I'd like to know too.

They sound like Eaton E-Lockers by the way they function and operate, but I haven't seen anything to confirm this.

Actually, with a new brake actuated limited slip technology (a-la Toyota's ATRAC) you will need lockers much, much less.

Even the base JK will have this technology - and that will allow it to be much more capable then any open diff TJ.

Interesting question is whether Jeep engineers are better then Toyota's and allowed this traction control to work the front axis simulataneously with a rear locker engaged. That's the best combination - as traction control allows for much easier handling then a front locker.

Seriously, though, benthood22, here's some info on lockers.

http://www.4x4abc.com/4WD101/diff_locks.html
http://auto.howstuffworks.com/differential10.htm

Basically, when one wheel is off the ground, it would normally get all the power and would just spin, the other wheel wouldn't move, so neither will the vehicle. A locker locks the two halves of the axle so they spin together, so the wheel on the ground will get some power and your vehicle will go.

As Karamba said, Electronic Traction Control can also help get power to the wheel with traction.

Right. The drawback of ABS based traction control - it will only provide half the possible torque, and it lags - reacts only when a wheel is already slipping - so starting uphill, or crawling up a step is harder. Its advantage over a locker is it preserves steering, and you can just keep it on, without anticipating when you need it. Two quite complimentary traction methods.

why do they have to complicate things with electronic crap!!?? I say that the jeep should have 2 axles (mechanicaly locked) 4 tires and 1 motor (plus some more necesary components), and let the driver controll them, not some computer.

The WK has the computer controlled traction control system on it and last weekend in Moab it worked flawlessly going up things that people with lockers were slipping on...

Hells Gate @ Hells Revenge:



I was impressed with the system...worked great.

Actually the WK has more then just traction control, it has Eaton EGerodisc differentials. They work so well when I talked to the guys at AEV about building that Jeep they said they left the differentials alone, becasue they are better then ARB's. The PBS show "Motorweek" once did a test of just the differential (in a GC), and it was incrediable. I can't find the video, but they tested it off road, and on pavement with strategically placed rollers, so different wheels would have traction. The Jeep climbed uphill over any combination of rollers without even slipping a tire. It was all instantaneous.

Can you read? Those are two different systems, usable in different conditions, each with its own advantages. Once you got ABS sensors in place, making traction control is a matter of some clever code. As you are not capable of braking just one wheel just in time - computer does a much better job at that. And, yeah, it has the off switch.
