One interesting thing obout LSD, If u wanna confirm if your vwhicle is fitted with LSD just jack the back of the car up and spin one wheel. If the other side wheel spins in the same direction, its got a LSD, if it spins in the opposite direction, its a normal open diff.
This i found once while getting my car serviced, i found both the rear wheel rotate in same direction once service walla was washing the car from underneath.
LSD is not a simple diff, In a standard (open) differential, if one wheel loses traction, it will get all the power and will spin, while the wheel with traction gets nothing. The idea of a LSD is to prevent all power from being applied to only to the wheel that loses traction and to prevent from spinning freely.
Open differentials always work well turning. They also apply power very evenly when both rear wheels have
adequate traction. However, the big con is their torque balancing action when one wheel has much less traction, such as in ice and snow. One wheels spins and other remain stationary meaning your car is stationery and will require a PUSH or high acceleration until the spinning wheel acquire some traction
