I lock the center diff when there's anything significantly slippery between
the tires and the road (such as snow, slush, etc.). This keeps the car
from trying to swap ends, especially when changing lanes over that slush
mound in the middle of the highway. The thing to keep in mind is that the
rear end is lighter than the front, so it has a tendency to lose traction
first. The center diff lock can give you a little peace of mind by
ensuring that your tail isn't going to wag into the guy in the next lane.
(I guess it gives him some peace of mind, too!)
>Under what conditions should the rear dif be locked?
When you're *almost* stuck. I only seem to need this when I'm trying to
push through a snowbank at the end of my driveway, or when trying to climb
an unplowed hill at low speeds (again, my driveway). I think it seems to
be better at keeping you from getting stuck than it is a getting you
unstuck, so don't wait until the last second to use it.

It's similar to a front-wheel-drive car in that it tends to understeer;
however, it's not as extreme -- you probably won't understeer yourself into
oblivion as in a FWD car. It's often more like a four-wheel drift.
Backing off the gas generally brings the car back into line (pretty much
immediately); hammering the gas with the center diff unlocked can make the
tail step out (yee-haaaa!!!).
