Hello,
There are two ways of determining if you have a LSD. First jack up the rear of the car, with the shifter in neutral and the parking brake off, be sure to block the front wheels. Spin one of the tires by hand and observe the opposite side. If it spins in the same direction, you have LSD, if it spins in the opposite direction, you have an open differential. The second way is to crawl under the car and look at the tag on the rear passenger side of the differential. If there is an S in the numbers, it is limited slip.

good luck,
Dale Beuning
