Welcome
This Workshop Manual is part of a suite of technical manuals
provided for V8 Vantage. Other technical manuals include:
• Parts manual
• OBDII Diagnostic manual
• Man hour schedules
Chapters
Each chapter in this workshop manual is associated with a 4
digit number, i.e. Transmission (07.00). Each chapter is then
further broken into sections, i.e. Automatic Transmission
(07.01).
Chapter Navigation
Example 1:
Older workshop manuals would have Steering and
Suspension together in one chapter. The structure now used
places Steering and Suspension into their own chapters.
When required references are made out to other chapters.
Page Numbering
The page numbering system used within this workshop
manual is as follows:
Systems Classification Coding
Alongside the ‘System’ and ‘Sub system’ section titles appear
codes. For example Exhaust ‘ 09.00’ or Power Steering
‘ 11.02 ’. These codes relate to a Corporate Product Systems
Classification (CPSC) and are designed to segregate the parts
for engineering release and organise a variety of engineering
data.
Special Tools
Where special service tools are required to perform an
operation, the tool number is recorded at the point of use
within the procedure. Where the operation of a special
service tool is complicated or not obvious, refer to Appendix
and Glossary for detailed operation procedures. A pictorial
list of special service tools available for this vehicle can also
be found in Appendix and Glossary.
Location References
References to left, right, front or rear of the vehicle or of a
component are referenced from sitting in the drivers seat
facing forward. Any such refe rences to assemblies removed
from the vehicle are to the normal orientation of the
assembly when installed in the vehicle.
The following Warnings, Cautions and Notes are used within
this Owner’s Guide to call your attention to specific types of
information.

Road Wheels and Tyres (04.04)
Suspension (04.00)
May 2007 Workshop Manual 4-4-3
Maintenance
Factory installed tyres and road wheels are designed to
operate satisfactory when inflated to the recommended
inflation pressures (Refer to ’Inspection and Verification’,
page 4-4-4). The recommended pressures apply to vehicle
loads up to and including the full-rated load capacity.
Correct tyre pressures and driving technique have an
important influence on tyre life. Heavy cornering,
excessively rapid acceleration and unnecessary sharp
braking increase tyre wear.
Replacement tyres should follow the recommended:
The use of any other size or type may seriously affect:
Wheels need to be renewed when:
Safety
Tyre Replacement and Wheel
Interchanging
When replacement of tyres is required it is preferable to
install a complete vehicle set. S hould either the front or rear
tyres only show excessive wear, new tyres must be installed
to replace worn ones. Under no circumstances interchange
tyres from side to side, front to re ar or vice versa as individual
tyre wear produces unique characteristics depending upon
their position. If the position is changed after wear has
occurred, the performance of the tyre will be adversely
affected.
New tyres must be balanced before installing to the vehicle.
•Size
•Speed rating
•Load range
• Radial construction type
•Safety
•Ride
•Handling
• Speedometer and Odometer calibration • Vehicle ground clearance
• Tyre clearance between
body and chassis
• Wheel bearing life
• Brake cooling
• Impact damaged
• Heavily corroded
• Porous • Wheel stud holes or seats
become damaged
• They have excessive radial or lateral runout.
ENSURE THAT TYRES ARE MOUNTED WITH THE
SIDEWALL MARKING ‘OUTSIDE’ SHOWING ON THE
OUTER SIDEWALL FACE.
CORRECT TYRE ROTATIONAL DIRECTION IS CRITICAL.
WA R N I N G
A TYRE AND WHEEL MUST ALWAYS BE CORRECTLY MATCHED. WIDER OR NARROWER TYRES THAN
RECOMMENDED COULD CAUSE DANGER THROUGH
SUDDEN DEFLATION.
WA R N I N G
WHEN CHANGING A WHEEL, MAKE SURE THAT THE VEHICLE CANNOT MOVE. ALWAYS APPLY THE
PARKING BRAKE AND SELE CT THE TRANSMISSION
PARK POSITION (AUTOMATIC TRANSMISSION ONLY).
WA R N I N G
NEVER RUN THE ENGINE WITH ONE WHEEL OFF THE GROUND, FOR EXAMPLE, WHEN CHANGING THE
WHEEL. THE WHEEL RESTING ON THE GROUND MAY CAUSE THE VEHICLE TO MOVE.
WA R N I N G
ALWAYS TIGHTEN THE WHEEL NUTS TO
SPECIFICATION. TOO TIGHT MAY CAUSE DAMAGE,
TOO LOOSE MAY ALLOW TH E WHEEL TO BECOME
DETACHED.
WAR NI NG
DO NOT MIX DIFFERENT TY PES OF TYRES ON THE
SAME VEHICLE. HANDLING MAY BE SERIOUSLY AFFECTED RESULTING IN LOSS OF CONTROL.
WAR NI NG
USE ONLY WHEELS AND WHEEL NUTS SUPPLIED BY
ASTON MARTIN. AFTER MARKET WHEELS OR WHEEL
NUTS MAY NOT INSTALL OR FUNCTION CORRECTLY
AND COULD CAUSE INJURY OR DAMAGE.
Caution
When a new tyre is installe d, always renew the tyre
valve.

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.
Symptoms
SymptomPossible Source(s):Action(s)
Tyres show excess wear on
edge of treads Tyres under-inflated Correct pressure to specification.
Vehicle overloaded Correct as required.
Tyres show excess wear on
