piston grade reference (8 digits) is also shown.
Automatic Transmission
Number
The
serial number of the transmission unit is displayed on
a metal or bar code label attached to the LH side of the
transmission casing.
Veh
icle Identification
Dependent
upon market, the VIN and other info

door or on the body front upper crossmember. For certain mark ets, the VIN appears on a bar code label referred to as the
Certification Label and additionally carries the month and year of manufacture, vehicle weight data and paint and trim codes.
The VIN is also displayed on a plate visible through the windshie ld. It is essential that the vehicle identification number (VIN)
is quoted when ordering parts, and in all associated correspondence.

T
h
e date of manufacture (Build Date) of a vehicle is define
d as the calendar month and year in which the bodyshell and
powertrain are combined and the completed vehicle leaves the production line. For certain markets, VIN labels carry the
month and year of manufacture. For other markets, the vehicle Build Date is also displayed on a metal plate located at the
top of the battery tray in the trunk.
ANTI-T
HEFT LABELS
F
or
some markets, anti-theft labels bearing the VIN printed on
a special anti-forgery background are positioned on certain
body components. An additional anti-theft label is positioned on the LH side of the engine/automatic transmission casing.
Anti-theft labels must not be removed from a vehicle unless necessitated by component renewal.

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

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.

Op era
tion
As each road wheel r
i
ses, move
ment is transmitted through th e hub carrier assembly to the wishbone and axle shaft. The
corresponding rise of the wishbone compre sses the road spring and partially telescopes the shock absorber. During this
action, the spring absorbs result ing shocks and the shock absorber minimizes spring oscillation.
During cornering, vehicle weight is transferred to the outer road wheel with a resulting tendency for the inner wheel to lift.
On Supercharged and Sport Suspension vehicl es, a rear stabilizer bar assists in minimizing this tendency by transferring a
proportion of potential lift of the inner wheel to the outer wheel. This results in enhanced body stability with improved
cornering capabilities.
