Theres lots of info if you wish to search for it, either here or on the web. But anycase a quick run down is as follows.

A "normal" diff is what is a called an open diff. In this case either of the driven wheels ( we'll stick with 2 wheel drive for now) can move at any speed with respect to each other. Generally if you jack up an open diff car and spin one of the wheels the other will spin in the opposite direction.

You can look at it as being a slip diff if it makes it easier, each wheel can slip past each other at different speeds with NO resistance. ( for all intents and purposes)

A LSD diff is a limited slip diff. In this case there is resistance to letting each wheel move independantly of each other, that is there is "LIMITED" slip. Thus as one wheel moves round it pushes the other wheel round, well the pushing happens in the diff but its seen at the wheels.

This counters the tendancy of an open diff to supply all the power to the one wheel that is spinning the most. This is easliest seen if you " burn some rubber" in an open diff. Usually one wheel will spin.

With a limited slip diff some of the power is transmitted to the wheel that is not spinning causing it to move as well, so both wheels spin. This in the real world translates into better traction and acceleration.

Scroll to the bottom of the page above. It lists your box as having a factory LSD.
