CHASSIS MAINTENANCE
Springs
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.
Inspect the chassis for broken springs, shocks, loose or broken axle U-bolts. If
any of these are found, contact your local Volvo dealer. The U-bolt nuts must
be retightened to the proper torque specifications after the first 24 000 km
(15,000 miles).
