??
first you should open the diffs, to see if some oil is still in it..

do the wheels spin freely when you turn them on one axle, fr or rr
does the center diff spin if you keep the front wheels on the ground
and spin both rear wheels ??

if you mount new oil, try 3000/3000/5000

you have to check all of them

easy one all your power is going to the rear check your drive line from the centre diff through to your front universals and that includes opening up your front diff, but it sound like your front drive shaft is spinning on the pinion or you have blown the front diff. its no biggy just check it out its a quick fix
cheers

Does it bind or spin smooth just at different rates? Cod have something to do with the cb bearings too. Take the engine out and see how it spins.
