Forget about the viscous part, it is only in there to help the ABS brake each wheel independantly. Only ABS cruisers get one. If you lift a front wheel in high range you will go nowhere just like if you had a full time with no viscous... there is a way to fix both problems....get a difflock switch that comes in your model but without ABS and install it in the dash...plug the wires in and you can then select locked high range, but the down side (if it can be called that) is you loose ABS whilst it is locked.(good for fast dirt roads)
Put some Castrol VMXM oil in your 5 speed, and it will shift better.
