How does manual locking hubs work

The front wheel hub lock can be either manually engaged or locked automatically by shifting the gear stick. When the hubs lock, a portion of the engine’s drive power is transferred to the front wheels, making your vehicle a part-time four-wheel drive. This is essential as not all drive terrains warrant 4X4 performance. The process to this is complex, yet simple in explanation. When the shift lever is moved into position, the changing gear creates an inertia that "locks in" the hubs. When you "lock in" your hubs, you are connecting the two half axles to a drive plate that locks them together, making them turn as one unit.  · Just a basic over view. If your swapping hubs make sure you have the right hubs for your application.

We recently bought a Tacoma SR5 for work and fun out in the country. We can't get it to go into 4WD (well it's missing a front axle right now so 3WD). It doesn't actually have manual locking hubs ON IT, but it does have the studs for them. If it was missing an axle I am wondering if the hubs were removed also and just left off as well. Automatic hubs work on the same principle as freewheeling hubs without the need to exit the car to manually turn the actuator. Many newer 4WD's come with this as standard equipment. Very simply these units self-engage 'on the fly' when 4WD is selected within the cab. They are usually disengaged by reversing once 4x4 has been deselected. Most part-time 4WD vehicles have locking hubs on the front wheels. 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.

Front tires are rolling along - only rear tires are pulling. Red lines indicate rotating parts. In 2WD with locking hubs engaged front drive shaft, front diff and front axle, rear drive shaft, rear diff and rear axle are rotating. Front tires are rolling along (since connected to the axle, they make the front drive line parts rotate) - only rear tires are pulling.
