are normally stored in cylinders at pressures of up to
138 bar (2000 psi) and great care should be taken in
handling these cylinders to avoid mechanical damage
to them or to the valve gear attached. The contents of
each cylinder should be clearly identified by
appropriate markings.
Cylinders should be stored in well ventilated
enclosures, and protected from ice and snow, or
direct sunlight. Fuel gases, for example acetylene and
propane, should not be stored in close proximity to
oxygen cylinders.
Care should be exercised to prevent leaks from gas
cylinders and lines, and to avoid sources of ignition.

eyes and skin.
Used Engine Oil
Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In
addition, used engine oil contains potentially harmful
contaminants which may cause skin cancer. Adequate
means of skin protection and washing facilities must
be provided.
Do not employ used engine oils as lubricants or for
any application where appreciable skin contact is
likely to occur.
Wash with soap and water to make sure all oil is
removed (skin cleansers and nail brushes will
help). Preparations containing lanoline replace the
natural skin oils which have been removed.
Do not use gasolene (petrol), kerosene (paraffin),
diesel fuel (gas oil), thinners or solvents for
cleaning skin.
If skin disorders develop, obtain medical advice
without delay.
Where practicable, degrease components prior to
handling.
Where there is a risk of eye contact, eye
protection should be worn, for example chemical
goggles or face shields; in addition an eye wash
facility should be provided.

Pressurized Equipment
See High Pressure Air, Lubrication and Oil Test
Equipment.
Solder
Solders are mixtures of metals such that the melting
point of the mixture is below that of the constituent
metals (normally lead and tin). Solder application
does not normally give rise to toxic lead fumes,
provided a gas/air flame is used. Oxy-acetylene
flames should not be used, as they are much hotter
and will cause lead fumes to be produced.
Some fumes may be produced by the application of
any flame to surfaces coated with grease, and
inhalation of these should be avoided.
Removal of excess solder should be undertaken with
care, to make sure that fine lead dust is not produced,
which can give toxic effects if inhaled. Respiratory
protection may be necessary.
Solder spillage and filings should be collected and
removed promptly to prevent general air
contamination by lead.
High standards of personal hygiene are necessary in
order to avoid ingestion of lead or inhalation of solder
dust from clothing.
Make sure there is good ventilation when in use,
avoid breathing fumes, vapours and spray mists and
keep containers tightly sealed. Do not use in confined
spaces.
When spraying materials containing solvents, for
example paints, adhesive, coatings, use extraction
ventilation or personal respiratory protection in the
absence of adequate general ventilation.
Do not apply heat or flame except under specific and
detailed manufacturers instructions.
Sound Insulation
See Fibre Insulation, Foams.
Suspended Loads
CAUTION: Never improvise lifting tackle.
There is always a danger when loads are lifted or
suspended. Never work under an unsupported,
suspended or raised load, for example a suspended
engine.
Always make sure that lifting equipment such as
jacks, hoists, axle stands and slings are adequate and
suitable for the job, in good condition and regularly
maintained.
Transmission Brake Bands
See Asbestos.
Underseal
Solvents
See also Chemical Materials, Fuels (Kerosene), Fire.
For example acetone, white spirit, toluene, xylene,
trichloroethane.
Used in cleaning and dewaxing materials, paints,
plastics, resins and thinners.
Some may be highly flammable or flammable.
Skin contact will degrease the skin and may result in
irritation and dermatitis following repeated or
prolonged contact. Some can be absorbed through
the skin in toxic or harmful quantities.
Splashes in the eye may cause severe irritation and
could lead to loss of vision.
Brief exposure of high concentrations of vapours or
mists will cause eye and throat irritation, drowsiness,
dizziness, headaches and, in the worst
circumstances, unconsciousness.
Repeated or prolonged exposure to excessive but
lower concentrations of vapours or mists, for which
there might not be adequate warning indications, can
cause more serious toxic or harmful effects.
Aspiration into the lungs, for example through
vomiting, is the most serious consequence of
swallowing.
See Corrosion Protection.
Viton
In common with many other manufacturers vehicles,
some components fitted to the Ford range have
O-rings, seals or gaskets which contain a material
known as ‘Viton’.
Viton is a fluoroelastomer, that is a synthetic rubber
type which contains Fluorine. It is commonly used for
O-rings, gaskets and seals of all types. Although Viton
is the most well known fluoroelastomer, there are
others, including Fluorel and Tecmoflon.
When used under design conditions fluoroelastomers
are perfectly safe. If, however, they are exposed to
temperatures in excess of 400°C, the material will not
burn, but will decompose, and one of the products
formed is hydrofluoric acid.
This acid is extremely corrosive and may be absorbed
directly, through contact, into the general body
system.
O-rings, seals or gaskets which have been exposed to
very high temperatures will appear charred or as a
black sticky substance.
DO NOT, under any circumstances touch them or the
attached components.

