My son and I have a 79 CJ-5 with a 360, T-18, Amc-20 rear end. We did a spring over axle lift, and now the rear axle raps bad when you punch it. Is there any simple fixes for this, I have tried to get him to put them back on top of the springs but he will not have that, he says that we have gone through to much trouble to turn back now. I'm thinking 4-link or something to that effect. Anyone ever been through this before? Your input would be nice about this problem.
