I currently run a lockright in my dana 30 front axle. Nothing in the rear....yet. Waiting for the aussie to stick back there. YES i know it probably won't come out till June 2015. :p

back in the day I ran a front Powertrax for a few months w/o a rear locker. It did alright, but since being locked both ends it is no comparison.

I would go with a front locker first. The reason being is that it will allow you to pull your front end up, and onto an obstacle easier than your back end can push you up the same obstacle. It's like forcing your front wheels to climb with no ability to really grab and pull.

That being said, a rear locker is better than none.

I am putting a Detroit in my D30 this spring and leaving the rear 8.8 open until I can afford double ARBs.

I am sure others may disagree, but for the wheeling we do here (lots of boulders and logs and junk) the front locker first seems to be the way to go. If you wheel in an area where there is more smooth rock and sandy soil, mud etc, I may be way off base.

To anyone thinking about installing an automatic locker in their front axle, I would highly recommend that you also install a 2LO kit in the transfer case. I ran a Detroit in my old front end for a while, and it only took a few trips out, having to make 3 and 4-point turns on the trails, for me to install a 2LO kit in my t'case. Having the front end effectively spooled when in 4WD made a huge impact in my turning radius, and not for the better. I've not got an ARB up front.

I have an auto in the rear, and I can see that what you're saying would be true. They don't give much at all, and having all four tires pushing in the same direction at the same speed would tend to push you in a straight line. I wheel in rocks, for the most part, and have been waiting to put a locker in the front when I can afford a selectable one. Until then, I'll keep it open. I can go pretty much where I need to anyway!!

X2, I have the same set up and would agree with the type of wheeling we do a front locker is great. You might not like the noisiness and drivabillity of a automatic locker.
