Most 4WD vehicles have locking hubs on the front wheels. When the 4WD is not engaged, the locking hubs disconnect the axle. They spin freely, and the rear wheels of the car do all the work of moving the vehicle. When 4WD is engaged, the locking hubs lock in the front wheels to the front axle allowing them to get torque from the engine.
Mud, rust or worn parts inside the hub can prevent the mechanism from sliding in and locking the hub. Anything that binds the internal mechanism can prevent it from sliding and releasing. The most noticeable symptoms may be an increase in fuel consumption, noise on the highway and/or increased front-tire wear.When locking hub can not work properly, you need to replace a new one.
