Front Differential Actuator
The front differential actuator is an electric or cable operated actuator that engages the central disconnect feature in the carrier of the front differential, resulting in 4WD operation.
There are two different types of actuators used; one is electrically controlled and the other is vacuum operated. In most cases, you will see the electric actuators on the full size models (K series) and the vacuum controlled on the smaller models (T series).
