Okay, jack the front of your lude up and you will notice that if you rotate one wheel in one direction, the other wheel will turn in the OPPOSITE direction. With LSD, if you turn one of the front wheels in one direction, the other wheel will turn the SAME direction. Basically when both wheels are on the ground and moving, one of the wheels is really pulling the car but actually, the power is distributed to both front wheels so its all good. If I ain't explaining this very well, maybe there is someone else who can do a better job
