Four-wheel drive is really only two-wheel drive on vehicles that do not have lockers,

Not quite correct. If all 4 wheels have sufficient traction, power is divided to all 4 wheels equally & you have 4WD.

It's only when one wheel on an axle loses traction that most of the power to that axle goes to the wheel that can use it least.

If one wheel on both axles experience a loss of traction, then yes, you effectively have 2WD, but in reality, might as well be *no* wheel drive, because you ain't going nowhere <img src="/forums/images/graemlins/lol.gif" alt="" />
