Torque Specifications
Torque sp
ecifications are shown in maintenance procedure illustra
tions and also in the torque specifications chart located at
the front of the relevant section.
Disconnecting/Connecting the Battery
Ow ing t
o the electronic components used on the vehicle, it is important that the battery is disconnected when specified in a
maintenance procedure.
When the battery is connected, the specified procedure must be followed, to ensure the correct operation of all vehicle
systems; refer to Section 414-01.
Use of Control Modules
Control modu les may
only be used on the ve
hicle to which they were originally fitted. Do not attempt to use or test a control
module on any other vehicle.
Function
al Test
On
completion of a maintenance procedure, a thorough test should be carried out, to ensu
re that the relevant vehicle
systems are working correctly.
Protecting the Vehicle
Al ways
fit covers to protect
the fenders before commencing work in the engi ne compartment. Cover the seats and carpets,
wear clean overalls and wash hands or wear gloves before working inside the vehicle. Avoid spilling hydraulic fluid,
antifreeze or battery acid on the paintwork. In the event of spillage, wash off with water imme diately. Use polythene sheets
in the trunk to protect carpets. Always use the recommended service tool, or a satisfactory equivalent, where specified.
Protect temporarily exposed screw thread s by replacing nuts or fitting caps.
Preparation
Before disassembly, clean the surrounding ar ea
as thoroughly as possible. When co
mponents have been removed, blank off
any exposed openings using grease-proof paper and masking tape. Immediately seal fuel, oil and hydraulic lines when
separated, using plastic caps or plugs, to prevent loss of fluid and the entry of dirt. Close the open ends of oilways, exposed
by component removal, with tapered hardw ood plugs or readily visible plastic plugs. Immediately a component is removed,
place it in a suitable container; use a se parate container for each component and its associated pa rts. Before dismantling a
component, clean it thoroughly with a recommended cleaning agent; check that the agent will not damage any of the
materials within the component. Clean the bench and obtain ma rking materials, labels, containers and locking wire before
dismantling a component.
Dismantling
O b
serve scrupulous cleanliness when dismantling components,
particularly when parts of the brake, fuel or hydraulic
systems are being worked on. A particle of dirt or a fragment of cloth could caus e a dangerous malfunction if trapped in
these systems. Clean all tapped holes, crev ices, oilways and fluid passages with compressed air. Do not permit compressed
air to enter an open wound. Always use ey e protection when using compressed air.
Ensure that any O-rings used for sealing are correctly refitted or renewed if disturbed. Mark mating parts to ensure that
they are replaced as dismantled. Whenever possible use markin g materials which avoid the possibilities of causing distortion
or the initiation of cracks, which could occur if a center pu nch or scriber were used. Wire together mating parts where
necessary to prevent accidental interchange (e.g roller bearing components). Tie labels on to all parts to be renewed and to
parts requiring further inspection before being passed fo r reassembly. Place labelled parts and other parts for rebuild in
separate containers. Do not disc ard a part which is due for renewal until it ha s been compared with the new part, to ensure
that the correct part has been obtained.

Upper
Wishbones
Each
upper wi
shbone assembly is a on
e-piece steel forging incorporating:
A pres
s-fit ball joint.
Press-fi

t bushes for location of the upper fulcrum bolt.
Lower Wishbones
Each l
o
wer wishbone comprising
forged steel front and rear arms bolted together, incorporates:
A p
ress-fit ball joint in the outer extremity of the rear arm.
Press-f
i
t bushes for location of the lower fulcrum bolts
Locati
on for the shock absor
b
er lower mounting plates.
Vertica l Links

The vertical
links are of forged steel
wi
th integral steering arms. Each is suppo rted between the upper and lower wishbones
by two ball joints and carries:
Front hub

Brake ca
liper and disc shield assembly

ABS se
nsor
.
Front Hub
s

Each f
o
rged steel front hub accommodates sealed for life cartridge
type wheel bearings, and carries:
The brake rotor assembl
y.
A
h
ub nut with toothed, integral ABS rotor.
Su
s
pension spring pi
n locking device.
Front Road
Springs
The road spri
ng
s are of coil type with their
rating dependent upon vehicle specification
Ea
ch spring is installed between the suspension crossbeam location and the lower wishbone spring pan.
Ru
bber seats ar
e installed betw
een the spring and the crossb eam and the spring pan.
Front Shock A
bsorbers
Th
e
shock absorbers are telescopic hydrau
lically operated units. Optional adaptive damping units incorporate a solenoid-
operated control valve at their upper extremity.
Each shoc
k absorber is installed between the lowe
r wishbone rear arm and a recess in the body.
The l
o
wer end of the shock absorber is se
cured to plates on the wishbone by a bolt that also serves as a pivot.
The u
pper en
d of each shock absorber is secured to the body location by a single nut.
Front Sta
b
ilizer Bar
A
front stabil
izer bar installed on all vehicles
is rated according to suspension specification.
Opera
tion
As each road wheel r
i
ses, move
ment is transmitted through the vertical link assembly to the lower wishbone. The resulting
rise of the wishbone compresses the road spring and partially telescopes the shock absorber. During this action, the spring
absorbs associated shocks and the shock absorber minimizes sprin
g os c
illation.

Du

ring cornering, vehicle weight
is transferred to the outer road wheel with a resulting tendency for the inner wheel to lift.
The stabilizer bar assists in minimizing this tendency by transf erring a proportion of potential lift of the inner wheel to the
outer wheel. This result s in enhanced body stability with improved corner ing capabilities.
