Another thing to consider with lockers in general is that to put them in your are going to have to screw around with your third members which for the front at least can be a nightmare and that is putting it lightly. Now would be a great time to re-gear your differential lower since you: 1)Have it out, and 2)Have it apart, 3)Are probably running bigger offroad tires anyway, and most importantly: 4)Don't want to have to screw with this stuff again . I have the Aussie front lockers and didn't put them in yet, even when I had all my front end apart because I am planning on going to 4.77s if and when I ever find some, and taking the third member apart twice didn't really appeal to me.
