A gear hub assembly is disclosed that has a sealed housing that includes an input gear and an output gear that are meshed together to provide a gear pump to move fluid between a fluid inlet and a fluid outlet disposed on opposite sides of engagement of the input and output gear. The housing defines an axle shaft-receiving aperture and a wheel spindle-receiving aperture to allow the gear hub assembly to transmit torque from a vehicle axle shaft to a wheel spindle while operating as a gear pump. The fluid inlet and outlets can be coupled to a hydraulic system to provide braking (or kinetic energy recovery) by restricting the flow of hydraulic fluid which in turn resists rotation of the gears in the gear hub, and thus can act to slow the vehicle.
