Clunk

Clunk is a metallic noise heard when the automatic transmission is engaged in REVERSE or DRIVE. The noise may also occur
when the throttle is applied or released. Clunk is caused by transmission calibration, backlash in the driveline or loose
suspension components and is felt or heard in the vicinity of the rear drive axle.

Bearing Rumble

Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a worn/damaged wheel bearing. The
lower pitch is because the wheel bearing turns at only about one-third of the driveshaft speed. Wheel bearing noise also may
be high-pitched, similar to gear noise, but will be evident in all four driving modes.

a narrow vehicle speed range.

If the concern becomes evident during this check, verify it fits the description given before the road test. If the concern is not
evident, attempt to duplicate the condition using the information from the description.

If a concern exists, use the Symptom Chart in order to isolate it to a specific sub-system and condition description. From this
description, a list of possible sources can be used to further narrow the cause to a specific component or condition.

components/bushings as required

Nibble (Shimmy) - condition where
oscillation of the steering wheel
occurs (not vertical which is Shake).
This is driven by road wheel
imbalance

Road wheel and tire
condition
Check for wheel and tire damage. Install
new components as required
Check for tire uniformity. Install new
tire(s) as required
Road wheel imbalance
Check and adjust road wheel balance as
required
Shake - condition where vertical
vibration of the steering
wheel/column occurs (not
oscillation which is Nibble)
NOTE: Vibration smooths out
after several miles of driving

Road wheel imbalance due
to tire flat-spotting
Ensure tires installed are to Jaguar
specification. Install new tires as
required
Check and adjust tire pressures to
correct specification Component Tests

Steering Linkage Inspection and Backlash (Free play) Check


CAUTION: Steering gear boots must be handled carefully to avoid damage. Use new clamps when installing steering gear
boots.

Inspect the boots for cuts, deterioration, twisting or distortion. Check the steering gear boots to make sure they are tight.
Install new boots or clamps as required.


NOTE: The following steps must be carried out with assistance.

1. With the wheels in the straight ahead position, gently turn the steering wheel to the left and the right to check for free
play.
