gine Number
The en
gine number (10 digits) is stamped on a raised pad on th

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
rmation is displayed on a label located ei ther on the rear edge of the LH front
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.

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

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.

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.

Two tie rods are fitted between top rear of the final dr ive casing and the front of the wide mounting bracket.

Parts List
Description
The
type 14 HU final drive assembly is a hypoid unit with th
e pinion arranged on the cross-car centerline. The driveshaft
coupling utilizes a cassette type pinion oil seal, which is an in tegral part of the pinion flange. This type of seal cannot be
separated from the pinion fl ange and therefore may only be renewed as a complete seal / flange assembly
The axle shafts are driven by the output flanges which rotate on sealed bearings , these assemblies being retained in the
final drive unit by circlips.
