Road Wheels and Tyres (04.04)
Suspension (04.00)
May 2007 Workshop Manual 4-4-5
Road Test
A tyre vibration diagnostic proc edure always begins with a road test. The road test and customer interview (if available)
will provide much of the information neede d to find the source of a vibration.
During the road test, drive the vehicle on a road that is smoot h and free of undulations. If vibration is apparent, note and
record the following:
• The speed at which the vibration occurs
• What type of vibration occurs in each speed range
• How the vibration is affected by changes in the following types of vibration-sensitivity:
Torque Sensitive - This means that the condition may be improved or made worse by accelerating, decelerating, coasting,
maintaining a steady vehicle speed or applying engine torque.
Vehicle Speed Sensitive - This means that the vibration always occurs at the same vehicle speed and is not affected by
engine torque, engine speed or the transmission gear selected.
Engine Speed Sensitive - This means that the vibration occurs at varyin g vehicle speeds when a different transmission
gear is selected. It may sometimes be isolated by increasing or decreasing engine speed with the transmission in NEUTRAL
or by stall testing with the transmission in gear. If the condition is engine speed sensitive, the cause is probably not relate d
to the tyres.
If the road test indicates that there is tyre whine, but no sh ake or vibration, the noise originates with the contact between
the tyre and the road surface.
A thumping noise usually means that the tyre has a flat or soft spot making a noise as they slap the roadway. Tyre whine
may be distinguished from axle noise. Tyre whine remains the same over a range of speeds.

SymptomPossible Source(s):Action(s)
SymptomDescription
Age Deterioration Cracking and crazing of the tread and side wall rubber, sometimes accompanied by carcass
deformation. An indication that the tyres have been in service for a very long time.
Neglected Cut Damage through accidental cuts or penetrations will extend in use due to continued flexing and /
or ingress of moisture and road matter.
Impact Fracture Resultant damage from impact fractures is not always visible externally and, therefore, as a safety
precaution the tyre should be removed and examined.
Casing fracture caused by severe localized impact through driving over kerbs, hitting potholes
and / or objects in the road.
A double fracture caused by crushing the side wall of the tyre between an object and the rim
flange.
In both instances, such damage can lead to sudd en and dangerous tyre deflation some time after
the impact occurred.

Fuel Tank and Lines (10.01)
Fuel (10.00)
May 2007 Workshop Manual 10-1-3
Fuel Tank
The fuel tank incorporates a single filler neck and check valve, internal fuel pump, internal fuel filter, a sender unit and an
‘on board refuelling vapour recovery’ system.
Fuel Pumps

)XHO3XPS
The modular fuel pump is immersed in the base of the fuel
tank. The pump can deliver up to 150 litres/hour. The in-
tank fuel line connects to the external line using a quick-fit
connector in the base of the fuel tank. During normal running, pressu
rised fuel from each fuel
pump passes from the tank, through an 3 micron in-tank fuel
filter to one of the two fuel rails on the engine.
Fuel temperature is measured on the primary fuel rail. If fuel
temperature becomes excessive, the fuel pressure is
increased to prevent fuel vaporisation (boiling).
Fuel pressure is measured by sensors on each fuel rail. The
fuel pressure to each rail is regulated as required by
continuously changing the run speed of the associated fuel
pump. Maximum pressure in the system is limited to 5.3 bar
by in-tank pressure regulators.
A constant head of fuel is maintained in the fuel pump
modules to ensure that the pumps cannot run dry in a ‘low
fuel’ situation.