100-00-12 General Information 100-00-12
DESCRIPTION AND OPERATION (Continued)
Enquiries should be made to determine whether Viton
or any other fluoroelastomer has been used in the
affected O-ring, seal or gasket. If they are of natural
rubber or nitrile there is no hazard. If in doubt, be
cautious as the material may be Viton or any
fluoroelastomer.
If Viton or any other fluoroelastomers have been
used, the affected area should be decontaminated
before the commencement of work.
Disposable heavy duty plastic gloves should be worn
at all times, and the affected area washed down using
wire wool and a limewater (calcium hydroxide)
solution to neutralise the acid before disposing of the
decomposed Viton residue and final cleaning of the
area. After use, the plastic gloves should be discarded
carefully and safely.
Welding
See also Fire, Electric Shock, Gas Cylinders.
Welding processes include Resistance Welding (Spot
Welding), Arc Welding and Gas Welding.
Resistance Welding
This process may cause particles of molten metal to
be emitted at a high velocity, and the eyes and skin
must be protected.
Arc Welding
This process emits a high level of ultra-violet radiation
which may cause arc-eye and skin burns to the
operator and to other persons nearby. Gas-shielded
welding processes are particularly hazardous in this
respect. Personal protection must be worn, and
screens used to shield other people.
CONTACT LENS WEARERS ARE ADVISED TO
REVERT TO ORDINARY SPECTACLES WHEN ARC
WELDING as the arc spectrum is believed to emit
microwaves which dry out the fluid between the lens
and the eye. This may result in blindness when the
lens is removed from the eye.
Metal spatter will also occur, and appropriate eye and
skin protection is necessary.
The heat of the welding arc will produce fumes and
gases from the metals being welded, the rods and
from any applied coatings or contamination on the
surfaces being worked on. These gases and fumes
may be toxic and inhalation of these should be
avoided. The use of extraction ventilation to remove
the fumes from the working area may be necessary
particularly in cases where the general ventilation is
poor, or where considerable welding work is
anticipated. In extreme cases or confined spaces
where adequate ventilation cannot be provided,
air-fed respirators may be necessary.
Gas Welding (and Cutting)
Oxy-acetylene torches may be used for welding and
cutting, and special care must be taken to prevent
leakage of these gases, with consequent risk of fire
and explosion.
The process will produce metal spatter and eye and
skin protection is necessary.
The flame is bright, and eye protection should be
used, but the ultra-violet emission is much less than
that from arc welding, and lighter filters may be used.
The process itself produces few toxic fumes, but such
fumes and gases may be produced from coatings on
the work, particularly during cutting away of damaged
body parts, and inhalation of the fumes should be
avoided.
In brazing, toxic fumes may be produced from the
metals in the brazing rod, and a severe hazard may
arise if brazing rods containing cadmium are used. In
this event particular care must be taken to avoid
inhalation of fumes and expert advice may be
required.
Special precautions must be taken before any welding
or cutting takes place on vessels which have
contained combustible materials, for example boiling
or steaming out of fuel tanks .
Warning Symbols on Vehicles
Decals showing warning symbols will be found on
various vehicle components.
These decals must not be removed. The warnings are
for the attention of owners/operators and persons
carrying out service or repair operations on the
vehicle.
The most commonly found decals are reproduced
below together with an explanation of the warnings.

Standard Workshop Practices
Vehicle in Workshop
When working on a vehicle in the workshop always
make sure that:
the parking brake is applied or the wheels are
securely chocked to prevent the vehicle moving
forwards or backwards.
the key is removed from key operated hood locks
before any work is carried out around the front of
the vehicle.
if the engine is to be run, there is adequate
ventilation, or an extraction hose to remove
exhaust fumes.
there is adequate room to raise the vehicle and
remove the wheels, if necessary.
fender covers are always fitted if any work is to be
carried out in the engine compartment.

