          Comments about Rugged Ridge NP231 Slip Yoke Eliminator Kit:

          The bell housing was cast incorrectly. After little to no support from the manufacturer, I had to fix it. I had to grind away material from the inside of the bell housing to get the transfer case to work properly. Apparently I just got a bad one. I was not pleased that I had to do extra work on a brand new part. I'm just glad I checked it out before re-installing in the vehicle.
