    How do you identify wide track rear ends?

    LLLUUUKKKEEEE...........


    Use the search.............

    I don't know the dimensions off the top of my head, but the search will find it. What year are you talking about. 81 and older are narrow track if they are original. Your 84 should be wide track, again unless it was swapped out. Can't imagine many people would change a wide to a narrow.

      Try this:


      AMC 20/CJ Narrow Track , Wheel to Wheel 50.5" Years '76-'81
      AMC 20/CJ Wide Track, Wheel to Wheel 54.5" Years '82-'86

      It came from Here:

          You can't go by wheel to wheel due to different rim backspacing. You need to measure from wheel mounting surface to wheel mounting surface (wms).

          Edit: Wide track axles are 56" wms to wms for the front and 54.5 for the rear.

            Ah, I see.

            Well I was having a bit of confusion. The guy I bought the '82 Scambler(6cyl auto trans doaner) was going on about how these were wide track axles. After measuring my 84 CJ7 i was a bit torqed. But after playing with the CJ8 I found I had a "track lock" rear end, so I was happy again.

            So i still wanted to understand where the wide track fell in place.

            He was right, I was un-informed

            Thanks for the help, and the links.

            Transplant went smooth, I drove it before thanksgiving. Only problem was it was real "doggy". Killed it 3 or 4 times trying to take off at stop signs.

            Never realized there was so much difference in gearing.

            Next step : swap rear ends
