Does anyone have any info of the AWD system Ford used in these? I'd like to
find out if the t-case has a simple differential or if there's some kind of
LS arrangement.

I'd also like opinions on installing a LS in the rear or maybe even both
axles. I'd like to be able to improve traction for loose surfaces, but not
so much that it compromises the on-road AWD benefits in icy conditions.

Any ideas appreciated,
Sean
