When replacing leaf springs, the removed u-bolts cannot be reused.

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 its recommended torque level, the u-bolt threads stretch as they mate with the hi-nuts. Although it is not always visible to the naked eye, this damages the threads. Removed the hi-nuts from the u-bolt will cause a cross-threading that will not allow the u-bolt to be adequately re-torqued.
