is also operable to assume a second open position that places the gear chamber and the reservoir in fluid communication via the opening when the temperature is above the predetermined value.
