For a few months now I'm the owner of a wrangler '91. This car is for me to play with and I really like it..
Now I want to have more traction, especially at the front wheels and saw that the aussie lockers is a great way to do this. I prefer the ARB air lockers, but they cost approx. 1500 USD per axle over here.
The thing that I want to know is that when you have this type of locker in your front axle and you switch to 4wd it will do his work and give traction to both wheels. And if you switch to 2wd it will have no effect on the onroad behaviour because my wrangler will disconnect the right axle, wright?
Is this correct or do I see this wrong, because I also want to drive my car on road
You are correct. It could get a bit hairy diving in 4hi on an icy road with the aussi or any kind of locker in there. But for normal driving in 2wd you will be fine.

i think it will dissconect on a yj as long as you have the two poexce right shaft but i belive you will still hear it when you turn and it might steer funny making left turns but im not a 100 percent sure i have a locked front and you can tell on the road hope that answers your question
But why do I need to switch it manual? the vacuum line does the trick already, or am I missing something?
I thought that when I switch from 4wd hi to 2wd hi the gearbox changes and the driveshaft in the front axle disconnects at the same time, or am I wrong?
What I do notice is that when I switch to 2wd the 4wd light stays on for some minutes. He never did that before. Does someone know what can be the problem?
4x4 Posi-Lok replaces the vacuum actuator with a cable operated actuator that puts the driver in control of the engagement from inside the cab. After engaging the transfer case, a one inch pull of the 4x4 Posi-Lok cable connects the right front axle to the intermediate shaft using the shift collar and fork, and 4-wheel drive is engaged! Simply reverse the procedure to disengage 4-wheel drive. 4x4 Posi-Lok also works great with lockers! When the front axle is locked, you can disengage the passenger side in order to make turns without wheel hop

You shoudn't notice a front locker in 2WD. As mentioned, if you put the Jeep in 4WD on snow/ice covered streets with an Aussie up front it could handle a little strange since the roads might be too slippery to make the locker unlock going around turns. This would be the situation where you might want to be able to manually unlock the right axleshaft to keep the 2 front wheels from fighting each other.
You are right that the axle shaft will automatically connect and disconnect when you switch between 2 and 4 wheel drive, but in a situation such as an icy road, you might want to be able to disconnect that one wheel while still leaving the Jeep in 4WD. This way the front left wheel will still get power to pull you through the snow, but you wont have the right one locked in to mess up the handling.
If the light stays on for a while after shifting into 4WD it could mean that the automatic vacuum disconnect on the front axle isn't disengaging right away for any number of reasons such as bad vacuum lines or the disconnect mechanism in the axle might be gummed up or it might be in need of new parts soon. Your Jeep will be in 2WD as soon as you move the lever, the light just means that the right front wheel just hasn't disconnected yet. Mine does this sometimes if i haven't used the 4WD in a while, but once I start using it again it turns on and off immediatly.