CAUTION: When electric arc welding on a
vehicle, always disconnect the generator wiring to
prevent the possibility of a surge of current
causing damage to the internal components of the
generator.
If using welding equipment on the vehicle, a
suitable fire extinguisher is readily available.
Alternative Fuel
WARNING: When servicing the fuel system
always follow the recommended procedures.
Failure to follow these instructions may result in
personal injury.
If the odour of liquified petroleum gas (LPG) or
compressed natural gas (CNG) is present in the air in
the workshop, warn all persons in the area to:
extinguish all flames and lighted tobacco.
shut off electrical and air powered equipment.
evacuate the area.
ventilate the area.
contact fire control authorities.
remove the vehicle to a dedicated, ventilated
area.
Alternative Fuel — Do’s
do work on the vehicle in a designated area that
is well ventilated and its access restricted to
qualified personnel only
install new warning labels to their original
locations
if possible always isolate the alternative fuel tank,
run the vehicle on the alternative fuel until it
automatically switches to its normal fuel prior to
taking the vehicle into the workshop/service area
only use tested and approved components and
pipes when repairing or servicing LPG and CNG
systems
reduced to atmospheric, or less
do not use anything other than the specified leak
detector fluid to trace fuel leaks
Be aware of situations that may cause the LPG or
CNG fuel system to vent off fuel, such as:
extremely hot days
parking by a space heater
hoisting a vehicle up near a ceiling heater
Only personnel fully trained to Ford and local
standards are to work on alternative fuel vehicles.
Towing the Vehicle
WARNING: When the vehicle is being towed
the ignition switch must be in position II (steering
lock released and warning lights illuminated).
Only then will the steering, turn signal lamps,
horn and stop lamps be operational. Failure to
follow these instructions may result in personal
injury.
When a vehicle with automatic transmission is towed,
the gear selector must be in position N (Neutral).
Never tow a vehicle with automatic transmission
faster than 30 mph (50 km/h) or further than 30 miles
(50 km). If it is necessary to tow the vehicle a greater
distance, the drive wheels must be lifted clear off the
ground.
Alternatively the vehicle can be transported on a low
loader or a trailer.
Connecting a Slave Battery Using Jumper
Cables
WARNING: If the slave battery has recently
been charged and is gassing, cover the vent plugs
or covers with a damp cloth to reduce the risk of
explosion should arcing occur when connecting
the jumper cables. Failure to follow these
instructions may result in personal injury.
Alternative Fuel — Do Nots
do not vent off LPG fuel
do not use shop air pressure to force LPG fuel
from the fuel tank
do not use paint drying ovens above 40°C for any
alternative fuel vehicles. LPG and CNG fuel tanks
should be removed from the vehicles prior to
being put into paint drying ovens above 40°C
do not modify the system or install new
components with parts not designed for gas
vehicles
do not evacuate fuel tanks unless there is repair
that requires removed of the fuel tank
G17373 en01/2003 2003.0 BA Falcon
CAUTION: A discharged battery condition
may have been caused by an electrical short
circuit. If this condition exists there will be an
apparently live circuit on the vehicle even when all
normal circuits are switched off. This can cause
arcing when the jumper cables are connected.
CAUTION: While it is not recommended that
the vehicle is jump started, it is recognized that
this may occasionally be the only practical way to
mobilize a vehicle. In such an instance the
discharged battery must be recharged
immediately after jump starting to avoid
permanent damage.
Page 15
100-00-15 General Information 100-00-15
DESCRIPTION AND OPERATION (Continued)
Always make sure that the jumper cables are
adequate for the task. Heavy duty cables must be
used.
Always make sure that the slave battery is of the
same voltage as the vehicle battery. The batteries
must be connected in parallel.
Always make sure that switchable electric circuits
are switched off before connecting jumper cables.
This reduces the risk of arcing occurring when the
final connection is made.
WARNING: Make sure that the ends of the
jumper cables do not touch each other or ground
against the vehicle body at any time while the
cables are attached to the battery. A fully charged
battery, if shorted through jumper cables, can
discharge at a rate well above 1000 amps causing
violent arcing and very rapid heating of the
jumper cables and terminals, and can even cause
the battery to explode. Failure to follow these
instructions may result in personal injury.
Always connect the jumper cables in the following
sequence:
slave battery positive first then vehicle battery
positive
slave battery negative next and then vehicle
ground at least 12 inches (300 mm) from the
battery terminal, for example engine lifting eye
Always reduce the engine speed to idle before
disconnecting the jumper cables.
Before removing the jumper cables from the vehicle
that had the discharged battery, switch on the heater
blower (high) or the heated rear window, to reduce the
voltage peak when the cables are removed.
Always disconnect the jumper cables in the reverse
order to the connecting sequence and do not short
the ends of the cables.
Do not rely on the generator to restore a discharged
battery. For a generator to recharge a battery, it would
take in excess of eight hours continuous driving with
no additional loads placed on the battery.
Component Cleaning
To prevent ingress of dirt, accumulations of loose dirt
and greasy deposits should be removed before
disconnecting or dismantling components or
assemblies.
Components should be thoroughly cleaned before
inspection prior to reassembly.
Cleaning Methods:
dry cleaning
removal of loose dirt with soft or cable brushes
scraping dirt off with a piece of metal or wood
wiping off with a rag
CAUTION: Compressed air is sometimes
‘wet’ so use with caution, especially on hydraulic
systems.
blowing dirt off with compressed air. (Eye
protection must be worn when using this method)
removal of dry dust using vacuum equipment.
This method should always be used to remove
friction lining material dust (asbestos particles)
steam cleaning
WARNING: Most solvents require careful
handling and some are harmful. Refer to Health
and Safety Precautions and to the manufacturers
literature for safety precautions. Failure to follow
these instructions may result in personal injury.
Various solvents are available which are suitable for
component cleaning. Some components such as
brake hydraulic parts and electrical assemblies should
be cleaned only with recommended solvents — refer
to Solvents, Sealers and Adhesives or to the section
of the manual relevant to the component.
Calibration of Essential Measuring
Equipment
WARNING: Failure to follow these
instructions may result in personal injury or
damage to components.
It is of fundamental importance that certain essential
equipment, for example torque wrenches,
multimeters, exhaust gas analysers or rolling roads,
are regularly calibrated in accordance with the
manufacturers instructions.

