              I had to replace clutch so I went ahead and did a slip yok eliminator kit and drive shaft well worth every penny. I can really see a difference

              My jeep was stuck in 4 wheel drive, turns out it had to be taken back off and shaved down to fit correctly. I was told this isn't the first one to have this problem either.

                  Hello Ethan
                  The 1330 yoke is available in 32 spline but is not for a cv drive shaft. The cv shafts are done in 1310 only.

                  Hi Brandon
                  If you are looking for a short shaft kit for your 1999 Jeep Cherokee first make sure that you have the NP231 and not the Np 242 Transfer case. As far as the rear driveshaft we would need a length required after conversion. and we fan check with terraflex for a unit http://jo.my/5keyyv Thank You

                  JW yes you will require a new rear drive shaft if you install the Slip Yoke Eliminator Kit on your 2001 Jeep XJ Cherokee. You will be converting from the factory style Slip yoke to a solid mounted double u-Joint or CV style at the top. The shaft will also have to be longer and we will need to know the amount of lift if any before i can recommend a drive shaft part number for you. Thank you for the opportunity to assist you.

                  If you have the NP231 transfer case the Rugged Ridge NP231 Slip Yoke will work for your application.
