Date: 03 August 2007
Model:
S-TYPE
VERSION 2 OF THIS BULLETIN PROVIDES CORRECTED PART NUMBER INFORMATION. CHANGES ARE HIGHLIGHTED.
SECTION: 205-00
Whine from Rear of Vehicle
AFFECTED VEHICLE RANGE:
S-TYPE VIN: M45255-N83621
  Page 242
Model Year: 2003 to 2008
CONDITION SUMMARY:
HARMONIC VIBRATIONS GENERATE WHINE FROM REAR OF VEHICLE
Situation:
A customer may express concerns of a whine from the rear of the vehicle at 96 km/h (60 mph). A harmonic frequency generated by the rear
differential (axle) may be the cause.
Action:
Should a customer concern be verified, refer to the Repair Procedure detailed in this bulletin to determine if a new drive shaft, new axle housing
bushing or a new differential (axle) assembly is required to complete the necessary service fix.
PARTS
WARRANTY:
NOTE:
Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only.
Always refer to DDW to obtain the latest repair time.
DDW requires the use of causal part numbers. Labor only claims must show the causal part number with a quantity of zero.
REPAIR PROCEDURE
UPDATE DRIVELINE TO LATEST SPECIFICATION
NOTE:
It is important to perform research on previous repairs and to inspect vehicle driveline components to verify the current condition of the
vehicle.

NOTE:
The latest level driveshaft can be identified by a diameter reduction in the tube ([B] Figure 1) approximately 150 mm (6 inches) from the
rubber coupling at the differential end of the shaft. Earlier configuration parts have a straight rear tube. ([A] Figure 1)
1. Inspect to determine if the vehicle has a new configuration driveshaft installed. ([B] in Figure 1)
NOTE:
Global Technical Reference (GTR) lookup sequence is as follows:
GTR Home > NAS > X200 S-TYPE / Service Information/ 2006 > Workshop Manuals > Bookmark "Chassis/Driveline/205-01 Drive
Shaft" LINK "Removal and Installation Driveshaft (47.15.01)"
2. If the old style drive shaft is installed ([A] in Figure 1), refer to GTR Workshop Manual, section 205-01 (47.15.01) and install a new
configuration driveshaft.
3. Re-evaluate the vehicle to determine if further action is required.
4. If the vibration remains and the vehicle has previously had a new differential installed, check to verify that the modified bushing (black top) is
installed.
NOTE:
Global Technical Reference (GTR) lookup sequence is as follows:
GTR Home > NAS > X200 S-TYPE / Service Information/ 2006 > Workshop Manuals > Bookmark "Chassis/Driveline/205-02 Rear
Drive Axle/Differential" LINKS "Removal and Installation Axle Assembly (51.25.13)" and "Axle Housing Bushing (64.25.30)"
5. If the new bushing is not installed, perform the following:
^ Refer to GTR Section 51.25.13 and remove the Axle.
^ Refer to GTR Section 64.25.30 and install a new rear axle housing bushing.
^ Re-install the Axle.
6. Test the vehicle.
7. If the whine is still prefer to GTR and install a new differential insuring it contains the new style "black" bushing.
