Upper Control Arm
The forged-aluminum upper control arm is a wishbone design and connects to the vehicle body through two plain bushes, and
links to the swan neck wheel knuckle by an integral ball joint. The upper control arm is inclined to provide anti-dive
characteristics under heavy braking, while also controlling geometry for vehicle straight-line stability.
Lower Control Arm
The forged aluminum lower control arms are of the wishbone design; the arms separate to allow for optimum bush tuning:
The rear lateral control arm is fitted with a bush at its inner end which locates between brackets on the subframe. The
arm is secured with an eccentric bolt which provides the adjustment of the suspension camber geometry. The outer end
of the control arm has a tapered hole which locates on a ball joint fitted to the wheel knuckle. An integral clevis bracket
on the forward face of the lateral control arm allows for the attachment of the forward control arm. A bush is fitted
below the clevis bracket to provide for the attachment of the stabilizer bar link. A cross-axis joint is fitted to a
cross-hole in the control arm to provide the location for the clevis attachment of the spring and damper assembly.
The forward control arm is fitted with a fluid-block rubber bush at its inner end which locates between brackets on the
subframe. The arm is secured with an eccentric bolt which provides adjustment of the castor and camber geometry. The
outer end of the control arm is fitted with a cross-axis joint and locates in the integral clevis bracket on the lateral
control arm.
Wheel Knuckle
The cast aluminum wheel knuckle is a swan neck design and attaches to the upper control arm and lower lateral control arm.
The lower lateral control arm locates on a non serviceable ball-joint integral with the wheel knuckle. The lower boss on the
rear of the knuckle provides for the attachment of the steering gear tie-rod ball joint.
The wheel knuckle also provides the mounting locations for the:
wheel hub and bearing assembly
the wheel speed sensor (integral to the wheel hub and bearing assembly)
brake caliper and disc shield.
Stabilizer Bar
The stabilizer bar is attached to the front of the subframe with bushes and mounting brackets. The pressed steel mounting
brackets locate over the bushes and are attached to the cross member with bolts screwed into threaded locations in the
subframe. The stabilizer bar has crimped, 'anti-shuffle' collars pressed in position on the inside edges of the bushes. The
collars prevent sideways movement of the stabilizer bar.
The stabilizer bar is manufactured from 32mm diameter tubular steel on supercharged models and 31mm diameter tubular
steel on diesel and normally aspirated models and has been designed to provide particular characteristics in maintaining roll
rates, specifically in primary ride comfort.
Each end of the stabilizer bar curves rearwards to attach to a ball joint on a stabilizer link. Each stabilizer link is secured to a
bush in the lower lateral arm with a bolt and locknut. The links allow the stabilizer bar to move with the wheel travel providing
maximum effectiveness.
The only difference between the front stabilizer bars, in addition to the diameter, is in the shape to accommodate engine
variant:
a slightly curved bar, between bush centers, for V6 diesel (31 mm dia) and V8 gasoline supercharged (32 mm dia),
a straight bar, between bush centers, for V6 and V8 normally aspirated gasoline engines (31 mm dia).
Spring and Damper Assembly
The spring and damper assemblies are located between the lower lateral arm and the front suspension housing in the inner
wing. Dependant on vehicle model there are three types of coil spring and damper available:
a standard oil passive damper (All models except supercharged),
an adaptive damper, also known as Computer Active Technology Suspension (CATS) on 4.2L supercharged vehicles up to
2010MY, For additional information refer to Vehicle Dynamic Suspension 4.2L.
a continuously variable adaptive damper, also known as Adaptive Dynamics System on 5.0L supercharged vehicles from
2010MY. For additional information refer to Vehicle Dynamic Suspension 5.0L.
The dampers are a monotube design with a spring seat secured by a circlip onto the damper tube. The damper's lower
spherical joint is an integral part of the lateral lower control-arm, and the damper takes the form of a clevis-end, which
straddles the spherical joint.
The damper piston is connected to a damper rod which is sealed at its exit point from the damper body. The threaded outer
end of the damper rod locates through a hole in the top mount. A self locking nut secures the top mount to the damper rod.
The damper rod on the adaptive damper has an electrical connector on the outer end of the damper rod.
