I'm sure there are people on here that can explain this better than me but I will try.
First off the "locking" hubs on the front axle only engage that side of the axle to accept power.
Open differential. Only 1 tire spins and usually is the one with least resistance. Not good if 1 tire is in the air.
Limited slip differential. 1 tire spins causing the other to start. Most common differential in vehicles. Still not turning both tires 100% of the time needed.
Locking differential. Both tires spin when power is applied. Examples detriot soft locker, Aussie locker. These are automatic lockers. Some are mechanical some are clutch. Electronic and air lockers are popular as well. These use air to force engagement which makes the axle feel as though it has a spool. These are great because they can be turned off when not needed. This leads to the next type.
Spool/mini spool locks both wheels mechanical. Not very nice for road and hard to turn. Used in drag cars.
Lastly is "Lincoln" locker. This is welding a open differentials spider gears together to lock wheels. This is done but I don't recommend.
If you have true lockers all wheels will spin.
