A friend and I were replacing the axle u-joint on my 2000 Wrangler and the part I got I told the guy working there the year and the model of my Jeep. To make a long story short, we get the old one out and the one I bought is too big. We took the driveshaft out and I figured while the driveshaft is out I might as well think about replacing those also. My question is, is the axle and driveshaft U-joints the same size? I dont want to get the wrong size again and I figure you guys would know better than the guys at the auto parts shop. So if you could answer this for me and save me one more trip to the auto parts shop I would greatly appreciate it.
