Symptom Possible Causes Action


Wheel Fight (Kick Back) - condition
where roughness is felt in the
steering wheel by the driver when
the vehicle is driven over rough
surfaces


Loose or worn steering
components/bushings
CAUTION: DO NOT attempt to adjust the
steering gear yoke. Failure to follow this
instruction will invalidate the steering gear
warranty.

Tighten and install new steering
components/bushings as required
Loose or worn suspension
components/bushings
Tighten and install new suspension
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.

Steering nibble is a rotary oscillation or vibration of the steering wheel, which can be excited at a specific vehicle speed.
Nibble is driven by wheel and tire imbalance exciting a suspension recession mode, which then translates into steering gear
travel and finally steering wheel nibble.

Shudder (Judder)

Shudder is a low frequency oscillation of the entire steering system (tire, wheels, steering gear and linkage, etc.) when the
vehicle is steered during static-park or at low speeds. Shudder is very dependent on road surface.

Torque/Velocity Variation (Phasing/Effort Cycling)

Steering wheel torque variation occurring twice in one revolution is normally as a result of problems with the lower steering
column (intermediate shaft), but foul conditions generally result in either constant stiffness or single point stiffness.
Depending upon the orientation of the joints, the steering can feel asymmetric (torque falling off in one direction and rising in
the other) or else it can simply have pronounced peaks and troughs as the steering moves from lock to lock.

Wheel Fight (Kick Back)

Wheel fight is excess feedback of sudden road forces through the steering system and back to the driver. It is evaluated at all
vehicle speeds over cobblestones, rough roads, and potholes. The tires, wheels, and suspension generate forces into the
steering systems. Steering friction, hydraulic damping, hydraulic compliance, mechanical compliance, steering ratio, and assist
gain all affect how much is transmitted to the driver.

Removal and Installation Published: 04-Jul-2013



CAUTIONS: Removal

Make sure that only the manufacturers' recommended four wheel alignment equipment is used.


Do not turn the steering wheel with the steering column lower shaft disconnected as damage to the clockspring and
steering wheel switches may occur.
NOTES:


Make sure the steering is in the straight ahead position.

installation.

Installation

1. Install the tie rod end, note the number of turns until adjacent to the
locknut.


2. CAUTION: Make sure that the ball joint ball does not rotate.
Connect the tie-rod end ball joint.

Refer to: Wheel and Tire (204-04 Wheels and Tires, Removal and Installation).

Automatic braking is limited to approximately 30% of full pressure (0.3G deceleration) and is intended to provide a
smooth, gradual deceleration in follow mode conditions. Harsh braking by the target vehicle or following the target
vehicle down to very low speeds or to a halt will require driver override of the brakes.
While the radar sensor detects moving and stationary targets for assessment of the environment ahead, the system
does not react to or provide any control in situations other than follow mode conditions. Stationary or slow moving
vehicles (below 10 km/h), pedestrians, objects on the road and oncoming vehicles in the same lane are not recognized.


WARNING: The adaptive speed control system is not a collision warning or avoidance system and that, other than the
limited conditions of follow mode, driver intervention will be necessary to control the vehicle speed.
In follow mode, some situations may cause target ambiguities for the detection system. These situations include:
The nearby presence of a third vehicle when driving on a line slightly offset to the target vehicle.
Vehicles edging into the lane ahead which are not detected by the system until they have moved into the radar beam.

On the approach to, or exit from a bend, a target vehicle may be lost or a new target acquired as vehicles ahead change their
angular position with respect to the radar sensor. On a straight road, if the sensing vehicle is in follow mode below its selected
set speed, losing the target vehicle will cause the sensing vehicle to accelerate to this set speed. This acceleration is
undesirable either on, or entering a bend when the target is suddenly lost, and in this situation the system inhibits the
resumption of the set speed.

The speed control system compares vehicle speed data from the ABS system with the relative speed of an external object as
detected by the radar sensor to ascertain whether the object is stationary or not.


NOTE: If tires are fitted which are different in diameter from those specified for the vehicle, the vehicle speed calculated
by the ABS will not be the true road speed. This situation may cause stationary objects to be falsely identified as moving
vehicles and result in automatic deceleration on a clear road.