WARNING: If the brake system hydraulic fluid
level is low, pedal travel is excessive or a
hydraulic leak is found, do not attempt to road
test the vehicle until the reason for the low fluid
level, excessive pedal travel or hydraulic leak is
found and rectified.
It is suggested that pre-test checks, and functional
tests of those systems/circuits which affect the safe
and legal operations of the vehicle, such as brakes,
lights and steering, should always be carried out
before the road or roller test.

Brake Testing
WARNING: When brake testing, avoid
breathing the smoke or fumes from hot brakes,
this may contain asbestos dust which is
hazardous to health, see Health and Safety
Precautions.
Avoid brake testing on busy roads where it can cause
inconvenience or danger to other road users.
CAUTION: Brake testing which includes
heavy brake applications should not be carried
out with new brake pads/discs or linings/drums
until the components have bedded-in. New brake
friction components will not reach full efficiency
until the bedding-in process is complete.
Test the brakes at several speeds within the normal
operating range using both light and heavy pedal
pressure. Note any tendency to snatch, pull or drag,
and any undue delay in application or release.
Allow the vehicle to coast and note any tendency to
pull to one side, or evidence that the brakes are
binding.
After stopping the vehicle (not immediately after a
period of heavy braking), carefully check the brake
temperature. A disc which feels hot, or appreciably
hotter than the others, indicates that the brake is
binding.
After completion of the test, check for:
Oil, coolant, hydraulic, air and fuel leaks.
Abnormal temperature of any moving components
or assemblies, e.g. wheel hubs, transmission,
axle etc., which might indicate overtightness or
lack of lubrication.
The vehicle identification number (VIN) is a seventeen-digit combination of letters and numbers. The VIN is

