4WD Hub Locking Actuator Symptom: The hub actuators connect the axle shaft to the wheel hub automatically when 4WD is selected. More accurately, they disconnect the axle and hub when the 4WD system is not engaged, reducing driveline loss caused by spinning an otherwise non-rotating axle. The internal diaphragm on these parts wears out from regular use, or cracks from lack of use, as well as poor internal lubrication. If your vehicle has these symptoms : Difficulty engaging four-wheel drive. Four-wheel drive becomes stuck. Four-wheel drive mode does not activate.You need to check and replace your 4WD Hub Locking Actuator in time.
