From my years in the business of steel fabrication I would have to agree 100% with what
is posted on Eaton's site. If it was practical I'm sure they would encourage you to do it.
But the fact remains that the labor to disassemble, clean and prep the leaves, heat treat
and reassemble the stack comes out about the same as making a new spring from scratch.
One thing to remember that even with annealing, re-tempering and drawing back the
molecules in the steel will still show signs of fatigue where some of the bonds have been
torn apart, which means that it is still a candidate for failure long before you would expect
trouble from a new spring. Every used spring that I’ve seen even those with relatively low
mileage shows signs of wear where the ends of the leaves have been working.
I considered re-arching mine when I first brought my truck home because they really were
in great shape and looked fine other than loosing some of their shape. But when I looked
at all the factors and compared the prices decided that new is the only way to go.
