Since i guess i have a dana 30 in the front, Need to find out if it has a seal just inside the nuckle like the zuks or if it relies on a seal at the carrier bearings in the center like a older GMs.
if you are really curious about what your jeep was built with

provide them with your vin # and ask for the build sheet on your jeep and they
will email it over within 48hrs
