So much for the previous garbage being spewed forth. Now the truth just set you free. Nothing like a little real world experience...

GoldenSahara00 Glad you took the plunge and installed one instead of listening to all the nay-saying and garbage.

forgedoffroad.com The Forged 2012 JKU has an Aussie in the front and factory limited slip in the rear. Personally, I always recommend locking the front before the rear in situations like this. If you're paying for a rehear and locking it at the same time, by all means- go selectable front and rear... but if you're only locking one end, lock the front. It'll help you to pull up and over the obstacles versus the rear simply pushing you against whatever is holding you up.

The Aussie WILL release when in 4x4, but it WILL be pretty loud. Further, if you get "steel balls syndrome" and start following rigs on 40s and 44s everywhere, it's almost guaranteed you're going to break something, more than likely an axle shaft, trying to keep up. As long as you can keep a level head (what fun is that, though?) you'll be in great shape with the Aussie. My personal preference is to pop it back down to 4x2 when not on an obstacle so I don't have to hear the popping every time I turn. With the Riddler diff cover I literally can't here any clicking from the locker at all while driving on the streets.

We sell and install a bunch of Aussies on the JKs because they're the only automatic "lunchbox" locker, not requiring a gear reset. They're great for the average mechanic (we recommend purchasing a decent set of feeler gauges and a dial caliper so you can be confident it's all set up properly) and incredibly functional.

Further, Aussie carries a no-tire-limit warranty, so even if you're running 37s and the locker breaks, they'll repair or replace it for you as long as it was installed properly.

We urge customers to install Spicer 760x joints while you have the axle disassembled for the Aussie install. It's the perfect time to replace the worn out factory U-joints and even better to upgrade while you're in there. We keep them all in stock; if you'd be interested, feel free to hit us up and we can set you up with a package deal on the Aussie, 760X joints, and maybe even a LubeLocker to help keep the installation as clean as possible.

I guess that makes some sense. If you're going to lock a D30, might as well keep it cheap. If you go with an ARB, you're far exceeding the value of the whole assembly.

What are you running in the rear?

Pardon me. I'm not trying to discount your personal experience, but let me state a couple of facts that may be applicable. In your Blazer, you may have had the older version of the Detroit Locker and if so, I agree with you. 20 years ago, I had the old version of Detroit Locker in my front and rear Currie Ford 9 Inch diffs on an '89 YJ. That front locker behaved exactly as you stated. The newer versions of the Detroit now named "softlocker" are an entirely different animal and perform great in terms of driveability.

As for lunchbox lockers, I like them, but the weak link then becomes the stock carrier. A full Detroit is as simple and strong as it gets. If you add a front locker and upgrade your shafts, then the weak link becomes your U-Joints. I would much rather break a U-joint because they are cheap and easy to fix.

I was referring to tight trails to where you have limited room to turn around. But an auto locker will lock up when power is being put to it so turning is not as easy as when you don't have it in 4x4. I don't know about the Aussie or lunch boxes in general, but most of the autos I have been around are slow to let loose. That's why I made to post about the fact that I missed the lunch box part in the OP. Two different animals

WatchThis! Oppen diffs are extremely hard to break shafts in compared to locked difs. If it is oppen and spinning the torque will go to the other tire when put in a bind. If locked and put in a bind something has to give.

Personally I have seen a much larger number of shafts snaped/ twisted while crawling then spinning up something. If you are crawling you tend to have more traction transferring more torque to the shafts. Unless you have wheel hop and keep in the throttle of course.

There are tons of ways to break shafts.

And you seriously think locking one up will not make it weaker and prone to damage when wheeling? Having an LSD or oppen diff allows a wheel in a bind to stop before something breaks. This will not be allowed to happen on a locked axle so it is way more prone to breakage. And believe it or not, not everyone enjoys making 15 point turn arounds on a tight trail.

Simple facts here and something that has to be considered when thinking about an auto locker in the front.

Also remember that you almost cut an axles strength in half by locking it up.
I'm still fairly new to wheeling. I was told from the very beginning that a stock JK needed a locker up front versus an open diff for several reasons --

First, because when you lose traction going uphill in loose gravel. All power goes to the spinning wheel or the wheel in the air. So a fully locked front (with an Aussie) means at least 1/2 of the power is going to the wheel with traction. That's a good thing, not a bad thing.

Second, it was also my understanding that a front locker makes a broken axle (e.g., Dana 30 in my stock JK) less, not more likely to break. When crawling up a hill, and encountering some loose uneven rock and gravel, an unlocked front might have a highly spinning wheel in the air, and if it lands on rock, THAT is the most risky moment for busting and axle. If locked, then the wheel is spinning at the rate of the wheel with traction and the likelihood of axle break is much lower. The principle being, when a spinning wheel and a rock come in contact, the rock always wins.

