The rear diff is only to be locked when you are stuck (or doing doughnuts
:).  The rear diff is not supposed to be locked for normal driving.  Locking
the rear diff tends to make the car "squirrelly", IME!!

The center is Torsen.  Torsen is a 50/50 split in dry conditions.  When
slippage occurs on the front (or back) wheels, power is automatically
transferred to the wheels that grip.  Up to 2/3 of the power can be routed
front or back.

I have a '89 200 TQ Wagon.  I am fairly displeased with its snow handling as
compared to the older badged 5000QTs that I've driven before and my old '85

My car wants very badly to understeer me right into a ditch when I go into a
corner with any speed.  At first I thought it was because of the
differential unlocking above 10mph so I disconnected the speed sensor to
allow it to remain locked.  That only aggrivated the problem.  So I am
wondering if my problem is from a difference in the center diff.

Can anybody shed light on the center diffs of my car's vintage.  For example
is it open or limited slip?  Can I retrofit a locker easily to the center
diff? Does it bias power to the front greatly?  Is it correct to assume that
this is even my problem??  Is it viscous or torsen?? etc...

Thanks in advance,
