    Assuming it hasn't been swapped, go to realoem.com, plug in the last 7 or the car's VIN and see what it should have.
    The car makes it possible, but the driver makes it happen.

        You did not give year, make, model, or transmission.

        Your question can most likely be answered based on that info.

            would it be an lsd? or more than likely not?

              That car should have a 3.73LSD. There should be a tag on the right rear of the differential with ration and an S for limited slip.
