So my brother in law bought a rock crawler at the mecum auction in Houston. The rear axle is not the original axle that was on the rig. It has been changed out for whatever reason. It is a Dana 70 and has a Detroit locker in the rear. The original axle had a ARB locker in it and all the air lines switches and everything needed is still there. Would it benefit us to take the Detroit out and go back with a air locker? Just looking for some advice from someone that knows more about this kind of vehicle.
