DESCRIPTION AND OPERATION
REAR SUSPENSION
Description
The rear suspension design locates the rear axle with
two lightweight composite radius arms (1) and a
Panhard rod (2). The system allows maximum axle
articulation and wheel travel while maintaining roll
stiffness, directional stability and vehicle refinement.
The composite radius arm is mounted to the chassis
through a ferrule rubber bush and to the axle using a
’sealed for life’ isolation rubber.
The vehicle height sensors are also linked to the
radius arms; for full details of the height settings.
See
FRONT SUSPENSION, Description and operation.
The panhard rod is mounted to the chassis through
ferrule rubber bushes as shown in 64M7005.

DESCRIPTION AND OPERATION
Conventional telescopic shock absorbers (3) used to
control body movement, are secured to the chassis
cross frame and a fabricated lower mounting, welded
to the axle, that also supports the radius arms. The
upper fixing comprises a single bolt passing through a
ferrule rubber bush. The lower fixing of the shock
absorber comprises of a stem type mount with two
rubber bushes and support washers, secured to the
axle mounting with a single retaining nut.
Cellular foam bump stops (4) are fitted under the
chassis adjacent to the air springs and prevent any
possible damage that could occur should there be
excessive axle to chassis movement. Should there be
a loss of air pressure in the air springs (5) the vehicle
can still be driven safely, at a speed not exceeding
35mph (56 km/h), with the bump stops resting on the
axle, although this will result in a hard ride. The loss of
air pressure should be investigated as soon as
possible. ’Progressive’ bump stops are used and will
reform from a compressed state when the load is
released.
