DESCRIPTION AND OPERATION
Always disconnect the jumper cables in the reverse
order to the connecting sequence and do not short
i 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 the 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.
A WARN1NG:Wear eye protection when
cleaning vehicle components with
compressed air, a steam cleaner or a
power washer. Failure to follow this
instruction may result in personal injury.
CAUTIONS:
A Compressed air is sometimes 'wet' so use
with caution, especially on hydraulic
systems.
A To prevent damage to the electrical
connectors in the engine compartment, do
not use a steam cleaner or a power washer
to clean the engine compartment.
- Blowing dirt off with compressed air.
- Removal of dry dust using vacuum equipment.
This method must always be used to remove
friction lining material dust (asbestos particles).
- Steam cleaning.
A WARN1NG:Most solvents require careful
handling and some are harmful. Refer to
Health and Safety Precautions and to the
manufacturers literature for the relevant
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.

Inspection and Verification
1. Verify the customer concern. Identify the Condition
2. Visually inspect for obvious signs of mechanical NVH usually occur in four areas:
or electrical damage.
tires
3. If an obvious cause for an observed or reported
concern is found, correct the cause (if possible) engine accessories
before proceeding to the next step.
suspension
4. If the concern is not visually evident, verify the
symptom and REFER to the Symptom Chart.
How to Use this Diagnostic Procedure
Section
Noise, vibration and harshness (NVH) concerns
have become more important as
vehjcles have
become more sensitive to these vibrations. This
section is designed to aid in identifying these
concerns.
The section provides diagnostic procedures based on symptom. If the condition occurs at
high speed, for instance, the most likely place
to start is under Shake and Vibration While
Driving.
The road test procedure will tell how to sort the
conditions into categories and how to tell a
vibration from a shake.
A series of Road Test Quick Checks are
provided to make sure that a cause is either
pinpointed or eliminated.
Name the condition, proceed to the appropriate
section and locate the correct diagnosis. When
the condition is identified, the job is partly done.
Follow the diagnostic procedure as outlined.
Quick Checks are described within the step,
while more involved tests and adjustments are
outlined in General Procedures.
Always follow each step exactly and make notes
to recall important findings later.
driveline
It is important, therefore, that an NVH concern be
isolated into its specific
area(s) as soon as
possible. The easiest and quickest way to do this
is to carry out the Road Test as outlined. To assist
in the diagnosis and testing
procedure(s), use a
suitable approved NVH diagnosis tester.
Noise Diagnostic Procedure
Non-Axle Noise
The five most common sources of non-axle noise
are exhaust, tires, roof racks, trim panels and
( transmission.
Therefore, make sure that none of the following
conditions are the cause of the noise before
proceeding with a driveline
teardown and
diagnosis.
In certain conditions, the pitch of the exhaust
may sound very much like gear noise. At other
times, it can be mistaken for a wheel bearing
rumble.
Tires, especially snow tires, can have a high
pitched tread whine or roar, similar to gear
noise. Radial tires may have this characteristic.
Also, any non-standard tire with an unusual
tread construction may emit a roar or whine
noise.
Trim panels can also cause whistling or whining
noise.
Clunk may be a metallic noise heard when the

