I went back and re-read your 1st post. I'm guessing you have the Quadra Trac II system. (QT II)
That's a full time 4 wheel drive system. All tires are driven, and torque shifts around as needed through three differentials. A differential has a set of gears which allow one tire to spin faster, such as during turns because your inside tire track circle is smaller than the outside track.
The system has braking traction control, which means if a tire slips, the brake's ABS system individually controls the spinning. In reality, a wheel/tire will "pulse" (start/stop) when it's up in the air. (I've done enough extremes to get tires hanging in the air) When climbing loose dirt on a steep hill, the system will hardly disturb the dirt. There's NO throwing dirt like older 4x4's.
Jeep has a system called ESP. (Electronic Stability Program) The computer has G-force sensors, and uses the ABS braking to control each wheel as needed. That's one of the reasons a Commander is so rock-solid on loose dirt or gravel, it can corner brake to keep you from screwing up.
You can't skid because IT will take over, pull the throttle away from you, (drive by wire) and brake individual wheels to keep you in control. (It also has steering input sensors, so "it" knows what you're trying to do) When the traction control or ESP kicks in, you hear a buzzing sound which is a rapidly pulsed braking action.
The drive-by-wire system will also remove your throttle input when needed on climbs, so even mashing to the floor, you can't spin the tires. You have to turn off the system before you can hot-rod off-road. If you're not used to what it does, you get the impression it's "gutless" and doesn't have enough power.
The QT II has a clutch pack in the transfer case center differential. If tire slippage is too much from front to rear, that locks up, much like the ABS on a wheel. It's much like ABS for the front to rear axles, rather than each corner. It's pretty unstoppable, and as I found out in Moab Utah, the Jeep will do things beyond your level of comfort. (Including literally drive up a 45 degree ditch bank) It will drive up slick rock that's too steep to walk up, and I kid you not.
Other Jeep exclusives, are things such as the side air bags. Most vehicles, the side bags pop out and then deflate in a crash. The Jeep's ESP system's G-force detectors will keep those bags inflated until you stop moving, because chances are good in an off-road crash, (It is a Jeep, after all) you're going to be rolling down a hill rather than just flop over and stop like most SUV's.
Other little things like the windshield washers: EIGHT nozzles and 2 gallons worth of reservoir. In a Jeep, your mud plastered windshield can get blasted clean, where 98% of other SUV's have a couple of pathetic streams and that's it.
So, even a "soccer mom" version of a Jeep is STILL much more off-road oriented than other SUV's.
