this is curious...'(quote the posted article)'...

"Finally, a full-time 4x4 system like comes on most Grand Cherokees and some
Cherokees and Liberties 'couples' the front and rear axles together, but
they are not mechanically locked together like a part-time 4wd system does.
The coupling can be done via either a differential (just like what is
between the left and right tires) or a fluid (viscous) coupler. The benefit
to a full-time 4wd system is that because the front and rear axles are not
mechanically locked together, the front and rear tires/axles can rotate at
different rpms from each other. This allows a vehicle with a full-time 4wd
system to drive in 4wd "full time" on a paved road without problem since
there is no 'wind-up' problem to harm the drivetrain."...

I was driving in some fresh snow today, packed/loose mixed... and as usual,
I used my "Full Time" 4WD, but I (unusually) was slipping a bit on a very
steep hill and sharp corners and tried "Part Time" and it seemed to work
better. So what gives? I thought "Full Time" was supposed to be better. (I
would never use the "Part Time" on dry pavement)
