mustang,before you go to the trouble of tearing apart your LSD, replace with Mobil 1, and a bottle of "friction modifier", the friction modifier is available at your mitsubishi dealer for about $8... we have two with LSD's... both chattered about on corners.. etc.. with a drain and refil of the rear diff, and refil with mobil 1 and the friction mod, all chatter is gone and LSD works MUCH BETTER... while you are at the dealer... pick up the aluminum crush washers for the rear diff...
