How do manual locking hubs work?
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.
What happens if you only lock one hub?
If you are in 4wd with one hub locked and one open the power would follow the path of least resistance and spin the unlocked axle unless you have a locked/spooled diff. In that case both axles would get power and only the wheel with locked hub would turn.

What are the benefits of manual locking hubs?

On a rear wheel drive vehicle (most 4wds) the rear hubs are constantly in a locked position and cannot be unlocked, also the diff is constantly engaged to the axles. When in 2wd (on a 4wd vehicle) with the front Hubs locked, 4×4 need to be selected for any drive to be transferred to the front wheels.
