Steered rear axle
The truck may have a hydraulically steered pusher
axle or a hydraulically steered trailing wheel axle,
controlled electronically.
If a fault occurs in the electro-hydraulic system the
axle will be completely unsteered and it will not be
possible to reverse the truck unless the axle is raised.
Remember that a fault in the system also effect the
driving characteristics when driving straight forwards.
Small simple faults can be corrected by stopping the
truck, turning the ignition key to 0, waiting a short
while and then restarting the engine.
Warning!
Do not try to fix any faults on the
steering of the pusher axle or
trailing wheel axle yourself but
contact a Volvo workshop.
Warning!
In case of any fault with the
steering for the pusher axle or the
tag axle, contact your closest
Volvo workshop. Reversing must
be avoided as this can damage the
truck. There is a great risk that
components e.g. hubs, bearings,
wheels can suffer permanent
damage and must be replaced.
