The air springs on the front and rear suspension are similar in construction. The air springs are manufactured from a
flexible rubber. Each air spring forms an air tight cavity which provides the required spring rate for each corner of the
vehicle.
As the air spring is compressed, the rubber material compresses and rolls down the side of the vertical housing below
the spring. An air connection port is located on the top of each spring and allows air to be added or removed from
each spring. The port is connected via a Voss connector and a plastic tube to the valve block on the reservoir.
Replacement of an individual air spring does not require a full depressurisation of the air suspension system. Only the
corner concerned need be depressurised.
When servicing of an air spring or a full system depressurisation is required, the weight of the vehicle must be
supported before the system is depressurised. On reassembly, the air spring must be fully pressurised before the
weight of the vehicle is applied to it.
Air Pipes
The system is interconnected via yellow and black nylon pipes. The yellow pipes denote RH side and the black pipes
denote LH side. The pipes are attached to the subframes and vehicle body with clips. To ensure that the correct
routing is maintained, the pipes have timing marks which align with various clip positions. The timing marks are in the
form of a white band around the pipe, indicating the clip position. If the correct routing is not achieved, unnecessary
tension at the pipe joints will occur resulting in possible early failure.
