VEHICLE IDENTIFICATION AND GENERAL SPECIFICATIONS

1. VEHICLE IDENTIFICATION
When purchasing spare parts or when
registering
or insuring a vehicle, it may be necessary to quote
various vehicle identification codes. The location of
these codes are as follows: The Engine Number is stamped on the front
face
of the engine block below No. 4 spark plug. The Chassis Number is stamped on the bulkhead
above and to the right of the brake booster. The Vehicle Identification Plate is located on the
bulkhead to the left of the MAP sensor and contains
codings relating to body style, engine capacity,
model,
transaxle type, engine number, paint, trim and build
date. The Compliance Plate contains information on
the vehicle make, model, month and year of manu-
facture, chassis number, seating, capacity and the
Australian Design Rules (ADR) with which the vehi-
cle complies. This plate is affixed to the bulkhead
above and to the left of the brake booster. The Tire Placard, which is located on the inside
of the glove compartment, contains information
on
the tire size, rim size, tire pressure and load ratings.

24 Wheels and Tires


When the tire tread groove depth is less than 1.5
mm, or when the tire is worn to the point where the
tire wear indicators are level with the tread surface,
the tire should be renewed.
To preserve tire life it is good policy to periodi-
cally have the front wheels balanced and the front end
alignment checked on a reliable wheel alignment
machine.

The wheel and tire assemblies may be rotated at
20 000 km if desired. Rotation of the wheels and tires
will increase the period between tire renewal. Radial
tires should not be cross changed, they should be
changed from front to rear on the same side.


Tire rotation diagram. If desired, the wheel and tire
assemblies may be rotated every 20 000 km in the
manner shown. Vector SSS tire rotation not to include
spare wheel.
The air pressure in the tire is probably the single
most important aspect of tire care. Too little or too
much pressure in the tire can cause rapid wear or
complete failure through overheating. Where possible
the tire pressures should be checked and adjusted
when the tires are cold.

As a rule, different tire types, tread patterns or
sizes should never be used on the vehicle at one time.
All the tires on the vehicles, including the spare
should be a matched set to prevent the vehicle
behaving erratically under certain conditions. Under
no circumstances mix radial ply and conventional ply
tires.

1. FRONT SUSPENSION TROUBLE
SHOOTING

FRONT END NOISE
(1) Loose upper suspension mounting or piston
rod: Tighten the mounting or piston rod nuts. (2) Loose or worn suspension unit lower ball
joint: Tighten or renew the lower ball joint.
(3) Noise in the suspension unit: Renew the
faulty suspension unit, preferably in pairs.
(4) Worn or loose steering gear: Overhaul the
steering gear assembly. (5) Worn front hub bearings: Renew the hub
bearings:
(6) Loose or defective stab ilizer bar, control arm
or mountings: Check, tighten or renew the mounting
rubbers.

Check the ball joints for wear and deterioration.
(7) Worn stabilizer bar link ball joints: Renew
the stabilizer bar links.
(8) Drive shafts worn or insufficiently lubri-
cated: Check the lubricant and the dust boots and
renew as necessary. (9) Drive shaft splines in the hub or the
differential worn or dama ged: Check and renew as
necessary.

NOTE: To check the front suspension com-
ponents for wear, raise the front of the
vehicle, support it on chassis stands and
allow both front wheel to hang free. With an
assistant pushing and pulling the front
wheels in and out at the top and then at the
bottom, check for excessive looseness at the
front hub bearings and lower control arm
inner pivot bushes. Noise or vibration in the
front end can also be caused by excessive
tire or wheel unbalance. Drive shaft joint
noise is usually more pronounced when
moving slowly with the steering on full lock.

POOR OR ERRATIC ROAD HOLDING
ABILITY

(1) Low or uneven tire pressures: Inflate the
tires to the recommended pressures.

(2) Defective suspension unit: Renew the faulty
unit, preferably in pairs.

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.
