              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

              Comments about Rugged Ridge NP231 Slip Yoke Eliminator Kit:

              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.
