No, the LSD engages itself automatically based on the amount of wheel slip between one tire and another. They won't engage through regular turns because the outside tire isn't really spining that much faster than the inside tire, but in mud/ice, one tire will theoretically spin much faster than the other, causing it to engage. However, if both rear tires are on ice, and both spin in place equally, causing the truck to go nowhere, the LSD will not engage, but you wouldn't notice it in your rage of being stuck.
I believe most LSD systems are based on centrifugal force, but I'm not 100% positive. Anyone wanna correct me on that?
Nothing special. Yet...