Supercharged 4.2L vehicles up to 2010MY: The adaptive damper functions by restricting the flow of hydraulic fluid through
internal galleries in the damper's piston. The adaptive damper has a solenoid operated valve, which when switched allows a
greater flow of hydraulic fluid through the damper's piston. This provides a softer damping characteristic from the damper. The
adaptive damper defaults to a firmer setting when not activated. The solenoid is computer controlled and can switch between
soft and hard damping settings depending on road wheel inputs and vehicle speed.
Supercharged 5.0L vehicles from 2010MY: The variable damper functions by adjustment of a solenoid operated variable orifice,
which opens up an alternative path for oil flow within the damper. When de-energized the bypass is closed and all the oil flows

the aluminum wheel knuckle via an integral ball-joint.
Lower Control Arm
The aluminum lower arm locates to the subframe via one cross-axis joint and one plain rubber bush, and to the wheel knuckle
via a second plain rubber bush.
The rear of the control arm has mounting points for the damper and the stabilizer link.
Toe-Link
The toe-link is located between the wheel knuckle and brackets on the subframe.
The toe-link comprises an inner rod with integral axial ball joint. The inner ball joint has a threaded spigot which locates in a
bracket on the subframe and is secured with a locknut. The rod has an internal thread which accepts the outer rod.
The outer rod has a cross-axis joint at its outer end which is located in a clevis on the wheel knuckle, and is secured with a
bolt and locknut.
The length of the toe-link can be adjusted by rotating the inner rod. This allows for adjustment of the toe angle for the rear
wheel. Once set the inner rod can be locked in position by tightening a locknut on the outer rod against the inner rod.
Wheel Knuckle
The cast aluminum wheel knuckle attaches to:
the upper control arm via a ball-joint located in the arm,
the lower control arm via a plain rubber bush located in the arm,
the toe-link via a cross-axis joint located in the toe link.
The wheel knuckle also provides the mounting locations for the:
wheel hub assembly,
wheel bearing,
wheel speed sensor,
brake caliper,
and disc shield.
Stabilizer Bar
The solid construction stabilizer bar and bushes have been designed to provide particular characteristics in maintaining roll
rates, specifically in primary ride comfort. There are six derivatives of rear stabilizer bar, with different diameters, to support
the various powertrains:
V6 gasoline - 12.7 mm solid bar
V8 4.2L and 5.0L gasoline - 13.6 mm solid bar
V6 2.7L diesel -14.5 mm solid bar
V6 3.0L diesel - 14.5 mm solid bar
V6 3.0L diesel with Adaptive Damping – 16mm tubular
V8 4.2L gasoline supercharged – 16mm tubular
V8 5.0L gasoline supercharged
- SV8 - 17mm tubular
- XFR - 18mm tubular
The stabilizer bar is attached to the top of the subframe with two bushes and mounting brackets. The stabilizer bar has
crimped, 'anti-shuffle' collars pressed in position on the inside edges of the bushes. The collars prevent sideways movement of
the stabilizer bar.
Each end of the stabilizer bar curves rearward to attach to a ball joint on each stabilizer link. Each link is attached via a
second ball joint to a cast bracket on the lower control arm. The links allow the stabilizer bar to move with the wheel travel
providing maximum effectiveness.
Spring and Damper Assembly
The spring and damper assembly are attached to cast brackets on the lower control arms and to the vehicle body by four studs
secured by locking nuts. Dependant on vehicle model there are three types of coil spring and damper available:
a standard oil passive damper (All models except supercharged),
an adaptive damper, also known as Computer Active Technology Suspension (CATS) on 4.2L supercharged vehicles up to
2010MY, For additional information refer to Vehicle Dynamic Suspension 4.2L.
a continuously variable adaptive damper, also known as Adaptive Dynamics System on 5.0L supercharged vehicles from
2010MY. For additional information refer to Vehicle Dynamic Suspension 5.0L.
The dampers are a monotube design with a spring located by a circlip onto the damper tube. The lower end of the damper has
a spherical joint which locates in the lower control arm and is secured with a bolt.
