Chassis Maintenance

Springs
NOTE! This work is best performed by a
Volvo Truck dealer or other service outlet
having the proper equipment.
The spring package is fastened to the axle
beam with U-bolts. It is important that the
U-bolt nuts are properly tightened. The nuts
may loosen up with time. Severe roads and
service will loosen them faster. Loose U-
bolts can cause springs to break, axle
misalignment, hard steering and abnormal
tire wear.
Do not operate the vehicle if the U-bolts
are loose. If the U-bolts are loose, the
axle is not properly secured to the sus-
pension. This could cause loss of control
of the vehicle leading to an accident re-
sulting in personal injury or death.
The U-bolt nuts need to be retightened to
the proper torque, both on front and rear
axles, at 15,000 miles (24,000 km). Torque
for the front axle is 310 ft-lb (420 Nm) and
for the rear axle it is 370 ft-lb (500 Nm).
