    Shackles...

    Scott,

    Are those shackles on the rear stock length? They look longer to me. Did you have that same length shackle on the front of the Jeep before you replaced them with the tow shackles? Could be the front is okay but didn't get much raise because of the shackle length from before. That would account for the rear being higher. The Jeep looks like it has pretty good front end lift to me as it sits. Maybe you should shoot some pics to the tech support at 4WD... Just my two, man.

      Blackwater, the rear shackles were on the CJ when I bought it last year. From the center of the frame mount bolt to the center of the spring eye bolt, they measure 5.75". The front stock shackles measured 3" from bolt to bolt. My new tow bar shackles measure 3.5".
      Before I installed the new lift springs, I measured 21" from the ground to the bottom of the frame where the rear bumper mounted. After the lift install I measured 24". I was happy.
      Then I moved to the front. I had a measurement of 23" before the new spring install. After the spring and tow bar shackle install I had 23". NO LIFT!!
      I don't understand why and so far nobody else can explain it either. Just when a project is nearing completion, things like this happen and drive you crazy. Dang Murphy strikes again.

      HELP!! ANYONE?

        Ok, I got it. It is a simple math problem.
        You said
        Before I installed the new lift springs, I measured 21" from the ground to the bottom of the frame where the rear bumper mounted. After the lift install I measured 24". I was happy.
        and
        Then I moved to the front. I had a measurement of 23" before the new spring install. After the spring and tow bar shackle install I had 23". NO LIFT!!
        Now from this I can tell you that your rear springs were worn but your front was not. You also have bigger shackels in the rear so you have just a slight difference in height. You might have had a 2.5 lift on it to begin with but they were just a bit saggy in the rear.
        Look at the picture of your jeep from the side. If you really had the numbers you said you should be able to see the rake on your jeep. As I can barely tell there is a difference in height, I would say you just needed to fix the rear.
        Still have the front springs? They might be good if you bend or break one.

          The picture does not really show how much higher the back is compared to the front. Prior to installing the lift the jeep was level. If the rear springs were worn out and the front springs OK, wouldn't the rear end have been lower? I measured the difference between the front and back using a laser level. The front is now a hair under 3" lower.
          Whatever the cause I need to find a solution.

            Hmmmm, according to the book if you measured from the bottom of the front bumper and the bottom of the rear bumper you should come out with the same height. I have the FSM and the front measurement from the bottom of the frame is just 2 inches different than the measurement from the rear top of the frame. As the frame is approx 2" I figure it should be right.

              Penguin,

              I have an FSM also. What page is that information on?
              I am going to start from scratch and have a friend, who also has an 82 CJ7,
              come over this evening to get a different set of eyes looking at the problem and to make some comparison measurements between the jeeps.
              Thanks for your input and patience.

                It is the one with the frame dimensions.
                But I did notice that these are from the earlier version CJ's before they changed the shock mount. But the other frame dimentions didn't change.

                  I have the page. If the difference between measurements A & F is 2.06",
                  how can the difference between A & B be 4.99"?
                  I measured my frame, it is about 3 3/8" top to bottom in the front and 2 3/4" on the rear frame.
                  With a jeep sitting level, is the frame the same distance off the ground front and rear?

                    Some more math

                    Going by the FSM, when level, the difference in height off the ground between the top of the rear frame and the the bottom of the front frame should be 2.06". The difference on mine is about 4.5", meaning the front is about 2.5" low, exactly what the lift should have given me on the front.

                      Mine is.
                      The front and rear from the bottom of the bumpers is the same measurement.
                      I think your rear might be a bit high. Mine is measured out at 25". I have a bigger than 2.5 lift.
