Vibration Felt Through Steering Wheel or Seats - Wheels/Tires - Diagnostic Procedure

Remove and destroy Bulletin S204-07, dated 04/01.

Replace with this Bulletin.

Revisions are marked with bold text in the illustration.

Issue:

In the event of customer complaints of a vibration through the steering wheel and/or the seat, a procedure can be followed in order to rectify the

concern.

Action:

If a customer complaint is received and the wheels and tires are suspected, the following workshop procedure must be followed to assist in the

rectification of the concern.

WORKSHOP PROCEDURE

1. Prior to any rectification work, the vehicle must be inspected for any damage to the wheels and tires.

2. Check the tire pressures and visually inspect the suspension components for tightness.

3. Drive the vehicle for a distance of 24-32 Km (15-20 miles, approximately) at a speed of 80 Km/h (50 mph) to warm the tires and eliminate the

possibility of incorrect diagnosis due to flat spotting of the tires.

Note:

This procedure needs to be carried out prior to any analysis work being undertaken. Driving the vehicle as recommended will work out any

temporary flat spotting that may have occurred in the tires, especially if the vehicle has been parked for an extended period of time.

4. Once the tires are heated, the WDS Vehicle Vibration Analyzer (VVA) procedure must be carried out to determine the possible source of

vibration.

Note:

In the first instance the VVA sensor should be mounted on the seat rail in the X-axis (fore/aft) orientation. If there is no reading in the X-axis

orientation, repeat test in the Y-axis (left/right) and Z-axis (up/down) or until a reading is obtained (Illustration 1).

5. On completion of the road test, return the vehicle to the workshop and raise from the floor immediately to prevent the inducement of any flat

spotting of the tires.

6. If the balance of the wheel and tire is suspect, check/adjust the wheel and tire balance. Excellent results have been obtained when using a tire

balancer with road force variation measuring capability. Refer to Technical Bulletin S204-09.

Note:

Only the balance weights of the "two piece" or "stick on" variety (Jaguar specification only) should be used. No claims will be accepted where

knock on weights have been used, and may result in debit action being undertaken.

FURTHER INFORMATION

If a vibration is still present up to the speed of 130 Km/h (80 mph) then the replacement of the front suspension forward mounting bush may need to

be carried out. (See workshop manual - JTIS CD ROM, section 204-01, SRO 60.35.45).

Note:

The replacement of this bush is only allowed after all other avenues have been explored and may be subject to warranty audit. This procedure is

only valid on vehicles prior to VIN L77700. Some of these vehicles may have already received the latest bushing as a result of Recall R-136.

Note:

If a vibration is still present, call the Technical Hotline at 1-888-524-3577 for further guidance. Prior to the call, the Technical Hotline Precall

Work Sheet (S-88, available on the Service and Warranty Forms CD-ROM) must be filled in along with the report form (the VVA results must

be at hand ready to fax.
