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
