I think you pulled out the axle shaft and somehow?? got a CV drive for something other than a 2000 Cherokee Sport. All you need to do is get a replacement U-Joint for the axle shaft and replace it and be done- it is replaceable without removing the axle shaft, and both U-Joints (driver and passenger sides) should be replaced at the same time. A CV drive would be something that is used on the Liberty that has individual control arms and inner and outer CV joints, (Halfshafts) where the Cherokees have a solid front axle and only outer U-joints that are exposed.
