Rear Suspension 171
Installation is a reversal of the removal procedure
with attention to the following points:

(1) When installing the stabilizer bar to the
knuckle assembly bushes, ensu re that the thicker bush
is installed to the front of the knuckle assembly. Install
the rear bush, washers and nut but do not tighten at
this stage. (2) Install the stabil izer bar mounting
brackets,
ensuring that the end with the large bevel is facing the
front of the vehicle. Tighte n the retaining bolts to the
specified torque. (3) Using a new gasket, install the intermediate
exhaust pipe to the catalytic converter, ensuring that
the earth wire terminal is installed, and tighten the
bolts securely. Install the exhaust mounting
retaining
bolt. (4) Install the rear wheels and lower the
vehicle
to the ground. With the wei ght of the vehicle on the
road wheels, tighten the stabilizer bar retaining nuts to
the specified torque.
8. REAR WHEEL ALIGNMENT
Specialized equipment is required to measure the
rear wheel alignment. It is therefore recommended
that the vehicle be referred to a specialist suspension
workshop or an authorized dealer for measurement
and adjustment. The suspension components should
be inspected and renewed as necessary prior to having
the wheel alignment checked. If any suspension com-
ponents are renewed, the re ar wheel toe out may be
temporarily adjusted as described below.

TO INSPECT
Examine the tread of the tires. Excessive or
uneven wear will indicate misalignment or damaged
or worn components. Refer to the Tire Wear Trouble
Shooting Chart in the Wheels and Tires section for
possible causes and renew the faulty components.

Badly worn tires should be renewed prior to
having the wheel alignment checked.

TO CHECK AND ADJUST TOE OUT
NOTE: The following procedures are only a
temporary measure. Th e vehicle should be
referred to a specialis t suspension work-
shop or authorized dealer for accurate
measurement and adjustment.

(1) Position the vehicle on a level floor and
bounce the vehicle several tim es to settle the suspen-
sion. (2) Move the vehicle forward approximately 5
meters, with the front wheels straight ahead, to settle
the tires and suspension to the normal running
position.
(3) Place a chalk line across both tire treads at a
point equivalent to the stub axle height and to the rear
of the suspension. Place a vertical mark at the chalk line in the
centre of each tire.

(4) Using a telescopic gauge or tape measure,
measure the distance between both vertical marks and
record the measurement. (5) Move the vehicle forward until the marks are
to the front of the suspen sion, with the horizontal
marks at the same height as in operation (3). (6) Measure the distance between both vertical
marks. (7) The difference between the two measure-
ments will be the amount of toe out of the rear wheels. (8) If the toe out is not as specified, adjust the
rear control arm cams as follows: (9) Measure the distance between the inner
wheel rim and the adjusting flange on the rear
crossmember. Measure the distance on the other side
of the vehicle in the corresponding positions. (10) If the measurements are equal, loosen the
cam nut and turn the cam bolt to move the rear
control arm half the distance required to bring the
rear wheel toe out to specifications. Repeat this
operation on the other side of the vehicle.
(11) If the measurements obtained in operation
(9) are not equal, proceed as follows:
(a) If the toe out is less than specifications,
decrease the length of the shorter arm.
(b) If the toe out is greater than specifications,
increase the length of the longer arm.
NOTE: The toe out will alter approximately
2 mm with each graduation of the adjusting
cam.

Using the radio/cassette removal tools during removal of the unit.
Construct the special tools as illustrated,
insert both tools into the release holes on the radio/
cassette and carefully withdraw the radio/cassette
from the mounting bracket.
Disconnect the wiring harness terminal plug
and remove the radio/cassette.
Installation is a reversal of the removal procedure
with attention to the following points:

Remove the special tools from the radio/
cassette, connect the wiring harness terminal and push
the radio/cassette into the mounting bracket. Install the release hole covers on each side
of
the radio/cassette.

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.
Maneuver the headlamp inner side out first
and remove the headlamp from the vehicle. Installation is a reversal of the removal procedure.

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.

When installing a trailer socket, it may be neces-
sary to replace the original vehicle flasher unit with a
heavy duty unit to maintain the flash rate in accor-
dance with local regulations. Local regulations may
also require the installation of a dashboard mounted
repeater lamp.

Should the trailer socket and plug not be matched,
adaptors can be made or obtained to facilitate con-
nection.

TO INSTAL TRAILER SOCKET.
The minimum materials required are a trailer
socket, mounting bracket, seven core flex, insulated
wiring connectors and a rubber grommet.

(1) Disconnect the negative battery terminal.
(2)Locate the wiring harness for the lamps at
the rear of the vehicle.

For five pin sockets and plugs, use the following
standard trailer wiring code:

Terminal No.CircuitColor2 Left turn signal lampYellow
3Earth White
5 Ri
ght turn signal lampGreen
6Stop lamp Red
7 Tail lam
p Brown

Minimum material needed for wiring up a trailer.
Utilux trailer socket and plug shown.
(3) Identify the wires for the right turn signal
lamp, left turn signal lamp, tail lamp, stop lamp,
reverse lamp and earth. Use the vehicle wiring
diagram in this section to determine the wire color
for each lamp circuit.
(4)Connect the seven core flex to the various
lamp wires using insulated connectors.
For seven pin sockets and plugs, use the following
standard trailer wiring code:

Terminal No.CircuitColor1 Left turn signal lamp Yellow
2 Reversing lamp Black
3EarthWhite
4 Right turn signal Green

5Electric brakesBlue
6 Stop lampRed

For six pin sockets and pl ugs, use the following
standard trailer wiring code:
Terminal No.CircuitColor1 Tail LampBrown
2 Left Turn Signal Lamp Yellow
3Right Turn Signal LampGreen
4 Stop LampRed
5AuxilaryBlue
6 Earth White

(5) Drill a suitably si
zed hole through the vehicle
floor and install a rubber grommet to the hole.

NOTE: Before drilling the hole, check
whether there is an existing hole which may-
be used. Ensure that a rubber grommet is
installed to prevent chafing of the wires.

Pass the seven core flex through the rubber
grommet. Cut the seven core flex to the required length
and slide the dust cover onto the flex. Remove approximately 15 mm of insulation
from each wire in the flex.
Connect the wires of the seven core flex to
the terminals of the socket, using the standard wiring
code and following the socket manufacturers connec-
tion procedure. Assemble the socket and install the dust cover
to the rear of the socket. Install the mounting bracket as close as
possible to the tow bar ball and high enough to
maintain vehicle ground clearance. Install the socket to the mounting bracket.
Connect a trailer plug to the socket and test
for correct lamp operation.
TO INSTAL TRAILER PLUG

The minimum materials required are a trailer
plug, seven core flex and insulated wiring connectors.

The installation procedure for the trailer plug is
similar to that for the socket with attention to the
following points:

Connect the trailer wiring to the plug accord-
ing to the standard wiring color code and the plug
manufacturers instructions. Use a suitable length of
seven core flex and insulated connectors should the
trailer wiring not be long enough.
If the trailer wiring does not conform to the
standard color code, identify each circuit as follows: (a) Locate the trailer earth wire.
