I ran front and rear ARB's in my Super Duty but used the rear alone alot. A true locker in the front makes it a pain to make hard turns.

Rear is really the best place for a locker as long as the axle can handle one, most of those with TJs go with a front one because the D35 out back won't take it. With my Rubi I have selectable lockers front and rear, I use my rear on all the time, the front one only when I really need it to get over something or unstuck.

I have selectable lockers, if I had to choose front vs. rear I would choose rear. When you negotiate an obstacle choosing the right line is the most important part of it. When you lock you axles you lose much of your ability to steer. Locking the rear can make it tuff to stay on line, locking the front makes it much worse.

I have a Dana 44a (44HD) and am planning on putting a locker in it. Just as soon as I figure how to get the broken bolt out of the carrier....

ive had that problem before. drill a hole in it smaller than the bolt. get a tap and die set. find a die the size of the hole you drilled. heat the bolt like crazy with a propane torch. use the tap but turn it counterclockwise like you are making reverse threads. this will not only help apply force more evenly across the bolt but it wont be as tight in there and it will turn easier. hope this helps.

The rear will be more effective since load transfers to the rear when accelerating and/or climbing. This is the same reason why rear axles are beefier than front axles.

But any locker is better than none. . .

Traditionally if you did a poll, I think many people would be torn by this same thing. I am. A locker in the rear is great- no two ways about it. A locker in the front is great, although arguably not quite as effective as the rear due to weight transfer. But, you "shouldn't" notice a front locker at all when in 2wd. A rear locker will be noticeable a lot, and if it's tight and doesn't unlock much (a friend has an Aussie in his front 44 that doesn't disengage that much) or if you have a heavy foot keeping the locker engaged, your tires will wear badly and cornering suffers as the rear tries to push in a straight line, etc. This is dangerous in snow. My JK rear tires wear bad with just the limited slip diff. But, it does good off road- not as good as a locker, but if I were putting one in my JK it would be in the front and I'd just keep the LS out back. Of course, selectables are the way to go.

This is "the step" on the Charleaux Gap just north of Tucson. Fun scenic trail and for some reason this obstacle was eating rigs up that day! We had a broken D44 axle, a broken lunchbox locker, and it just straight out defeated several rigs that were locked front/rear and lifted. Turn your speakers down, my wife gets excited and doesn't get out on the trail much.


And just for kicks, here's Dave breaking a front 44 axle on the FJ on the same obstacle.


So, if it were me, a selectable in the rear (prolly first) for mild 2wd manners with an Aussie or selectable in the front. If the $$$ isn't there for the selectable in the rear, I'd just go straight for an Aussie in the front and skip the rear- for now. All of course is just my opinion, but a front locker would've helped tremendously on the above JK video where a rear locker might not have. My LS is tight and performs well. Either way, a locker is better than no locker for off road use.
