i got an aussie up front and what a difference, good thing. the only issue ive ever had, and mind you you ive sunk the jeep through lake christy, buried it in snow and wheeled it like it should, is if you hit a good patch of ice and the brakes with one wheel still rolling and one sliding it thinks youre losing traction and tries to engage with a rather unearthy sound. but thats with all auto lockers, i just happen to have an aussie. and for the price comparison well worth it.
