Gen
eral Procedures
• NOTE: Before any work is commenced, th e vehicle must be checked to establish that it conforms to the Jaguar original
specification, e.g. wheels, ti res, tire pressures, etc.
• NOTE: The vehicle must be unladen and the fuel tank full when measuring suspension geometry.

1.
Road test the vehicle to establish the exact nature of the
complaint, e.g. pulling to one side, wander.
2. Measure the suspension geometry, fill in the 'Suspension
Geometry Record Form', and co ntact Jaguar Technical Support
for assistance.
3. Technical Support will give advice on the course of action to be
taken to rectify the problem.
4. Each lower wishbone pivots on and is secured to the front
crossbeam by two fulcrum bolts. A circular eccentric flange
formed under the hexagonal head of each fulcrum bolt, has
raised graduation marks to indicate radial position. A washer
with a 'D' shaped hole locates on a flat on the threaded section
of each bolt. This ensures that the washer rotates with the bolt,
maintaining an eccentric position corresponding with the
flanged head. The outer face of the washer is punch marked,
ensuring correct instal lation with the chamfered face inwards.
This permits the washer to rotate freely in the crossbeam cam
reaction plate during a djustm ent. Each fulcrum bolt and
washer are secured by a self locking nut.
On rotation of the bolt, lateral movement of the eccentric flange
and washer is restricted by the cam plate faces, forcing the bolt
shank to move laterally in the crossbeam slots. Lateral
movement of the bolt shank re sults in corresponding inward
and outward movement of th e wishbone arm, effecting
adjustment of wh eel alignment.
Rotation of the front fulcrum bolt principally adjusts wheel
caster angle, with a small amount of camber angle change.
Adjustment of the rear fulcrum bo lt mainly alters wheel camber
angle with a small amount of caster angle change.
On vehicles with VIN up to 833124, fulcrum bolt eccentric
flanges have raised graduation marks representing 15 degree
increments of bolt rotati on from 0 to 90 degrees.
On vehicles with VIN from 833125, the fulcrum bolt graduation
marks represent bolt shank ho rizontal movement in 1mm
increments from 0 to 3mm.
The upper wishbone and fulcrum shaft are not adjustable and
play no part in steering geometry adjustment.

O
ne locking wheel nut is fitted to each road wheel and can on
ly be removed by using the correctly coded socket. For road
wheels with exposed wheel nuts, each locking wheel nut is provided with a cover, which is removed using the cover removal
tool.
Locking wheel nuts have different coded keyway combinations with corresponding coded sockets. The correct socket, and
cover removal tool are supplied with the vehicle toolkit. Sets of sockets are available to Jaguar dealers.
Temporary Spare Wheel
•
NOTE: When using this type of spare wheel note that:
Speed

must not exceed 80 km/h (50 mph).
The normal ro

ad wheel must be reinstalled as soon as possible.
On

ly one temporary wheel may be installed to the vehicle.
Tracti

on control (where fitted
) must be switched OFF.
In certain markets, the spare wheel supplied with the vehicle is of the temporary-use type, it is narrower than the normal
road wheel and takes up less room in the luggage compartment.
Tire
s
The
radial ply tires shown in the 204-04
Specification Section are recommended by Jaguar to meet the high speed
performance of the vehicle. Only tires of identical specification may be fitted as replacements. Unde r no circumstances must
cross-ply tires be fitted.
Tire Inflation Pressures
Al
l recommended tires, including winter tire
s, must be inflated to the pressures shown in the 204-04 Specification Section.
Inflation pressures must only be checked when the tires are cold.
Tire Replac
ement and Wheel-Interchanging
W
hen renewal of tires is necessary, it is
preferable to fit a complete set. If two replacement tires are fitted (to one axle),
they must be of the same manufacturer and type as those on the other axle.
No attempt must be made to interchange wh eels from the front to the rear or vice-versa, as wear produc es a characteristic
pattern on each tire depending upon its po sition on the vehicle. If this position is changed after wear has occurred, the
performance of the tire w ill be adversely affected.
It should be remembered that new tires must be balanced befo re installing to the vehicle.
Win
ter Tires
•
NOTE: Speed must not exceed 210 km/h (131 mph) when winter tires are installed.
Jaguar recommended winter tires as specified in 204-04 Specification Section must only be fitted in complete four-wheel
sets of the same type and size.
Snow Chains and Spike Spider Traction System

Jagu
ar recommended snow chains, must on
ly be installed when using 16 inch wheels with 255/60 R16 winter tires.
• NOTE: When using snow chains or the spike spider traction system, note that:
Snow ch
ains and the spike spider
traction system must only be fitted to the rear wheels.
O
nly Jaguar recommended snow chains and spik
e spider traction system must be used.
The m
aximum permissible speed with winter tires and snow chains or the spike spider traction system fitted is 48
km/h (30 mph).
Tracti
on control (where fitted) must be
switched OFF when using snow chains or the spike spider traction system.

iagnosis and Testing
General Not

es
1.
1. Factory in
stalled tires and wheels are designed to provide optimum ride and ha
ndling characteristics when inflated
to the recommended inflation pressures, with vehicle loads not exceeding the full-rated load capacity.
2. 2. Correct tire pressures and driv ing technique have an important influence on tire life. Heavy cornering, excessively
rapid acceleration and unnecessary sharp braking increase tire wear.
3. 3. Replacement tires should follow the recommended:
Size
.
Speed

rating.
Load range. Radial c

onstruction type.
4. 4. The use of any other size or type of wheel / tire may seriously affect:
Safety. Ri
de.
Handlin

g.
Speed

ometer / odometer calibration.
Vehi

cle ground clearance.
Ti
