Limited slip differentials of both gear and clutch types will transfer only a fraction of the available torque to the side that is not slipping. This is not as good as a locker, but may be enough to get you through. Limited slip differentials are not suitable for use in the front axle of a vehicle with an axle disconnect. When driving in a straight line the Detroit locker is normally locked. On dry pavement, when cornering, the outer wheel over-running the speed of the axle unlocks the outside axle shaft.
Power is applied to the inside wheel only.
This can cause a noticeable under-steer. Additionally, if enough power is applied while in the turn, the axle will lock up and the vehicle either slips wildly, spins or straightens out suddenly. This may also cause a steering jerk. When this first happened after the installation, we were expecting to see parts behind us since we didn't know what happened. We soon found this to be a normal charactoristic of the locker.
