What does 4×4 actuator do?
A 4×4 actuator is an electronic device used to engage the front differential on a so-equipped, four-wheel drive vehicle.

How does an axle actuator work?
The Axle Actuator is a device which activates the front axle when the driver switches from 2 wheel drive to 4 wheel drive. When the switch is turned on, the control module turns on an air-pump which is mounted near the front of the car. The pump begins to build pressure and eventually opens a relief valve.
