If you guys look at the diagram, the front wheels(front diff) are working first...then the power gets transmitted to the center diff (open)...once that strats to slip it gets transmitted to the Viscous Coupling, and only then... which in turn drives the rear wheels. You'd have to stop the front wheels to see if the VC is working and unless you have an LSD you'd have to apply even pressure to the rear wheels too... it's best to take it out and measure the torque required to spin it. The one I have out of the car is probably in the 120-150ft/lbs ...very stiff. (with nice clear fluid inside) I have two god units if anyone needs one by the way. From what I have read it's fairly easy to take it out if you only remove the transfer case right cover. From looking at mine, they are really, really well made and last a very long time IMHO, doubt yours is bad but you never know until you test it
not calling you out, just saying how i saws it
if im wrong dont beat me too hard.
'when there is a difference in speed from the front(main driven wheel[unless wrong]) it causes the vc to heat up the fluid inside causing the power to be added more and more to the rear until 'locked' or they start to have equal speed thus cooling the fluid inside and losening the tight on the rear.'
"if you guys look at the diagram"
did i miss this? :shock: if so help me.
