jayharrell,
I never does "lock" that's an optimistic marketing type name. It is a clutch-type unit that has "variable" pressure applied to them. It is supposed to act like an "open" differential until one wheel spins a certain amout faster than the other. Then the pressure is applied to the clutches. The little teeth on the gear (bottom arrow) spin the shaft (upper arrow) which makes all of that happen.
I have heard that they are not too bad in the big 14bolt Full-Floater axles, but in the 10 and 12 they just won't last with any performance up-grades. More power and/or bigger tires can kill them pretty quickly.