Comments or disagreements?
07-09-2013 09:56 PM
WatchThis! Never said the axle shafts got weeker. I said axles locked up are more prone to breakage. Looks like another case of misunderstanding. Happens easily on forums. Same as confusing posters comments.
07-09-2013 09:52 PM
GoldenSahara00 I have an aussie not a soft lock, that was another poster. What offended me was when you called me childish and made assumptions that I was talking about you when I wasn't. The comment you made about axle shaft strength was wrong. The shaft strength is the exact same, but you are more likely to break a shaft. I know that's what you meant but some people are going to take that literally and that's not the case. There are a lot of factors that go into shaft strength and how/why a shaft breaks, and what conditions cause this. Billavista has some great articles on Pirate about it.

The kinds of wheeling guys with their first lockers on stock axles with mildly modified rigs will do is not going to see much of the steering impairment you see with a lunchbox on a rig on 40s. Lunchboxes aren't really strong enough to run those kinds of trails anyways. That's why they make full case lockers.
07-09-2013 09:14 PM
WatchThis! Do tell were the smack talk was. Isnt the whole point of a discussion to talk about the good and bad of something? Not just the up side of things and pretend the down side does not exist.


Maybe you should reread all my post without the butt hurt attitude. Ever thing I have said is a fact. The little smart as comment about wanting to know how a locked up axle is weaker over all tells me everything I need to know.

Besides isn't the softlock in your TJ a full carrier not a lunch box? I might be wrong but I thought it was.

Thinking some one does not have experience because there opinion does not match yours is a little childish don't you think? Sometimes some people don't have the option to stop and then turn the wheel, having to turn the wheel while driving is where it can be a pain in the butt.

Of course if you are running non agressive tires its probably not really an isue at all.

When the hell did I even say you didn't have experience? I said some people, not you. Quit flaming.

Where the hell am I stopping and turning the wheel? The one video I posted is fluid continuous driving over the rock. No issues.

Just like you I don't post or take video of everything I do. I posted some simple trails to show basic handling for the people asking about it.

I posted those videos in response to the poster who asked about the behavior of an Aussie from someone first hand. Not to try and continue a pointless argument with you. This thread is about talking smack on the downsides of a lunchbox. It's about the driving characteristics on and offroad. Now why don't you get the hell out of here if you aren't going to contribute in some manner instead of just running your mouth? It gets old pretty damn quick man.
07-09-2013 07:51 PM
live_slow Everything is a trade off.

You get an open D30 or you get a D30 with an Aussie locker in the stock carrier, and that is (or was) considered the limiting factor in terms of strength.

However, an Aussie locker is probably the most cost-effective way to lock up an open front diff., probably under $300. I think the most cost-effective way to lock up the back of an open daily driver is the Eaton Truetrac. The electronic and air systems are a bit costly. I wouldn't run a lunchbox in the rear diff of a daily driver, based on my own experience with one in the XJ.

DitPun Wow, those videos are incredibly compelling; thanks for posting them, GoldenSahara00. My biggest fear was losing the ability to steer in narrow confines, which can be an issue with selectable lockers. However, it sounds like because of the limited differential action that the automatics offer, it may not be as bad. I'm interested in the Aussie locker because I'm confident of my ability to install it. Let's just say the installation instructions for the, e.g., Detroit were intimidating! I think I'll give it a shot and post the results! Thanks for the feedback!

I have a Sport, but swapped in a Rubi front D44 with OEM locker. The locker is great when needed. However, when engaged, turning is difficult. You can pretty much only steer while your moving. I have had many times when a spotter is yelling at me to turn. I have to tell them the front is locked...

That said, the obvious question is: WHY ARE YOU LOCKING THE FRONT? LOCK THE REAR FIRST if you haven't done so already. I put an ARB in the rear, so use that most of the time. Only use the front when absolutely necessary. The rear is a D44 so is worth building unlike the front D30.

Never put a locker in the front unless you already have one in the rear. you can literally leave the rear turned on all day (off road) because it won't stop you from turning. With the front, it stays off most of the time.

And no, an LSD doesn't count. Maybe an aftermarket LSD, but the OEM one SUCKS BADLY.

Agree with this. I would never do an auto locker. Might be ok for ice, but not ideal for rocks and dirt.

jagerhelix I run ram assisted steering so it's a much different world on steering but I can tell when it's ratcheting to allow the axles to differentiate. On slight turns like working a line it will still be locked up, but if it's a u turn situation you will hear a clicking noise throughout the turn as it unlocks. I really like my Aussie. It really is one of the cheapest most effective mods you can do if you aren't locked. just take it easy on the skinny pedal.
