(2) Ensure that the stabilizer bar links are in
good condition. Renew if necessary.
(3) When installing the stabilizer bar ensure that
the links are installed perpendicular to the control arm
with the ball joint socket face parallel to the end of the
stabilizer bar. (4) Ensure that the brackets are installed with
the flat portion facing towards the front of the vehicle.
Tighten the retaining bolts securely.
7. SUSPENSION AND STEERING ANGLES

ADJUSTMENT
NOTE: Extensive knowledge and special-
ised equipment are required to measure and
correct the suspension and steering angles
with the exception of the front wheel toe in.
Therefore, as it is not a viable proposition
for the average person to carry out a com-
plete wheel alignment, the vehicle should be
taken to a wheel alignment specialist.

Prior to carrying out a wheel alignment, a thor-
ough inspection of the steering linkage, front hub
bearings, ball joints and suspension units should be
carried out. Faulty components should be renewed or
repaired as necessary.

The tread of the front ti res should be examined
for excessive or uneven wear as certain conditions of
tire wear are indicative of damaged or worn compo-
nents in the suspension, stee ring linkage and/or wheels
and bearings. Refer to the heading Tire Wear Trouble
Shooting in the Wheels and Tires section. If the tires
are found to be defective, renew them with serviceable
lyres.

TO CHECK AND ADJUST TOE IN/OUT
NOTE: The vehicle s hould be unladen ex-
cept for the normal amount of fuel and with
the tires inflated to the correct pressures.

(1) With the vehicle on a level floor, raise the
front of the vehicle and s upport it on chassis stands.
(2) Spin each front wheel in turn and using a
piece of chalk, mark a line around the periphery of
each tire as near to the centre as possible. (3) Lower the vehicle to the ground and bounce
the front several times to stabilize the suspension. (4) Set the wheels in the straight ahead position.
(5) Mark the centre chalk line on both tires at a
point approximately 200 mm above the floor and
forward of the suspension. (6) Using a tape measure, measure and record
the distance between the two marked points on the
tire centers.

Diagram indicating the front wheel toe in. Refer to
Specifications for the correct difference between
measurement A and B.
(7) Maintaining the wheels in the straight ahead
position, roll the vehicle forward until the marks are
the same distance from the floor but to the rear of the
suspension. (8) Again using the tape measure, measure and
record the distance between the marks on the tires.
(9) The difference between the front and rear
measurement will give the correct toe in/out reading.
If the larger measurement is at the front, the wheels
are in a toe out position. If the reverse is true, the
wheels are in toe in position. Compare the reading
obtained with the figure given in Specifications.
(10) If adjustment of the to e in/out is necessary,
loosen the tie rod locknuts on both sides. (11) Remove the retaining clips from the small
end of the steering rack rubber boots. (12) Turn the tie rods as required until the correct
toe in/out reading is obtained.
NOTE: It is important to turn each tie rod
equally to maintain the central position of
the steering gear. Ensure that the lengths of
the tie rods are the same.

(13) Tighten the tie rod locknuts to the specified
torque without changing the positions of the adjusters.
(14) Install the retaining clips to the small end
of
the steering rack rubber boots, ensuring that the boots
are not twisted.

1. REAR SUSPENSION TROUBLE SHOOTING
REAR END NOISE
( 1 ) Defective suspension unit or mounting: Re-
new the faulty components.

(2) Loose or worn control arm bushes or pivot
bolts: Check and tighten or renew the worn compo-
nents. (3) Broken coil spring: Renew the coil spring,
preferably in matching pairs. (4) Worn rear hub bearing: Check and renew the
hub bearing as necessary. (5) Loose or worn stabilizer bar bushes: Check
and tighten or renew the worn components.
NOTE: As a quick guide to suspension unit
condition, bounce the vehicle up and down
(one side at a time) and observe if the vehicle
comes to rest in a single movement If the
vehicle bounces two or three times before
coming to rest the susp ension unit is suspect.
If suspect, remove the suspension unit and
check for fractures and leaks. If the
suspension unit is found to be unserviceable,
it is good practice to install two new
suspension units as a matching pair.

To check the control arm bushes or pivot
bolts, insert a lever between the suspect unit
and its mounting and lever the unit back
and forth checking for excessive movement.

Check the coil springs visually for breaks.
If the spring is found to be unserviceable, it
is good practice to install two new coil
springs as a matching pair.

Rear hub bearing noise can be diagnosed
by raising and supporting the rear of the
vehicle, spinning one wheel at a time and
listening for a rumbling noise.

POOR OR ERRATIC ROAD HOLDING ABILITY
(1) Low or uneven tire pressure: Inflate to the
recommended pressures.
(2) Incorrect rear wheel alignment: Check and
adjust the rear wheel alignment as necessary.
(3) Defective suspension unit: Renew the faulty
suspension unit, preferably in pairs. (4) Loose or broken stabilizer bar: Check and
tighten or renew the faulty components.
Check the stabilizer bar bushes and mounting rubbers
for wear and deterioration.

Rear Suspension 167

NOTE: When a wheel bearing has been
removed from the hub it must be renewed.

(5) Press the new bearing into the hub, ensuring
that pressure is not exerted on the inner race of the
bearing and that the bearin g seal is not damaged. Do
not apply grease or oil to the mating surfaces of the
bearing and the hub.

NOTE: When installing the new bearing,
the press load must not exceed 3 tonnes.

(6) Inspect the snap ring for wear or cracks and
renew as necessary. Install the snap ring into the hub
ensuring that it is secur ely located in the groove.
(7) Apply multi-purpose grease to the bearing
sealing lip and install the hub as previously described.

TO REMOVE AND DISMANTLE
(1) On hatchback models, remove the rear par-
cel shelf and lower the rear seat backrests. Remove the
parcel shelf side panel re taining screws and remove
the relevant side panel.
(2) On sedan models, prise out the parcel shelf

the suspension unit and disengage the hose from the
suspension unit. (5) Support the weight of the knuckle assembly
and remove the bolts and nuts securing the suspension
unit to the knuckle assembly.
(6) Remove the nuts securing the suspension
unit to the body panel and maneuver the suspension
unit from the vehicle. (7) Thoroughly clean the suspension unit and
secure it in a soft jawed vice.
(8) Remove the dust cap from the upper mount-
ing and while holding the end of the piston rod with
an adjustable spanner, loosen the upper mounting
retaining nut. Do not re move the retaining nut.
(9) Using a suitable spring compressor, com-
press the coil spring and remove the upper mounting
retaining nut and washer. (10) Remove the upper mounting, insulator and
spring seat from th e suspension unit.
(11) Withdraw the upper insulator, coil spring,
lower insulator and dust cover from the suspension
unit. (12) Check the coil spring for cracks, deformation
and damage. Compare the free length with a new coil
spring and renew as necessary.

HEADLAMPS
To Remove and Install
Disconnect the negative battery terminal.
If removing the drivers side headlamp on 1.8
liter engines, remove the bo lt securing the air cleaner
intake duct and remove the air cleaner intake duct.

Dismantled view of the headlamp assembly.
Remove the radiator grille as described in
the Body section. Remove the bolt and nut from the front and
rear of the inner headlamp. Remove the side indicator lamp assembly
and remove the bolts from the side of the headlamp.

To Adjust Headlamp Aim
Ensure that the tires are inflated to the
correct pressure and that the vehicle is positioned on
level ground.
The vehicle should be unladen, with a full
fuel tank and the driver sitting in the vehicle. When using a headlamp aiming machine,
refer to the manufacturers instructions for equipment
being used.
