Issue: Jaguar XJ customers may complain of a creak, squeak or knock from the front
suspension area, particularly enhanced at various speeds whilst travelling over speed
bumps or uneven road surfaces. Upon inspection, technicians have identified the causal
part as being the front anti- roll bar (ARB) bushes, having the P/N C2D5793.
Replacement with a new pair of bushes has subsequently resolved the customer
complaint.
Investigations into returned parts by both JLR and component suppliers have failed to
identify causal factors or defects which may have created the initial customer complaint.
Cause: The noise observed may originate from the interaction of the components within
the front ARB assembly, rather than being solely from the bushes. Dis-assembly of the
components may, in some cases, remove the noise condition.
Action: Firstly, please get confirmation through the vehicle history file that an original
bush is still fitted to the vehicle. If that is the case, and should a technician receive a
customer complaint as outlined above, please follow the steps as listed below;
1) Record a sound file (preferably in WAV format) using a mobile phone, with
assistance of a passenger
2) Answer the following questions, regarding the noise input:
Is it when the vehicle is in stationary or when moving?
Is there any input to the steering wheel? Do you turn the steering wheel?
Is the noise a single event (heard once) or heard more than once?
Is the noise evident just in a straight line condition or just when cornering?
Is the noise evident when the vehicle is driven over road bumps?
Is the noise evident when you apply the brakes or the throttle?
Describe what speed the noise is evident?
Is the noise evident first time in the morning?
3) Remove the complete assembly of the front anti-roll bar, clamps and bushes as one
complete unit, with care taken to ensure the system remains as undisturbed as
possible.
