   A spring leaf may fracture through the center hole section. This occurs due to loosening of the spring-to-axle mounting attachment following extreme flexing of the spring leaves. This kind of fracture makes the remaining two leaves vulnerable to progressive fracture.

   Remedy: Vehicles will have the three-leaf spring assembly replaced with an improved unit.
