Steering
System overview
The steering system now has a number of new
components that have been replaced and
modified due to adaptation to the new V6 diesel
engine and to lower the gross weight of the
chassis. All 9-5 models benefit from these
changes.
Steering swivel member
The steering swivel member is cast in aluminum
(die casting) with integrated hub. The front wheel
bearing is a complete hub that is bolted directly to
the steering swivel member with three bolts.
Replacement hubs are fitted complete with three
bolts. This arrangement has reduced the weight
of each steering swivel member by 1.5kg (3.3lb.)
A number of other adaptations have also been
made. These changes are designed to help the
overall handling of the vehicle.
Steering column
The steering column assembly has been adapted
for the new steering angle sensor, which is
located on the steering column between the
steering wheel and the intermediate shaft with
the universal joint. It has also been given a new
arrangement for steering wheel adjustment.
Miscellaneous
Because the new V6 diesel engine has a new
power steering pump, the front and rear pressure
lines are new and have been replaced for space
reasons in the engine compartment. A new,
longer, cooling coil has been introduced on the
front pressure line to provide improved cooling.
There is an additional cooling fin on the B235R
and B308E. The steering gear now has narrower
tolerances to provide the best possible
characteristics for all models. The control valve
has a new specification and is not backward
compatible.
