should be able to pull the actuator out and test it to make sure its operating properly, you can also hear it pretty good if you get down there and listen. I have the cable actuated diff so Im not sure the difference between the actuator with diff lock and without. My actuator only controls the 4x4
You could pull out your front axel, passenger side, and look in there and make sure the collar is moving when you throw the actuator. In my case everything checked out, I pulled my axel, inspected, and put it back in and everything works, I suggest you do the same. I would say your axel may have popped out and is not engaging the collar inside the diff.
