In case the center bolt that holds the spring pack is broken, you may wish to do as my local heavy truck shop does to ensure against spring leaves flying apart as you loosen or cut the old u-bolts. They use sturdy F clamps (C clamps would work) to hold the leaves together, both as they cut the U-bolts and more importantly as they prepare to install a new center bolt.
