most likely the rear. but it may be electronic, not mechanical. the nissan pathfinder/infiniti qx4 is not a serious off-roader like a land rover or g-wagon. it is set-up for winter and dirt roads. i am assuming your infiniti is a US model.
you may want to see if you can find a nissan/infiniti forum similiar to this mercedes forum. it would be much more informative there than here.

and...since i am feeling nice and rather bored tonite. i will search a little for you.[:)]

from nissan.com:

All-Mode 4WD®
The LE 4x4 All-Mode 4WD® system is so advanced, we applied for over 560 patents in the creation of it. This is how it works: Set the dash-mounted switch to AUTO and the system takes over, automatically and instantaneously adjusting the front-to-rear torque according to the changing traction. So you get optimal 2WD fuel economy when the going's easy, and optimal 4WD traction when it's not. The AUTO-mode torque control is also linked to the all-terrain ABS, enhancing braking effectiveness and vehicle stability when ABS is applied.

Vehicle Dynamic Control
Vehicle Dynamic Control (VDC) enhances performance in emergency maneuvers, helping to improve control even on slippery surfaces by managing engine power and modifying brake pressure for each wheel individually. It also helps correct over- or understeer caused by the driver, so the vehicle can stay on its intended course.* View
*VDC is designed to help improve driving stability, but does not prevent accidents due to abrupt steering or by carelessness or dangerous driving techniques. Always drive safely.

Traction Control System
Traction Control System (TCS) helps to limit rear-wheel spin during acceleration to improve driver control in both wet and dry conditions by cutting fuel to one or more cylinders, or applying the brakes when needed.

forums from google.com:



and here is a little article about the 1998 QX4:

you've got a combo pack...

What does that mean.

Some history first. In a full time 4wd car you have 3 differentials. Front, center, and rear. Each one allows for variable rates of rotation. For that reason, only on tire on the car actually has to rotate. For example, if you lift it off the ground and have one guy hold each tire, only the weakest guy looses the his tire will send him flying.

You dono't have a center locking diff. You have a locking transfer case. so your car is usually 2wd and then you can lock the center. Now one wheel forward and one wheel backward has to rotate. The weakest guy at the front tires as well as the weakest guy at the rear tires looses.

THe one other thing you car may have... i haven't read up on it... is brake assisted 4 wheel drive... this is electoronics tied into the anti-lock system which will apply brakes to any tire sliding too fast. The effect is that even if you only have traction to one tire, it'll apply the brakes to the other three tires and still get power. It's a neat way of mimicing multiple differential lock.
