I have a limedslip in mine that is not it but it dos look like is dodge chry. and some jeep did get the powerlock witch I did have in my dodge for a wile.and they do work good and easy to rebiuld. but if it is making noise do the lub thing first becouse they do need the additive in the oil/greasr to work right. if you are driving in mud ,sand or hard on the gas pedle it is good it works by faster or harder you wheel spin the titer it locks up so it is easyer on tires onthe road than a locker.
