back to the original question here. so far in all of these posts no one has mentioned the fact that putting only one locker in is usually not the greatest idea when it is installed in the front end. when climbing a hill, most of your weight is being transferred to the back, making it the most effective place for a locker, not to mention the fact that the driveline components are much stronger in the rear. if i were to only run one locker (which i see happening in the near future) i would definately put it in the back. I can attest to the difference that it makes.
