OVERVIEW
The rear suspension features long travel McPherson struts to optimize on and off road performance.
The suspension components are mounted on a subframe which provides a rigid platform attached to the underside of the
vehicle body. The subframe is mounted to the body on 4 bushes which have differing compression rates to absorb lateral
and longitudinal loading from cornering and braking.

Damper piston rod
The spring and damper assembly is a twin tube design with the conventional coil spring located on a welded spring seat on
the damper tube. The lower end of the damper body locates in the wheel knuckle which is clamped with a bolt.
The damper functions by restricting the flow of hydraulic fluid through internal galleries within the damper. The damper rod
moves axially within the damper, its movement limited by the flow of fluid through the galleries, providing damping of
undulations in the terrain. The damper rod is sealed at its exit point from the damper body to maintain the fluid within the
unit and to prevent the ingress of dirt and moisture. The seal also incorporates a wiper to keep the rod clean.
The damper rod is located through a central hole in the top mount assembly. The rod is threaded at its outer end. A
self-locking nut secures the top mount to the damper rod. A spring aid is fitted to the damper rod to prevent the top
mount contacting the top of the damper during full suspension compression and also assists the suspension tune. A boot
is fitted between the damper body and the top mount and protects the damper piston rod from damage.
The coil spring fitted differs with vehicle specification. Each spring is colour coded to identify its rating and fitment
requirements.
The coil spring is located in a spring seat which is an integral part of the damper body and contains a spring isolator. The
design of the spring seat prevents the spring rotating. The spring has a linear rate compression and is inclined to counter
cornering forces. The opposite end of the coil spring is also located in a spring isolator which is fitted in the top mount
assembly. Both spring isolators are made from rubber and prevent any noise produced during damper and spring
compression/extension from being transmitted to the vehicle body. A mass damper is attached to the damper spring seat
to absorb vibration and prevent noise intrusion into the vehicle interior.
The top mount is fitted with a gasket to prevent the ingress of moisture between the top mount and the turret mounting.
The top mount attaches to a strengthened turret on the chassis with 3 integral studs and self-locking nuts.
Two brackets are welded to the damper body. One bracket provides for the attachment of the stabilizer link. The second
bracket provides for the attachment of the brake hose and wheel speed sensor cable. This bracket also positively locates
the damper into the wheel knuckle and its location is critical to controlling the vehicle trim height.

Lateral wheel location is provided by 2 transverse links which are located between the subframe and the wheel knuckle.
The links are long to give excellent camber control. Each link is fitted with dynamic bushes to control the rear camber in a
progressive manner as cornering loads increase which gives a limited amount of passive rear wheel steering. The 2
transverse links are different in their design. The front link is a steel pressing. The rear link is fabricated from squeezed
and cropped tube. The links are designed to withstand vehicle jacking loads.
The front transverse link is fitted with bushes which compress under cornering forces to provide a controlled amount of rear
wheel toe-in, in addition to the camber control. The front link has a deform point in a central position along its length.
This allows the link to be deformed in the event of a severe lateral rear wheel impact, for example striking a kerb. In the
event of a severe lateral impact, the link will permanently deform, absorbing the impact and protecting the subframe from
damage. The amount of deformation creates excessive toe-in which is immediately noticeable to the driver.
The rear transverse link is mounted to the subframe using an eccentric bolt and washer which allows for adjustment of the
wheel toe angle.
Both transverse links are attached to the subframe with bolts and locknuts. The outer ends of each link locate in mounting
holes integral with the wheel knuckle and are secured with bolts and locknuts.
