Removed U-Bolts should NEVER be placed back onto the vehicle, they should be thrown away.  Suspension U-Bolts are manufactured with a smooth rolled thread, while the mating Hi-Nuts are manufactured with sharp cut threads.  When a U-Bolt is tightened to it's recommended  torque level, the U-Bolt threads stretch as they mate with the Hi-Nuts.  Although, not always visible to the naked eye, this damages the threads.  Removing the Hi-Nuts from the U-Bolt will cause a cross-threading that will not allow the U-Bolt to be adequately re-torqued.  A common practice in most maintenance facilities is to use a impact wrench to tighten U-Bolts.  Consistent, accurate torque is next to impossible to obtain with a impact wrench, and in most cases an over-torqued fastener is the result.  We recommend using a torque wrench when installing U-Bolts.  New U-Bolts should be torqued after 2 weeks of usage.
