It is essential that torque values be maintained to
insure proper operation of the suspension system. The
torque values of the suspension bolts and nuts must be
checked after the initial break-in period of 1,000
miles (1,600 km) and every three months thereafter.
Failure to do so may cause injury to personnel, damage
to equipment and will void the warranty.
If installing new axle, go to alignment procedure. Do
not torque nuts.
Inspect flange on spring seat cap to determine if
socket will fit on bolt. It may be necessary to grind
only enough flange so socket will fit over the head of
the bolt properly.
