first off check to see if the actuator is working properly. next, pull that other little screwed-in plug thats right near the actuator and make sure that switch isn't stuck either. with both of them out, spin each wheel freely and make sure they don't bind. if they do, you might need to pull the pside axle tube off the diff and see if the little sprocket and chain in there are completely disengaging.
