Dirt, rust or worn parts inside the hub can prevent the mechanism from sliding in and lock the hub. Anything that binds the internal mechanism can prevent it from sliding and releasing. The most obvious symptoms may be increased fuel consumption, highway noise and/or increased front tire wear. When the locking hub does not work properly, you need to replace it with a new one.
This 4x4 front axle actuator is a direct replacement for the factory Ford actuator. Each actuator comes pre-lubed for easy installation on the wheel hub and axle assembly. Save hundreds off dealer prices and restore the function of your 4x4 system with a new locking hub.
Located on the front wheel hubs the 4WD actuators control power transferred from the axle assembly to the front wheels. This 4x4 locking hub fits both right and left front axles on your Ford F250, F350, F450Super Duty and Ford Excursion and Lincoln Navigator.
