The shackles should be going towards rear on the back of the Jeep. Did you tighten the shackle bolts to torque before the Jeep was back on the ground? If so, that may be your problem. Just loosen the shackle bolts up a bit with the weight of the Jeep on the wheels then re torque. If that does not work, make sure that the little tabs on the leaf springs popped into place for the axle. Good luck.