DIAGNOSIS AND TESTING
Noise, Vibration and Harshness (NVH) ................................................................................100-04-7
Noise is any undesirable sound, usually unpleasant in
nature. Vibration is any motion, shaking or trembling,
that can be felt or seen when an object moves back
and forth or up and down. Harshness is a ride quality
issue where the vehicle’s response to the road
transmits sharply to the customer. Harshness
normally describes a firmer than usual response from
the suspension system. Noise, vibration and
harshness (NVH) is a term used to describe these
conditions, which result in varying degrees of
dissatisfaction. Although, a certain level of NVH
caused by road and environmental conditions is
normal. This section is designed to aid in the
diagnosis, testing and repair of NVH concerns.
Acceptable Noise, Vibration and
Harshness
All internal combustion engines and drivelines
produce some noise and vibration; operating in a real
world environment adds noise that is not subject to
control. Vibration isolators, mufflers and dampers
reduce these to acceptable levels. A driver who is
unfamiliar with a vehicle can think that some sounds
are abnormal when actually the sounds are normal for
the vehicle type. For example, Traction-Lok®
differentials produce a slight noise on slow turns after
extended highway driving. This is acceptable and has
no detrimental effect on the locking axle function. As a
technician, it is very important to be familiar with
vehicle features and know how they relate to NVH
concerns and their diagnosis. If, for example, the
vehicle has automatic overdrive it is important to test
drive the vehicle both in and out of overdrive mode.
within an acceptable range.
Glossary of Terms
Acceleration-Light
An increase in speed at less than half throttle.
Acceleration-Medium
An increase in speed at half to nearly full throttle,
such as 0-97 km/h (0-60 mph) in approximately 30
seconds.
Acceleration-Heavy
An increase in speed at one-half to full throttle, such
as 0-97 km/h (0-60 mph) in approximately 20
seconds.
Ambient Temperature
The surrounding or prevailing temperature.
Amplitude
The quantity or amount of energy produced by a
vibrating component (G force). An extreme vibration

DIAGNOSIS AND TESTING
Noise, Vibration and Harshness (NVH)
To assist the service advisor and the technician, a
Write-up Job Aid and an NVH Diagnostic Guide are
included with this material. The Write-up Job Aid
serves as a place to record all important symptom
information. NHV Diagnostic Guide serves as a place
to record information reported on the Write-up Job Aid
as well as data from the testing to be carried out.
To begin a successful diagnosis, fill out the NVH
Diagnostic Guide, record the reported findings, then
proceed to each of the numbered process steps to
complete the diagnosis.

DIAGNOSIS AND TESTING (Continued)
1: Customer Interview
The diagnostic process starts with the customer
interview. The service advisor must obtain as much
information as possible about the concern and take a
test drive with the customer. There are many ways a
customer will describe NVH concerns and this will
help minimize confusion arising from descriptive
language differences. It is important that the concern
is correctly interpreted and the customer descriptions
are recorded. During the interview, ask the following
questions:
When was the concern first noticed?
Did the concern appear suddenly or gradually?
Did any abnormal occurrence coincide with orsensitive to torque. A drive engine run-up (DERU) or a
proceed its appearance?neutral engine run-up (NERU) test identifies noises
Use the information gained from the customer to
accurately begin the diagnostic process.
2: Pre-Drive Check
It is important to do a pre-drive check before road
testing the vehicle. A pre-drive check verifies that the
vehicle is relatively safe to drive and eliminates any
obvious faults on the vehicle.
The pre-drive check consists of a brief visual
inspection. During this brief inspection, take note of
anything that will compromise safety during the road
test and make those repairs or adjustments before
taking the vehicle on the road.The following is a brief overview of each test in the
3: Preparing for the Road Test
Observe the following when preparing for the road
test:
Review the information recorded on the NVH
Diagnostic Guide. It is important to know the
specific concern the customer has with the
vehicle.
Do not be misled by the reported location of the
noise or vibration. The cause can actually be
some distance away, transferred from another
part of the vehicle.
Remember that the vibrating source component
(originator) may only generate a small vibration.
This small vibration can in turn cause a largerThe Downshift Speed Test helps to determine if

