Because the front drive shaft is offset, the difference in differential ratios
is probably to compensate for some gearing in the transfer case.  The wheels
would then turn at the same speed, front and rear.  This makes the only sense.
Since most people know so little about 4W drive train components, I am willing 
to go to Off-Road Mail column to get the correct answer.  I am curious myself.
By the way the orginal posting was about rotating tires.  Every tire dealer I
have talked to says you must rotate tires on a 4-wheel drive.  Dick Cepek,
(Largest retail off-road tire dealer) recommends rotation every 5K mi., 2.5K if
you have posi.  I typically get 40-45K from my mud tires.  This is excellent
considering the wild tread pattern.

I wish more people would converse on technical issues.  All this debate about
American vs Japanese vs German vs..., can get nowhere!  Each person has his/her 
own opinion!  If more technical subjects were discussed on net.auto people
might learn something to base their opinions on.
