Brake Testing
A WARNING:When brake testing, avoid
breathing the fumes from hot brakes, this
may contain asbestos dust which is
hazardous to health. Failure to follow this
instruction may result in personal injury.
For additional information, refer to: Health
and Safety Precautions
(1 00-00 General
Information, Description and Operation).
CAUTIONS:
A Avoid brake testing on busy roads where
it may cause inconvenience or danger to
other road users.
A Brake testing which includes heavy brake
applications should not be carried out with
new brake
padsldiscs or liningsldrums
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 brake disc or brake drum that feels
hot or is appreciably hotter than the others,
indicates that the brake is binding.
After completion of the test, check for:

100-04-5 Noise, Vibration and Harshness 100-04-5
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.

100-04-6 Noise, Vibration and Harshness 100-04-6
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.

DESCRIPTION AND OPERATION
Front Suspension
Overview
N0TE:During installation of the front wheel bearing
it is important to adhere to the specified installation
position, as the anti-lock brake system
( ABS )
sensor ring is located in the wheel bearing. A
coloured rubber ring is provided to indicate the
correct installation position. If the wheel bearing
were to be installed incorrectly then this would
cause failure of the ABS
.
A newly developed Mc-Pherson front suspension
with L-shaped lower arms is used. These lower
suspension arms are linked via large rubber
mountings to a reinforced and extremely rigid front
axle crossmember.
The ball head between the lower suspension arm
and the suspension strut is secured with three
rivets. Toe-in is adjusted via adjustable track rods.
The lower suspension arms can only be replaced as a complete unit.
