I would jack the car up and put jack stands under the frame. Loosen the u clamps enough that the spring axle combination is loose. Try to determined that the square nut on the bolt holding the spring together is oriented correctly. Then push pull the wheels etc. over to the center and tighten up the u clamps again. You may have to rock the axle some as you are tightening the clamps so the square head goes into its recess.
