brake JAGUAR X308 1998 2.G User Guide

Wh en t
he vehicle is being reco
vered by rear suspended tow:
The ignition key must be remo ved from the ig
nition switch to lock the stee
ring with the front wheels facing straight
ahead.
The re ar
wheels must be
correctly positioned in the lifting cradle and securely tied down.
Em
ergency Towing
WARNING: IF THE

ENGINE IS NOT
RUNNING, THE STEERING WILL BECOME HEAVY AND THE FORCE NECESSARY TO
EFFECTIVELY APPLY THE BRAKES WILL BE GREATLY INCREASED.
• CAUTIONS:
A vehicle with a defective transmission must be towed by rear suspended tow.
The vehicle towing point is not suit able for use with a solid tow-bar.
Do not use the crossbeam tie bar as a towing location.
When the vehicle is being towed on its own wheels:
Loc a
l regulations for the towing of ve
hicles must be followed. In some co untries the registration number of the
towing vehicle and an 'On Tow' sign or warning triangle must be displayed at the rear of the towed vehicle.
The gear s
elector lever
must be in Neutral.
The
ignition switch must be in positi
on II to release the steering lock and make the direction indicators, horn and
stop lamps operate.
A di
stance of 0.8 km (0.5 mi
le) must not be exceeded.
A spe
ed of 48 km/h (30 mph) must not be exceeded.
The tow rope must be attached using th
e towi
ng location provided; refer to Front Towing Point in this section.

Gene
ral Procedures


1.
WARN
INGS:
ENSURE THAT THE VEHICLE IS STANDING ON FIRM, LEVEL
GROUND.
DO NOT START OR RUN THE ENGINE WHILE THE VEHICLE
IS ONLY SUPPORTED BY THE VEHICLE JACK.
Position the jack at the appropri ate front or rear jacking point.
Put the parkin
g brake ON and
the transmission in Park.
Chock the wh
eels to prevent movement of the vehicle.

2.
Locat e
the arm of the jack securely in the jacking socket.
R
e
move the rubber cover from the socket.
3. Raise/lower the vehicle using the jack ratchet handle.
4. Remove the jack from the jacking point.
Fi
t the rubber cover to the jacking socket.

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.
