Re: 00 grand cherokee awd problems? need help!
I have never opened my T-case, but it can be split. There is a change that some other internal damage has occured, so only by opening it up you will know more.
Probably easier to get a good junkyard part. You could then even decide to go for a NV242 T-case, which give you full time 4x2, 4x4 or 4x4 Lo. (you have now a NV 247 T-case, which has a progressive coupling inside, which transfers torque to the front wheels when a speed difference exists between front and rear propeller shafts)
