Aussie locker front or rear?

So to stay on buget I only want to lock one axel. I'm leaning towards a front locker. I figure I would have less locker hassel while in 2wd on pavement but still get all the benefits of having a locker while in 4wd in dirt.

Are there any advantages/disadvantages locking the front vs rear. I have stock Dana 30 and Dana 35 on 33inch tires, automatic and stock gears. I'm also pretty light on the gas pedal but just thought it would be nice to pick up some extra traction.

unless you have 1 piece shafts up front I would not lock the front 30 in a YJ. that's asking to break an axle shaft in a hurry with the stupid CAD system.

In general the front axel always has more issues when locked. There is a lot more going on up there with u joints and such with the steering.

I'm locked in the rear with a spartan and it works well.

I'd say lock the front. I have a Aussie in my d30 and love it! It does great. Don't lock a d35 if your really into upgrades on your jeep you'll probably swap rear axles in the future and it would be a waste.

Do an XJ one piece shaft swap and throw an aussie in it.

I have done the shaft swap and TJ seal for a total cost of 15 bux(got the shaft for free)

saving up for my aussie now.

edit- Im on 33's 4.10s 5spd 4.0 and i have a very heavy foot i blew up an open D35 with all terrains even with a light foot you will break the d35 if you put a locker in it

Spartan here as well for almost two years in a built D30 with Nitro chromo shafts. Advantage of a Spartan over Aussie/Lockright is ease of installation and larger springs/pins.

I wouldn't lock a D35. Open they're still not great, but locked *for many people* is a ticking time bomb. Some people get away with locking a D35, but many don't. If you're locking the front, find some TJ shafts from a stock TJ D30 or run chromoly shafts. Stock shafts can be had cheap. Chromo shafts will be a bit more, but they're not terribly expensive.

Which do you get more benefit from as far as a locked front or rear? My opinion and experience is a rear locker, however a locked front will still get you much further than running open-open.

I would not recommend locking a stock D35. If you want a drop in lunchbox style locker, I would recommend putting an Aussie in the front axle. It will be totally transparent while in 2 wheel drive on the street.

Be advised though, if you drive on snow much a lunchbox style locker can cause a lot of scary driving habits while in 4x4 with a front locker on snow. (Steering issues) The same is true if it's in the rear in either 4x4 or 2x4 on snow. (Fish-tailing)

I chose selectable lockers for this reason. I can turn the front or rear locker on at will. That costs more though... There's always a trade off.

I live in southern AZ so driving in snow would be unlikely.

I have an Aussie in my D30 on my YJ with the 2 piece axle shaft for over 2 years. No problems so far. Works great off road, not noticable on pavement at all. I love it and recommend it to anyone on a budget.

I know, I was thinking of that. Hey the pie place closed down last year. The lady passed away and her family just couldn't keep up with it

In your position with your stated requirements I would definately lock the front and leave the rear open.

I think I may do a front lock and look for a one piece axel to put in.

Any other opinions? I'll be checking in daily.

You'll never feel it in 2x4 anyway. TJs do not have a 2 piece axle, and many (most?) YJ drivers defeat the vaccum motor on a two piece axle eventually anyway.
