front diff actuator
First go buy some good penatrating oil. Remove the plastic cover to see the whole actuator. remove the rubber boot over the plunger. there are 2 C-clips one large one small. Remove both. Remove vacuum lines from the top of it (remembering blue on passenger side/red on drivers side) get a screw driver and gently pry the plunger off the little lever that goes to the diff and push the plunger back (to the passenger side of the vehicle). Now get a punch or drift and hammer it out of the housing