testing route is an open, low-traffic area where it
is possible to operate the vehicle at the speed in
which the condition occurs.
If possible, lower the radio antenna in order to
minimize turbulence. Identify anything that could
potentially make noise or be a source of wind
noise. Inspect the vehicle for add-on items that
create vibration/noise. Turn off the radio and the
heating and cooling system blower.
The engine speed is an important factor in arriving
at a final conclusion. Therefore, connect an
accurate tachometer to the engine, even if the
vehicle has a tachometer. Use a tachometer that
has clearly defined increments of less than 50
rpm. This ensures an exact engine speed reading.
4: Verify the Customer Concern
Verify the customer concern by carrying out a road
test, an engine run-up test, or both.
The decision to carry out a road test, an engine
run-up test, or both depends on the type of NVH
concern. A road test may be necessary if the
symptom relates to the suspension system or is
and vibrations relating to engine and drivetrain rpm.
Remember, a condition will not always be identifiable
by carrying out these tests, however, they will
eliminate many possibilities if carried out correctly.

order in which it appears. A review of this information
helps to quickly identify the most appropriate process
necessary to make a successful diagnosis. After
reviewing this information, select and carry out the
appropriate test(s), proceeding to the next step of this
process.
It may be necessary to have the customer ride
The Slow Acceleration Test is normally the first
test to carry out when identifying an NVH concern,
especially when a road test with the customer is
not possible.
The Heavy Acceleration Test helps to determine if
the concern is torque-related.
The Neutral Coast Down Speed Test helps to
determine if the concern is vehicle speed-related.
The Steering Input Test helps to determine how

100-04-11 Noise, Vibration and Harshness 100-04-11
DIAGNOSIS AND TESTING (Continued)
tests help to determine if the concern is engine
speed-related.
The Neutral Run-up Test is used as a follow-up
test to the Downshift Speed Test when the
concern occurs at idle.
The Engine Load Test helps to identify
vibration/noise sensitive to engine load or torque.
It also helps to reproduce engine speed-related
concerns that cannot be duplicated when carrying
out the Neutral Run-up Test or the Neutral Coast
Down Test.
The Engine Accessory Test helps to locate faulty
belts and accessories that cause engine
speed-related concerns.
The Vehicle Cold Soak Procedure helps to
identify concerns occurring during initial start-up
and when an extended time lapse occurs between
vehicle usage.
Slow Acceleration Test
To carry out this test, proceed as follows:
Slowly accelerate to the speed where the reported
concern occurs. Note the vehicle speed, the
engine rpm and, if possible, determine the
vibration frequency.
Attempt to identify from what part of the vehicle
the concern is coming.
Attempt to identify the source of the concern.
Proceed as necessary.
Heavy Acceleration Test
To carry out this test, proceed as follows:
Accelerate hard from 0-64 km/h (0-40 mph).
Decelerate in a lower gear.
The concern is torque-related if duplicated while
carrying out this test.
Proceed as necessary.
Neutral Coast Down Speed Test
Downshift Speed Test
To carry out this test, proceed as follows:
Shift into a lower gear than the gear used when
carrying out the Slow Acceleration Test.
Drive at the engine rpm where the concern
occurs.
The concern is engine speed related if duplicated
while carrying out this test. This eliminates the
tyres, wheels, brakes and the suspension
components as sources.
If necessary, repeat this test using other gears
and NEUTRAL to verify the results.
Proceed as necessary.
Steering Input Test
To carry out this test, proceed as follows:
Drive at the speed where the concern occurs,
while making sweeping turns in both directions.
If the concern goes away or gets worse, the
wheel bearings, hubs, U-joints (contained in the
axles of 4WD applications), and tyre tread wear
are all possible sources.
Proceed as necessary.
Brake Test
To carry out this test, proceed as follows:
Warm the brakes by slowing the vehicle a few
times from 80–32 km/h (50–20 mph) using light
braking applications. At highway speeds of 89–97
km/h (50–60 mph), apply the brake using a light
pedal force.
Accelerate to 89–97 km/h (55–60 mph).
Lightly apply the brakes and slow the vehicle to
30 km/h (20 mph).
A brake vibration noise can be felt in the steering
wheel, seat or brake pedal. A brake noise can be
heard upon brake application and diminish when
the brake is release.
To carry out this test, proceed as follows:
Drive at a higher rate of speed than where the
concern occurred when carrying out the Slow
Acceleration Test.
Place the transmission in NEUTRAL and coast
down past the speed where the concern occurs.
The concern is vehicle speed-related if duplicated
while carrying out this test. This eliminates the
engine and the torque converter as sources.
If the concern was not duplicated while carrying
out this test, carry out the Downshift Speed Test
to verify if the concern is engine speed-related.
Proceed as necessary.
G72679 en01/2003 2003.0 BA Falcon
Road Test Over Bumps
To carry out this test, proceed as follows:
Drive the vehicle over a bump or rough surface
one wheel at a time to determine if the noise is
coming from the front or the back and the left or
the right side of the vehicle.
Proceed as necessary.
Neutral Engine Run-up (NERU) Test
To carry out this test, proceed as follows:

