Recall R136 - Front Lower Ball Joints - Check Torque or Replace
Remove and destroy Bulletin S204-R136, dated 11/00. Replace with this Bulletin.
Revisions are shown with asterisks and black bars.
Issue:
As a result of ongoing process assessments, Jaguar has identified a safety-related defect on a number of S-TYPE vehicles.
On the vehicles involved, it is possible that an under-torque condition may exist on the front lower ball joint assembly This may result in a high
bending fatigue loading condition on the joint. In some cases the high bending loads could result in a fracture in the first thread of the ball stud that
could then lead to separation of the lower control arm from the vertical link.
Jaguar has made the decision to recall all S-TYPE vehicles in the above VIN range to check and, if necessary, replace the front lower ball joint. If
replacement is required, the easiest way to do this is to replace the complete vertical link assembly This work will be performed free of charge to the
customer.
*Only a very small number of the vehicles checked will require replacement parts.*
*WARNING:
NO DEALER STOCK SHOULD BE RELEASED UNTIL THIS CHECK AND ANY NECESSARY RECTIFICATION IS CARRIED OUT.
Customer vehicles, with a VIN prior to L92349, MUST be checked before releasing the vehicle to the customer.*
Jaguar is writing to all affected customers in North America (copy of letter is shown) requesting them to contact an authorized Jaguar Dealer as soon
as possible to arrange for the lower ball joint assembly to be checked and, if necessary, replaced at the earliest opportunity.

Warranty Information
Action
Check and, if necessary, replace the required components on all S-TYPE vehicles that are within the affected VIN range.
The workshop procedure for checking vehicles, as well as, for replacing components is outlined in this bulletin.
Jaguar has shipped a torque wrench to dealers that makes it possible to perform this check without the need to remove the wheel and tire assembly
By not removing the wheel and tire assembly the current dynamic balance characteristics will be retained.
LOWER BALL JOINT SECURING NUT TORQUE CHECK
1. Set torque wrench to 80 Nm and apply to the lower ball joint retaining nut (Illustration 1).
2000 Jaguar S-Type (X200) V6-3.0L Page 48
Note:
Hold the ball joint stud with a suitable wrench to prevent possible rotation while performing the 80 Nm check (Illustration 2).
2. If the torque wrench reaches 80 Nm without moving, reset the torque wrench to 150 Nm and torque tighten the nut.
Note:
To show that the retaining nut has been tightened to 150 Nm, a painted identification mark must be added to the nut.
3. If the retaining nut moves prior to reaching 80 Nm or the nut is visually loose, then the vertical link assembly will have to be replaced.
^ Dismantle the vertical link (ball joint) and inspect the lower arm, checking the stud-through hole for damage caused by looseness.
Note:
Also check for deterioration of the cone face; e.g. pitting, scoring or an elliptical shape.
^ If the arm is damaged the lower arm will need to be replaced along with the vertical link.
Note:
After replacing the lower arm, vertical link or both, the painted identification mark needs adding to the retaining nut.
REPLACING LOWER BALL JOINT/VERTICAL LINK
If one or both lower ball joint securing nuts fail the check, the corresponding vertical link will need to be replaced using the following
procedure:
1. Remove front brake disc for access. See JTIS 206-03 (SRO 70.10.10).
2. Remove the three push-pins from the inner fender skirt, then position the skirt aside to access the anti-lock brake (ABS) sensor electrical
connector.
*Caution:
Do not remove the ABS sensor and wire from the hub assembly. The sensor 0-ring may be damaged.*
3. Disconnect the ABS sensor from the vehicle wiring harness. Detach the ABS sensor wiring from the retaining clips.

4. Loosen and remove front hub securing bolts (Illustration 3).
5. Remove front hub from vertical link (Illustration 4).
6. Loosen, but do not remove upper wishbone ball joint securing nut (hold ball joint stud to prevent rotation).
7. Loosen and remove tie rod end to vertical link securing nut (hold ball joint stud to prevent rotation).
8. Disconnect tie rod end from vertical link.
9. Loosen and remove lower wishbone ball joint securing nut (hold ball joint stud to prevent rotation).
10. Disconnect vertical link from lower wishbone.
11. Finally remove securing nut from the upper wishbone ball joint (hold ball joint stud to prevent rotation).
12. *Remove vertical link and front disc shield from the vehicle as an assembly.*
13. Clean components and mating surfaces.
14. Check the condition of the lower ball joint mounting hole in the lower wishbone for damage caused by looseness.
Note:
Check for deterioration of the cone face e.g. pitting, scoring or an elliptical shape.
Note:
If no damage is visible proceed to step 34 (install and align new vertical link to upper wishbone) of this workshop procedure.
15. If the mounting hole is damaged, the lower wishbone will need to be replaced.
On vehicles equipped with 3.0 V6 engines, the generator plastic cover will have to be removed for access if the right hand lower wishbone is
to be replaced and must be reinstalled after completing the alignment check and adjust.
^ Displace and remove generator cover upper fir tree fastener.
^ Loosen and remove generator cover/front under tray securing screw.
^ Loosen and remove generator cover rear securing screw.
^ Remove generator cover.

16. On all vehicles, loosen, remove and discard stabilizer link arm to lower wishbone-securing nut (Illustration 5). (Hold ball joint stud to stop
rotation.)
17. Reposition link arm away from lower wishbone.
18. Loosen and remove front shock absorber to lower wishbone-securing bolt. Discard the nut (Illustration 6).
19. Loosen and remove steering rack securing bolts (Illustration 7). Discard the nut.
20. Displace and reposition steering rack for access.
21. Loosen, remove and discard lower wishbone front and rear securing nuts.
22. Remove and discard lower wishbone front and rear bolts.
Note:
2000 Jaguar S-Type (X200) V6-3.0L Page 51
If cam bolts are already installed, retain them for reuse.
23. Displace and remove lower wishbone.
Note:
When replacing a damaged lower wishbone on a vehicle with the early type front bushings, the lower wishbone on the opposite side must
also be replaced since both sides must have the same style bushings. The later style bushings can be identified by polyurethane inserts in
the forward mounting bushing. Earlier type bushings do not have the polyurethane inserts.
24. Position and align new lower wishbone to no. 1 and No. 2 front beams.
25. Install new wishbone cam bolts if required, as described.
*Caution:
Do not tighten newly installed cam bolts and securing nuts until the alignment check and adjust procedure is performed with the vehicle
lowered, to prevent the wishbone bushes being prestressed during normal operation.*
FRONT CAM BOLT
Install the bolt from the rear, with the cam lobe down (Illustration 8).
Note:
Ensure the cam lobe is fitted centrally between the cam guides on the no. 1 cross-member.
Note:
Fit but do not fully tighten the lock nut, until after the alignment check.
REAR CAM BOLT
Install the bolt from the rear, with the cam lobe down (Illustration 9).
Note:
Ensure the cam lobe is fitted centrally between the cam guides on the no. 2 cross-member.
