Can someone explain how the vacuum actuated switch in the glovebox works? What does it engage? Does it lock Differentials?

It locks the transfer from full time 4X, to off road 4X. There is a set of clutches in the transfer that allows it to slip some on the pavement, kinda like a limited slip differntial. The switch in the glove compartment, is supposed to do away with the slip and increase off road traction.[addsig]

Thanks Mudderchuck, I wasn't sure and some of my friends came up with some pretty wild ideas on how it works. Now I can explain how it really works. The system does REALLY work, especially when you have it in low lock. I have climbed some grades where Chevy's and Fords can't, they will spin the left front and right rear tire and stop, Ha! I just keep on going. Thanks again. Jeep Rules

Be careful about giving to much gas when your stuck or pulled up against an immovable object. The old quadra-trax have a tendancy to stretch chains inside the transfer, which are expensive. Shifting into low range and using the gears instead of the gas helps make them last longer. Just a little tip from experiance, I´ve changed a few chains.[addsig]
