This is more of a question than a query. I have just ordered an Aussie locker for my rear Axle, has anyone on the forum fitted an auto locker to both axles. I guess that as the front has the ADD then it should have no effect when in 4x2, but what will be the effect when offroad and in 4x4. I was recently watching an XJ Cherokee (also with ADD style front axle) with LS rear and Aussie locker front, awesome performance offroad, couldn't get to chat tho.
