4wd terms
Correct me if I'm wrong but here's how I understand it from reading this
group: Jeep open difs in 4L mean one wheel gets power in the front and
one in the rear, limited slip gives you similar 'one by one' but which
side gets power depends on which wheel(s) are losing traction. rear
locker gives you both sides rear at all times and one front wheel (open
dif in front) possibly with other options like front wheel drive or a
front locker for true 4wd etc.
So with that said, there's also "full time 4wd" and "part time 4wd"
which are counter intuitive (as far as which one is best) and if that's
not enough I've heard the term "independent 4wd". So how do these last
three terms relate to locking difs, limited slip and the stock open
difs? I'm guessing independent is limited slip?
Judging by how easily I lost traction today I'm definitely thinking
about front and rear limited slip; mostly for winter driving.

Re: 4wd terms
Locking diffs simply put power to both wheels on the same axle regardless of
whether you are in full time or part time. In part time it will send power
to both back wheels and then also power to whatever front wheel is slipping
most. In full time, if the rear two tires that are locked start to spin, the
front axle may get no power at all. Full time lets your front and rear axles
turn at different rates. Lockers get you unstuck, or in some cases, more
stuck.

Re: 4wd terms
The term Open Diffs has NOTHING to do with 4LO, or 4HI for that matter.
An open diff sends equal amounts of power to both tires until one of them
begins to slip, then that wheel gets all of the power. The other wheel that
still has traction gets no power, and the vehicle is stuck.
A Limited slip also sends equal power to both wheels until one begins to
slip, then it send the power to the other wheel that still has traction.
A locker sends equal power to both wheels all of the time, regardless of
which wheel has traction ans which is slipping.
Full- and Part Time 4WD has to do with the tcase. The differentials divide
the power from left to right on the axle, the tcase divides the power from
front to rear. The tcase is not able to divide the power in a part time
system, but it can in a full time system. What happens is, when the vehicle
goes around a corner, the front and the rear travel remarkably different
paths, the front is generally a longer path than the rear. Since the time to
trave the paths is essentially the same, then the speeds must be different,
and the tcase must hav ethe ability to privide for these different speeds. A
part time case can not do this, a full time case can. A full time 4WD system
is roughly equivelent to an All Wheel Drive system, but not really.

Incorrect. If only one wheel on either axel is driving the vehicle, then it
would get really squirrelly while you accelerate.
2WD means just that... 2 wheels driving the vehicle. 4WD means that 4 wheels
are driving the vehicle.
It's only when a wheel looses traction that it SEEMS like only one wheel is
driven. Not correct, though.
