      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.

          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 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.
