97-03 f150 front differential actuator


97-03 f150 front differential actuator, This is a clip showing the proper actuation of the vacuum-controlled actuator for 4x4 engagement as I move the 4x4 shifter back and fourth in the vehicle. This vehicle does not have any type of locking hubs. The axles are always locked to the wheels. The axle drive is engaged by this actuator. The smooth, back-and-fourth movement of the actuator proves that the vacuum selector solenoid and both vacuum lines are also working properly.
