Nice job CRWLR. I tried to explain this to him via email but you did a
much better, and more in depth job of explaining the systems to him.
Probably why he decided to re-ask on the NG. :)

One of the things that might be confusing you is that the switch is
labeled "AXLE LOCK" (lockers), not 'Trac-Lock'. There is no switch for
TRAC-LOCK.

That's because it IS confusing, David! Lockers and trac-lock are
-different- systems. My 99 Sahara had factory trac-lock but no lockers.
You couldn't get factory lockers on a Wrangler until the Rubicon came
out. Remember, that dash switch is for LOCKERS, not TRAC-LOCK.

The Rubicon has the ultimate combination of "drive" wheels (1-4).
Remember, the Jeep really has FOUR axles, one per wheel, that meet at
the differentials. In 2WD, with lockers off, you essentially only have
ONE drive wheel active...the right rear. In this mode, you would get
stuck very quickly offroad, so the Rubi has options. If you put it into
4WD (without the lockers engaged) you have two "drive" wheels. One in
front, one in the rear. If you are in 4WD and you "lock" your rear axle,
you have 3 drive wheels. If you additionally lock your front axle, you
have all 4 wheels powered.

- Lockers physically LOCK both axles (both sides of the differential) so
both wheels spin equally (both become "drive" wheels). You do this with
the switch on the dash. There is a switch position for just the rear, or
the rear and front. DO NOT USE THESE UNLESS YOU ARE OFFROAD!!! Something
WILL break.

- Trac-lock is an automatically engaged clutched system where, when
engaged, it lessens the power to the spinning (stuck) wheel to try and
gain traction by allowing the unstuck wheel to have more power. This is
done automatically and there is no switch for it. It is the hardest to
explain (obviously, for me anyway), but the good part is...you don't
have to use a switch and it's virtually invisible to the driver.

Understand the lockers before you use them. There was a guy (different
forum, I believe) who had his lockers engaged, offroad. He was doing a 3
point turn on the trail and broke something. Now, if you don't need the
lockers, leave them disengaged! Heavy, tight turning is the most
problematic for your locker setup. The guy got his Rubi fixed under
warranty, went out and DID THE SAME THING!! Guess what? It broke again
and he was pissed because the dealer wouldn't fix it.

The Rubicon's rear diff is a limited slip (but not Trac Loc) in it's
unlocked state. Jeep made a good decision to inhibit locker engagement in 2
and 4wd hi, which is where inadvertent (or even intentional) on-road
engagement would be unsafe. One of the Jeep mags had an article on how to
defeat the inhibit circuit so they could be engaged in 2 & 4wd hi range,
probably not a good idea for the general public.

The Rubicon's rear diff is a limited slip (but not Trac Loc) in it's
unlocked state. Jeep made a good decision to inhibit locker engagement in 2
and 4wd hi, which is where inadvertent (or even intentional) on-road
engagement would be unsafe. One of the Jeep mags had an article on how to
defeat the inhibit circuit so they could be engaged in 2 & 4wd hi range,
probably not a good idea for the general public.