The damper piston is connected to a damper rod which is sealed at its exit point from the damper body. The threaded outer
end of the damper rod locates through a hole in the top mount. A self locking nut secures the top mount to the damper rod.
The damper rod on the adaptive damper has an electrical connector on the outer end of the damper rod. www.JagDocs.com

Wheels and Tires - Wheels and Tires - Overview
Description and Operation
OVERVIEW Published: 25-May-2012
A number of alloy wheel designs are available ranging from 17 to 20 inch in diameter. A Tire Pressure Monitoring System
(TPMS) is used to monitor the air pressure in each tire and inform the driver if the pressure falls below predetermined
thresholds.
All wheels are of cast construction in aluminum alloy with the choice of wheel design dependant on the vehicle trim level and
engine derivative.
On normally aspirated petrol models and all diesel models a 4J X 18 inch temporary spare wheel is supplied as standard,
supercharged petrol models are supplied with a 4Jx19 inch temporary spare wheel. In some major European markets an Instant
Mobility System is offered as an alternative to the spare wheel. The Instant Mobility System is capable of providing a
temporary repair and tire inflation to a puncture of up to 6mm in diameter in the tread area of the tire. A puncture in the tire
wall cannot be repaired using the system.
The vehicle jack and accessories are stored in the spare wheel-well in the luggage compartment.
Tire Changing
WARNINGS:
Tires must be inflated to the recommended pressures when the tires are cold (ambient temperature) only. Refer to label
on the 'B' pillar for recommended tire pressures. If the tires have been subjected to use or exposed to direct sunlight, move
the vehicle into a shaded position and allow the tires to cool before checking or adjusting the pressures.
Valve stem seal, washer nut, valve core and cap should be replaced at every tire change. Valve stem seal, washer and
nut must be replaced if the valve retention nut is loosened. Sensor units and nuts must be fitted using correct torque figures
and associated profile. Damage to the vehicle and consequently injury to the vehicle's occupants may result if these
instructions are not adhered to.
NOTE: The TPMS valve should be serviced using the suitable service kit, each time the tyre is dismounted, to ensure an
air tight seal. Attention should be made to the detail of fitting this kit.
Vehicles fitted with TPMS can be visually identified by an external metal locknut and valve of the tire pressure sensor on the
road wheels. Vehicles without TPMS will have rubber tire valve.

1 Tire valve and pressure sensor 2 Tire fitting/removal tool initial start position 3 High tire and bead tension area 4 Low tire and bead tension area When removing the tire, the bead breaker must not be used within 90 degrees of the tire valve in each direction on each side
of the tire.
When using the tire removal machine, the fitting arm start position must be positioned as shown in the tire changing
illustration for each side of the tire. The wheel can then be rotated through 180 degrees in a counter-clockwise direction. This
will relieve tension from the tire bead allowing the remaining 180 degrees of the tire to be manually pulled from the rim.
When refitting the tire, position the fitting arm as shown. Rotate the tire and take care that the bead on the low tension side
of the tire does not damage the sensor.
Run-Flat Tires
Run-flat tires are not available on vehicles from 2011MY.
TREAD Act - NAS Only
Vehicles supplied to the North American markets must comply with the legislation of the Transport Recall Enhancement,
Accountability and Documentation (TREAD) act. Part of the requirement of the TREAD act is for the vehicle to display a label
which defines the recommended tire inflation pressure, load limits and maximum load of passengers and luggage weight the
vehicle can safely carry. This label will be specific to each individual vehicle and will be installed on the production line. The
label is positioned on the driver's side 'B' pillar on NAS vehicles and the inside rear face of the LH door on Canadian
specification vehicles.
This label must not be removed from the vehicle. The label information will only define the specification of the vehicle as it
came off the production line. It will not include dealer or owner fitted accessory wheels and tires of differing size from the
original fitment.
If the label is damaged or removed for body repair, it must be replaced with a new label specific to that vehicle. A new label is
requested from Jaguar parts and will be printed specifically for the supplied VIN of the vehicle.
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitoring System (TPMS) is a driver assistance system which assists the driver to maintain the tire
pressures at the optimum level. TPMS is standard fitment on NAS vehicles and an optional fitment in other markets. TPMS
