The problem
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.
What owners should do
VEHICLES WILL HAVE THE THREE-LEAF SPRING ASSEMBLY REPLACED WITH AN IMPROVED UNIT.