Drive Engine Run-Up (DERU) Load Test
To carry out this test, proceed as follows:
WARNING: Block the front and rear
wheels, and apply the parking brake and the
service brake, or injury to personnel can
result.
CAUTION: Do not carry out the Engine
Load Test for more than five seconds or
damage to the transmission or transaxle can
result.
Block the front and rear wheels.
Apply the parking brake and the service brake.
Install a tachometer.
Shift the transmission into DRIVE, and increase
and decrease the engine rpm between an idle to
approximately 2,000 rpm. Note the engine rpm
and, if possible, determine the vibration
frequency.
Repeat the test in REVERSE.
If the vibration or noise is duplicated when
carrying out this test, inspect the engine and
transmission or transaxle mounts.
If the concern is definitely engine speed-related,
carry out the Engine Accessory Test to narrow
down the source.
Proceed as necessary.
Engine Accessory Test
To carry out this test, proceed as follows:
WARNING: Block the front and rear

NOTE:
usefulness of this test. In these cases, use a
vibration analyzer, such as the EVA, to pinpoint
accessory vibrations. An electronic listening
device, such as an EngineEAR, will also help to
identify noises from specific accessories.
Remove the accessory drive belts.
Increase the engine rpm to where the concern
occurs.
A serpentine drive belt decreases the
sources.
carrying out this test, install each accessory belt,
one at a time, to locate the source.
Vehicle Cold Soak Procedure
To carry out this procedure, proceed as follows:
Test preparations include matching customer
conditions (if known). If not known, document the
test conditions: gear selection and engine rpm.
Monitor the vibration/noise duration with a watch
for up to three minutes.
Park the vehicle where testing will occur. The
vehicle must remain at or below the concern
temperature (if known) for 6-8 hours.
Before starting the engine, conduct a visual
inspection under the hood.
Turn the key on, but do not start the engine.
Listen for the fuel pump, anti-lock brake system
(ABS) and air suspension system noises.
Start the engine.
CAUTION: Never probe moving parts.
Isolate the vibration/noise by carefully listening.
Move around the vehicle while listening to find the
general location of the vibration/noise. Then,
search for a more precise location by using a
stethoscope or EngineEAR.
Refer to Idle Noise/Vibration in the Symptom
Chart to assist with the diagnosis.
6: Check OASIS/TSBs/Repair History
After verifying the customer concern, check for OASIS
reports, TSBs and the vehicle repair history for related
concerns. If information relating to a diagnosis/repair
is found, carry out the procedure(s) specified in that
information.
If no information is available from these sources, carry
out the vehicle preliminary inspection to eliminate any
obvious faults.
7: Diagnostic Procedure
Qualifying the concern by the particular sensation
present can help narrow down the concern. Always
use the “symptom” to “system” to “component” to
“cause” diagnosis technique. This diagnostic method
divides the problem into related areas to correct the
customer concern.
Verify the “symptom”.
Determine which “system(s)” can cause the
“symptom”.
If a vibration concern is vehicle speed related,
the tyre and wheel rpm/frequency or
driveshaft frequency should be calculated.

