Lockers/Limited Slip/Locking Hubs

Often new 4 Wheelers are confused about terms we use.  They sometimes confuse Lockers with Locking (Manual) Hubs.
Lockers means you have a differential that applies power to both wheels on an axle regardless of a different resistance on that wheel.  Without lockers, if one wheel is off the ground the remaining wheel on the ground gets no power.  The wheel with the least resistance gets the power.  Limited slip Differentials do the similar thing.  Lockers and Limited Slip mechanisms are inside your differential.

Locking Hubs, when unlocked, basically disconnect the wheel from the axle so it spins freely.  Locking hubs are on the end of the axle.
