Yep for certain.
My experience with the front lunchbox is it turns great in 4wd. No problems at all. Turns as good as stock, not even kidding.
Then when I locked the rear, my steering went to complete crap.
With the rear locked it wants to push you straight. Locked in the front and open in the rear and its very easy to turn tight lines.
Just my experience.

I had my rear axle locked first on my XJ, for no other reason than I bought an axle with one already installed. Our trails out here can get super sloppy and the mud is greasy. They're typically wooded with ruts, stumps, rocks, and hill climbs tossed in. I tend to bomb around in 2wd for a lot of stuff and only switch to 4wd when needed. I find the rear locker gets me around pretty well.
My F150 is locked in the front only and the steering wheel does rip out of your hands at times. It's also a pain trying to steer it in 4wd, so I'll drop back to 2wd, which can cause some problems (I have the same issue in the XJ locked front/rear). I can't bomb around as much in 2wd as I do in the XJ, so I'm flipping between 2wd/4wd more often.
I suppose a lot depends on your terrain as to which would be better for you and driving style/experience. I don't think I'd spend my money on an OX locker though.

we already answered your questions. you're not listening
you're the only one who knows if you need to install a locker in the rear. the reason for a rear selectable is to disengage it for the street use + turning radius when unlocked. reason for the front selectable is easier steering, use of 4wd in snowy road conditions, + better turning radius offroad (among other reasons for getting full case/selectables).
if you install a front locker and you're still getting stuck then possibly yes you need a rear locker as well. which side should you put your one selectable if you can only afford one? you decide for yourself. both have their own argument
what you're not thinking of- do you want gears? the D30 has a carrier break. so whatever full case locker you get will come in 2 gear ratio options. so you have to decide if you want gears now or forever hold your peace if you get a front selectable. (it would be stupid to not do gears at the same time)
what were trying to tell you is that you don't need to spend a couple grand to go drive through some mud holes in florida

I personally run an aussie in the front and a spartan in the rear, on 35 inch mt/rs. I dd it a lot. The lunchbox in the front is literally no different than stock in 2wd. And in all honesty the rear lunchbox only made a small difference in street driving. Sure, if you have $2000+ for selectable lockers and gears. Do that. But it is not at all needed. I understand the "fear" and confusion on locking. But trust me, a lunchbox in the front is a much better buy
Wasnt talking about you. I was talking about the two guys who posted above me. Secondly I don't just drive around in mud holes. I plan on turning this thing into a crawler at some point. Its kinda insulting when you say that because if there is one thing I hate its mud. I like trails not running through some crappy mud hole. And you keep mentioning Florida? What does that have to do with anythin? I live in florida but right now I'm in texas. 3
Secondly, I agree with Atmos. I see no reason to put selectables in stock axles that you clearly stated you have only needed for one mud hole. What Atmos is saying, before you going dropping over 1000 on a selectable locker, put an auto locker in the front axle (Dana 30 Lokka $198) and see how it goes. 99% of people say it handles exactly the same as stock in 2wd (because its unlocked).
So you are out a couple hundred if you don't like having the front locked or when you build this into a crawler and swap the axles. Atmos is just trying to save you some money.
So in conclusion, if your money is bountiful buy selectables because its your money and you can do what you want. If you want to save some money, buy a Lokka and enjoy until you swap your axle or need to upgrade.

Conclusion: will be putting a ausie up front. And see if I even need one in the rear. If I feel I do I will put a selectable in the rear. The one mudhole was only on that one run. I have hd other things that I've been through and not made it because I didn't have a locker. Plus lockers were in my plans for this thing when I got it. Like I said rocks are in its future. I am listening and learning. Oh and if I do put a selectable in the rear I change to a d44 anyway.

scroll down a little on their homepage and the info is under "Aussie Locker?"

What about one of those cable-actuated lockers? They're cheaper than an e-locker or air-locker, but they are still selectable. I looked into these as I live in a snowy state and lunchbox lockers don't sound too good for using 4x4 on the road...
