ok if it will extend out in your hand the odds are the front axle can not lock internally into 4wd

these issue usually come down to the passenger side inner axle tip breaking or the spacer washer breaks and falls down and either physically keep the fork from moving when the actuator pushes it to lock the front axle

again the actuator is working as you can see it holding it in your hand the front axle side tube needs to come off and see if the washer broke or the axle tip causing it from physically being able to lock internally into 4wd