DIAGNOSIS AND TESTING (Continued)
Wheel and tyre NVH concerns are directly related to
vehicle speed and are not generally affected by
acceleration, coasting or decelerating. Also,
out-of-balance wheel and tyres can vibrate at more
than one speed. A vibration that is affected by the
engine rpm, or is eliminated by placing the
transmission in NEUTRAL is not related to the tyre
and wheel. As a general rule, tyre and wheel
vibrations felt in the steering wheel are related to the
front tyre and wheel assemblies. Vibrations felt in the
seat or floor are related to the rear tyre and wheel
assemblies. This can initially isolate a concern to the
front or rear.
Careful attention must be paid to the tyre and wheels.
There are several symptoms that can be caused by
damaged or worn tyre and wheels. Carry out a careful
visual inspection of the tyres and wheel assemblies.
Spin the tyres slowly and watch for signs of lateral or
radial runout. Refer to the tyre wear chart to
determine the tyre wear conditions and actions.
For a vibration concern, use the vehicle speed to
determine tyre/wheel frequency and rpm. Calculate
tyre and wheel rpm and frequency by carrying out and
following:
Measure the diameter of the tyre.
Record the speed at which the vibration occurs.
Obtain the corresponding tyre and wheel rpm and
frequency from the Tyre Speed and Frequency
Chart.
If the vehicle speed is not listed, divide the
vehicle speed at which the vibration occurs by
16 (km/h (10 mph). Multiply that number by
16 km/h (10 mph) tyre rpm listed for that tyre
diameter in the chart. Then divide that number
by 60. For example: a 40 mph vibration with
835 mm (33 in) tyres. 40 ÷10 = 4. Multiply 4
by 105 = 420 rpm. Divide 420 rpm by 60
seconds = 7 Hz at 40mph.

Front Wheel Alignment
Suggested method and sequence for checking
steering wander or drift
1. Check and adjust tyre pressures to specification.Toe settings are provided in degrees.
Make sure the vehicle is loaded evenly so ride
heights are relatively even side to side.
2. Check all wheel bearings, steering mechanisms
and suspension joints are to specification. Adjust,
repair or replace as required.
3. Check tyres for uneven wear patterns especially
the inner edges compared to the outer edges.
Rotate tyres front to rear if required.
4. Road test vehicle on a level road surface and
note direction and extent of steering pull or drift.
Ensure prevailing crosswinds are not a factor.
5. If pull of drift is confirmed check the wheel
alignment and confirm that the vehicle is within
specification.
Wheel Alignment Equipment/Maintenance
It is extremely important the wheel alignment
equipment used is periodically checked and
recalibrated to ensure vehicle readings are both
accurate and repeatable. Please consult your
equipment supplier for advice as to how and when the
periodic checking and recalibration should occur.
Regular checking and calibration of wheel alignment
equipment is essential with the current generation of
wheel alignment machines.

DESCRIPTION AND OPERATION
Front Suspension
Suspension
The suspension is so designed that it allows an6Shock Absorber Frt
individual wheel to compensate for changes in the
road’s surface level without considerably affecting the
opposite wheel. Each wheel is independently
connected to the frame and body by a spindle, ball
joint assemblies, and upper and lower control arms.
The control arms are specifically designed and
positioned to allow the steering spindle to move in a
prescribed three dimensional arc. The front wheels
are held in proper relationship to each other by two tie
rods that are connected to the steering rack and to
the spindles.
Coil chassis springs are mounted between the spring
housings on the front end sheet metal and the spring
seats that are integral with the shock absorber body.
Ride control is provided by double, direct acting shock
absorbers mounted inside the coil springs and
attached to the lower control arms by bolts. The upper
portion of each shock absorber extends through the
dual path shear mount and is secured with two
grommets, two grommet retainers, and a nut.
Side roll of the suspension is controlled by a spring
steel stabilizer bar. It is mounted in rubber bushings
held to the frame side rails by brackets.
The ends of the stabilizer are connected to the lower
control arms. Rubber grommets at these connections
provide flexibility and ride features.
The upper control arm is attached to the body through
isolating rubber bushings connected to brackets that
are bolted to the body.
The upper ball joint is a press fit into the upper control
arm, and the stud is fitted into the upper control end of
the spindle forging. A nylok nut and bolt clamps the
spindle to the ball joint.
The lower ball joint is a press fit into the lower arm,
and secures to the lower end of the spindle forging by
a tapered stud and nylok nut.
The inner ends of the lower control arms have
pressed in bushings and are attached to the cross
members by a single bolt through each bushing.
The suspension mounting points are all rubber
insulated to minimise the transmission of road noise
and vibration to the vehicle body.
Compliance in the lower arm bushes permits the
wheel a small amount of fore and aft movement and
so reduce the shock loading on the steering linkage
when the wheel hits a sudden irregularity in the road
surface.
