Yes, front driveshaft has cv joints. Not front axle. My bad.
I didn't know front axles on Cherokees had cv joints? If they are dana 30s then I'd imagine there should be some way to make it work. I'm not sure there would be any real reason to try though? As far as I know the dana 30 in tj's is a more than capable axle that can run large tires as it sits now. What would be the reason to change to cv joints?
