jack the truck up spin the rear tires by hand if they spin the same way then you got it..

if you spin one forwards and the other goes reverse you dont

There should be a tag on the rear diff.
If it has 3L73 then it has the LS
If it has 373 then it's an open diff.
I am using the 373 as an example, you gears might be different.

Nope means only 1 tire spins you have an open diff.

http://en.wikipedia.org/wiki/Limited_slip_differential

Quote:
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely– the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use however, such as driving off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.
So basically when your truck is in this position (imagine you're going up the hill vs down in the pic) a limited slip diff will not shift all its power to the freely hanging wheel, where as an open diff will take all the power to the hanging wheel; making you have no power to the ground and so fourth becoming stuck.