DIAGNOSIS AND TESTING
Noise Conditions
Gear noise is typically a howling or whining due
to gear damage or incorrect bearing preload. It
can occur at various speeds and driving
conditions, or it can be continuous.
Chuckle is a particular rattling noise that sounds
like a stick against the spokes of a spinning
bicycle wheel. It occurs while decelerating from
64
kmlh (40 mph) and can usually be heard all
the way to a stop. The frequency varies with
vehicle speed.
Knock is very similar to chuckle, though it may
be louder and occurs on acceleration or
deceleration. The
teardown will disclose what
has to be corrected.
Clicking, popping or grinding noises may be caused
by the following:
worn, damaged or incorrectly installed wheel
bearing, suspension or brake component.
Check and rule out tires, exhaust and trim items
before disassembling the transmission to diagnose
and correct gear noise.
The noises described under Road Test usually
( have specific causes that can be diagnosed by
observation as the unit is disassembled. The initial
clues are the type of noise heard on the road test
and driving conditions.
Vibration Conditions
Vibration at highway speeds may be caused by
the following:
out-of-balance front or rear wheels.
out-of-round tires.
Shudder or vibration during acceleration may be
caused by the following:
damaged powertrainldrivetrain mounts.
excessively high constant velocity (CV) joint
operating angles caused by incorrect ride height.
Check ride height, verify correct spring rate and
check items under inoperative conditions.
Road Test
I A gear-driven unit will produce a certain amount
of noise. Some noise is acceptable and may be
audible at certain speeds or under various driving conditions,
as on a newly paved asphalt road. The
slight noise is in no way detrimental and must be
considered normal.
The road test and customer interview (if available)
provide information needed to identify the condition
-
and give direction to the correct starting point for
diagnosis.
1. Make notes throughout the diagnosis routine.
Make sure to write down even the smallest bit
of information, because it may turn out to be the
most important.
2. Do not touch anything until a road test and a
thorough visual inspection of the vehicle have been carried out. Leave the tire pressures and
vehicle load just where they were when the
condition was first observed. Adjusting tire
pressures, vehicle load or making other
adjustments may reduce the
condition(s)
intensity to a point where it cannot be identified
clearly. It may also inject something new into
the system, preventing correct diagnosis.
3. Make a visual inspection as part of the
preliminary diagnosis routine, writing down
anything that does not look right. Note tire
pressures, but do not adjust them yet. Note
leaking fluids, loose nuts and bolts, or bright
spots where components may be rubbing
against each other. Check the load space for
unusual loads.
4. Road test the vehicle and define the condition
by reproducing it several times during the road
test.
5. Carry out the Road Test Quick Checks as soon
as the condition is reproduced. This will identify
the correct diagnostic procedure. Carry out the
Road Test Quick Checks more than once to
verify they are providing a valid result.
Remember, the Road Test Quick Checks may
not tell where the concern is, but they will tell
where it is not.
Road Test Quick Checks
1. 24-80 kmlh (1 5-50 mph): with light acceleration,
a moaning noise is heard and possibly a
vibration felt in the front floor panel. It is usually
worse at a particular engine speed and at a
particular throttle setting during acceleration at
that speed. It may also produce a moaning
sound, depending on what component is
causing it. REFER to Tip-in Moan in the
Driveline Noise and Vibration Symptom Chart.

DIAGNOSIS AND TESTING
2. AccelerationIDeceleration: With slow
acceleration and deceleration, a shake is
sometimes noticed in the steering
wheellcolumn,
seats, front floor panel, front door trim panel or
front end sheet metal. It is a low frequency
vibration (around
9-1 5 cycles per second). It
may or may not be increased by applying the
brakes lightly. REFER to
Idle
BoomIShakeNibration in the Driveline Noise
and Vibration Symptom Chart.
High Speed: A vibration is felt in the front floor
panel or seats with no visible shake, but with
an accompanying sound or rumble, buzz, hum,
drone or booming noise. Coast with the clutch
pedal depressed (manual transmission) or shift
control selector lever in "N" (NEUTRAL)
(automatic transmission) and engine idling. If
vibration is still evident, it may be related to
wheels, tires, front brake discs, wheel hubs or
front wheel bearings. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
4. Engine rpm Sensitive: A vibration is felt
whenever the engine reaches a particular rpm.
It will disappear in neutral coasts. The vibration
can be duplicated by operating the engine at
the problem rpm while the vehicle is stationary.
It can be caused by any component, from the
accessory drive belt to the clutch or torque
converter which turns at engine speed when the
vehicle is stopped. REFER to Shake and
Vibration While Driving in the Driveline Noise
and Vibration Symptom Chart.
5. Noise and Vibration While Turning: Clicking,
popping or grinding noises may be due to the
following:
worn, damaged or incorrectly installed front
wheel bearing.
damaged
powertrainldrivetrain mounts.
Road Conditions
An experienced technician will always establish a
route that will be used for all NVH diagnosis road
tests. The road selected should be reasonably
smooth, level and free of undulations (unless a
particular condition needs to be identified). A
smooth asphalt road that allows driving over a
range of speeds is best. Gravel or bumpy roads
are unsuitable because of the additional road noise produced.
Once the route is established and
consistently used, the road noise variable is
eliminated from the test results.
N0TE:Some concerns may be apparent only on
smooth asphalt roads.
If a customer complains of a noise or vibration on
a particular road and only on a particular road, the
source of the concern may be the road surface. If
possible, try to test the vehicle on the same type
of road.
Vehicle Preparation
Carry out a thorough visual inspection of the
vehicle before carrying out the road test. Note
anything which is unusual. Do not repair or adjust
any condition until the road test is carried out,
unless the vehicle is inoperative or the condition
could pose a hazard to the technician. After
verifying that the condition has been corrected,
make sure all components removed have been
installed.
Power Steering Conditions
c !
Check for the noise in the following conditions to
verify the customer concern.
Check for the noise in several temperature
conditions.
Is the noise from when the vehicle was new?
Can the noise be repeated constantly or is it
random?
Check the condition of the vehicle age, mileage
and service record.
Interview the customer to find the operating
condition in which the noise will occur. Test the
vehicle based on the
detail(s) from the customer
interview.
Follow the power steering operation noise
condition tables below, to find which condition
the noise will occur.
Power Steering Operation Noise Check
Step 1 : Check for NVH concerns from non-steering
components, which may sound like noises coming
from the steering system.
