Air Springs

The air springs work on the same principle but the front and rear components differ in construction:

• the front units are integral with damper
• the rear units are separate from the damper.

The air springs are manufactured from a flexible rubber and 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 rolls onto the air spring's piston, compressing the air inside. 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 front or rear valve block.

Replacement of an individual air spring does not require a full depressurization of the air suspension system. Only the corner concerned need be depressurized. This is achieved using routines in the Land Rover approved diagnostic system.

When servicing of an air spring or a full system depressurization is required, the weight of the vehicle must be supported before the system is depressurized. On reassembly, the pipes between air springs and the valve blocks must be must be connected at both ends before the weight of the vehicle is applied to the air springs. Rear air springs must also be pressurized before the weight of the vehicle is applied to them.
