The axle actuator works together with the transfer case to send torque to all four wheels. The transfer case connects the input from the transmission to the rear and front drive shafts. Most of the time, the vehicle is in rear-wheel drive (RWD). When 4WD is engaged, the transfer case engages the front driveshaft. It’s still necessary, though, to connect the two front constant velocity (CV) axle shafts. This is done via a front differential and the axle actuator.

There are a number of things that can go wrong to cause you not to be able to engage four wheel drive. Age, damage, and lack of consistent use are the most common reasons for these actuators to go bad. These actuators need to work in a harsh environment. Underneath the truck attached to the drive-train, they are subject to extreme temperature change as well as physical damage from dirt, debris, rocks, etc. The gas inside the actuator can leak out over time or from a fracture caused by road debris. Sometimes these actuators cannot function due to extreme cold weather as the gas cannot get hot enough to expand to cause actuation. Depending on your location and and lack of regular use these actuators may not be used for 9-10 months during warm weather. A little moisture penetrating can quickly cause a malfunction. Any one, or combination of these can result in your 4WD system not engaging or not staying engaged.
