The XJ and MJ are/were available with a Dana 44 with the heavy duty towing option or metric ton option. I'm not sure if the XJ always came with a Dana 44 when the towing option was ordered. The axles will interchange between the models and use a 5 on 4.5" wheel bolt pattern. This axle could also be a good low buck swap for a Wrangler YJ, but the sping perches would need to be moved. The shafts are one piece and 30 spline.
