    So, when doing some wheeling in the past I ran into. Situation where it would have been really nice to have a front diff that wasn't open. I read up on Aussie Lockers and it seemed that it's a great choice for the front. It's unnoticeable in 2wd but when you get slippage in 4wd it kicks in as necessary.

    Anyway, my research showed that as of a few years ago there were no 2nd gen applications but they were "coming soon." I haven't found and recent threads regarding this and don't know enough about diffs to decode some of the other stuff I've read, but are these available yet or still no dice?

    Did you have your A-Trac engaged? I am still learning how to use all the goodies that came with my off road 4X4, but with the rear locker and the A-Trac engaged, you have a limited slip front that makes the guys with the sports jealous.

    Scooped hoods get stuck, off roads don't. :notsure:

    Wow, bummer. A-Trac is a great feature and one that is pretty useful is you off road at all.

    yeah.... missed it by one year for you... A-Trac is sick, way better than any mechanical lsd or standard brake actuated lsd (like the default auto lsd).

    Either way, if you are going to the point of a locker, do it right, go ARB so you have a selectable locker in the front.

    I have an Aussie in the REAR of my '82 and like it and am considering putting one up front but that's with a solid axle and not a daily driver. I'd put a limited slip in the front of a IFS rig. Some bias would be appreciated when in 4WD. With my '82 I can shift quickly in and out of 4WD but with the modern rigs the electronic BS seems to take a moment ( maybe a moment too long?) I've rebuilt the front axle on my '04 4runner and I wouldn't put a lot of strain on those components.

    So a limited slip in the front would be my choice.

    You're correct, until 4WD is actuated the Aussie wouldn't engage.

    My Taco is a 6-speed so if I'm not mistaken I wouldn't have gotten A-Trac anyway...

    As I understand it you get less stress than a fully locked diff with an Aussie under most conditions - the front tires of a vehicle rotate more (faster) than the rear tires of a vehicle when the vehicle is not going straight (otherwise it is the same, obviously), and the Aussie locker allows the tires to spin faster, just not slower...so the locking wouldn't even engage until I experienced some slippage.

    I don't want to do ARB because of the cost and added complication...

    Your only option is ARB right now. I run mine off of nitrogen. It's really simple, and works every time. You don't even "need" any electrical switches, just set the regulator to 90 psi and turn the bottle on and it's locked. The switch it comes with is pretty handy though, as it vents the gas and turns it off instantly. It is at least 100 times more reliable than the factory elocker. :D

    That's not entirely true. They didn't call it that till 09, but mine has the exact abs ecu, brake setup, etc as the 09+ that have a-trac, mine is just called trac but functions exactly the same. (well, did until I cut all the wheel speed sensor wires)

    It's my understanding that mine is a bit of an anomaly though, it was purchased in an overseas market so who knows if that is "normal" for 05 trd offroad models with the 6 speed manual.

    Pretty sure they changed the master cylinder to the electronic assist style for a trac.

    I answered the question before going off topic. ARB. I don't know of any other locker available for our trucks. If you are wheeling in places where you need a front locker a lot, maybe you should consider throwing a solid axle under there. That opens up a lot of locker options. You could also weld the spider gears and just use your A.D.D. as a locker, but that is pretty ghetto.

    Yes, and I have the A-trac style master cylinder. I don't have all of the brake stuff on the passenger side, it's all at the master cylinder just like the Atrac trucks. Weird, I know.

    hmm weird.

    One thing i see with the trutrac is it will be constantly spinning your front drive shaft (between front diff and t case) by nature of the way the trutrac works if i have read it right. even with the ADD sleeve disconnected the still connected side will spin the entire diff.

    It's not that big of a deal. Some FJ's are full time 4wd like that from the factory. My ADD is always connected and it hasn't hurt anything.

    true, but the FJ / 4 runners that are full time have a different tcase / center diff.

    I doubt it would cause issues just stating the fact. Either way id still stick with an ARB locker in the front.
