I have an Aussie Locker in the back of my YJ, part-time 4WD, 31" TrXus MTs. I don't bother with 4WD on the road or city. On icy side streets the rear end wants to step out any time there is a hint of a turn, it does this much more easily compared to when it was an open diff. I'm careful with the gas but I like it to drift out and then I counter steer and keep it slidin' just for the fun, of course no parked cars around to hit :lol: Would your wife enjoy the same antics? If so, enjoy :!:
