. Disconnect vehicle battery ground lead.
. Support the vehicle at the rear.
. Disconnect main handbrake cable at compensator.
’Match mark‘ the FLEXIBLE COUPLING to the differential DRIVE FLANGE and remove fixings.
Remove fixings center bearing to crossmember and push drive shaft rear section forward to disengage from pinion
spigot.
CAUTION: Under no circumstances must the flexible coupling (or its fixings) be loosened or removed from the drive
shaft flange.
Support the drive shaft, do not allow it to hang.
9 ‘Match mark‘ the drive flange retaining nut to both the pinion and the drive flange (Fig. 1).
. Slacken the flange retaining nut approximately half a turn and retighten to the ‘match mark‘ noting the required force.
. Remove the retaining nut, washer and drive flange.
CAUTION: Use only special tools; 18G 1205 to restrict rotation and JD 156 to remove drive flange.
. Inspect the drive flange oil seal surface for damage corrosion or grooving and replace as necessary.
. Remove oil seal from differential case taking care not to damage the machined counterbore.
rn Clean seal counterbore.
. Using special tool JD 198 fit replacement oil seal to differential case ensuring that, seal is square, fully seated and
If the force does NOT exceed 135 Nm, the final drive unit MUST be replaced.
Do not use abrasive cloth, or paper, to remove imperfections from the seal surface.
the
lip spring is not dislodged.
Apply grease to drive flange seal diameter and refit the flange to the pinion in the original position.
U: Do not hammer the drive flange onto the pinion; pull down with the drive flange nut.
Tighten the drive flange nut to the original noted torque PLUS 10%.
* Check that the pinion spigot radial run-out is to specifica- tion.
Fitting and reassembly is the reversal of this procedure en
- suring that drive shaft fixings are renewed and that the
shaft is aligned in accordance with Sub-Section 9.2.
Correct the final drive oil level if required.
. Tighten all fixings to specification.

15.2.8 Odometer
With the ignition 'OFF' the odometer is permanently dis-
played but not illuminated. With the ignition 'ON' the odo- meter is displayed and also illuminated.
Trip information or driver information messages may be dis
-
played instead of the 'ODO'. By pressing the 'ODO' button
once or twice the trip and driver information messages can
be deleted and the
'ODO rdisplayed.
W. The odometer value is not stored within the LCD
module.
15.2.9 Trip Computev
This provides information on the vehicle's speed, fuel usage
and distance traveled
all of which are calculated by a micro
processor.
The controls, part of the fascia switch assembly, are located
on the right
-hand side pod positioned to the right-hand side
of the steering column.

15.2.10 Driver Information Messages
Two fault messages, FLUID - AIRBAG are displayed via the LCD in conjunction with relevant warning lamps.
If an
airbag fault exists or the brake fluid is low, a message will automatically be displayed on the LCD and the relevant
warning lights illuminated. Should both faults exist at the same time, each message is displayed alternatively for ap
- proximately 2 seconds.
Messages may becancelled
by pressing the 'ODO button which allowsthe LCD to return to its last displayed message.
The warning lamps will not be extinguished. If the fault is not repaired the message(s) and the warning lamp(s) will
be redisplayed when the ignition is switched on.
15.2.11 /llumination
Warning indicator lamp illumination is controlled by a microprocessor located inside the instrument panel.
The seven right
-hand warning indicators are primary warning lamps illuminating 'RED and the seven left-hand warn-
ing indicators are secondary warning lamps illuminating 'AMBER'
The eight lower lamps are
a mixture of status and warning lamps.
With the ignition
'OFF' the LCD is not illuminated.
With ignition
'ON' and side lights 'OFF' the LCD is illuminated at maximum brightness.
With the ignition on and side lights
'OFF' the LCD is dimmed as are the gauges.
The long
life type bulbs are enclosed by orange and brown coloured bulb holders which must never be interchanged.
Replacement bulbs must always be of the same colour.
CAUTIQN: Always dwonnect the battery ground lead before commencing with any instrument rsimwal procedure.
15.2.12 General Repair Notes
0 After lens removal do not rest instrument panel face down as this causes damage to the delicate gauge needles.
Avoid scratching the gauge faces and ensure cleanliness when handling the panel.
0 To minimize the risk of damage and contamination to the instrument panel, all repairs must be carried out in a non - static and dust -free environment. Avoid touching connector pins and pcb components to minimize
risk of static damage.
0 The instrument panel has two different types of bulb holders each of which must be located correctly when
changing the bulbs.

Body Systems & Body Repair
A4.1.5 GENERAL REPAIR NOTES
The following advice should be noted before ANY repair work is carried out.
0 Disconnect the vehicle battery ground lead (disconnect the alternator where electric welding is used) and take
note of the reconnection procedures as detailed in Section 15.
0 Where structural parts are straightened or renewed, a body alignment / straightening jig must be used.
0 Where appropriate, structural sections should be straightened by cold processes. Heat, especially excessive
heat, will reduce the strength of steels.
0 Repairs may only be carried out successfully, and any warranties protected, if genuine Jaguar replacement parts
and Jaguar approved materials are used.
0 Tools, procedures and facilities must be right for the job. Do not compromise the quality of the work by using
inappropriate methods.
0 All trim and electrical components in the locality of the repair must be removed or disconnected prior to panel
removal / replacement; this is especially important where hollow sections may contain harnesses, tubes or
foam, see section
A4.3.5.
0 The welding and gas processes detailed in the following sections are the only ones recommended by Jaguar
Cars Ltd.
0 Ensure that you have read and understood the safety related procedures in this and other relevant sections.
WARNING: DO NOT WORK
IN THE VICINITY OF A LIVE AIR BAG, REMOVE IT COMPLETELY. READ WORKING PRAC- TICES AIR BAG, SECTION 15. ANY SEAT BELT WHICH HAS BEEN WORN IN AN ACCIDENT MUST BE RENEWED. PLEASE SEE SECTION
AGE LOCATIONS. 13 FOR IMPORTANT INFORMATION REGARDING 'TEAR LOOP' SEAT BELTS / BUCKLES AND ANCHOR-
CAUTION: Electric arc welding should not be used on Jaguar vehicles. The high vottages produced by this process will cause irreparable damage to the electrical control and microprocessor systems.
A4.1.5.1 Welding and Gas Processes Special Notes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated,
metal.
The flanges of panels which are to be welded together must be clean, corrosion free and treated as appropriate,
with either weld-through primer or inter-weld sealer; use only materials and processes in accordance with the 'Body Seal-
ing and Preservation Manual' and relevant application areas in section A4.3.1.1.
See 'Zinc Coated Panels' section A4.2.
Generally, the resistance spot welding equipment used in the motor vehicle repair industry does not produce a weld
of equivalent strength to that of the manufacturer. Therefore, the expression 'single row of resistance spot welds'
means that the spots should be spaced on a pitch of
19mm to 25mm. This will usually result in more spot welds than
found in the original factory joint.
To remove resistance spot welds, a resistance spot weld cutter should be used.
If the new joint is to be MIG plug welded, the old resistance spot welds should be cut from the panel which is to be
retained and those holes used for plug welding.
Suitable holes may also be drilled or punched;
8,O mm dia for sections up to 1,6 mm, and 10,O mm dia for thicker sec- tions.
