Air Suspension System

The Discovery LR3 LR4 own fully independent air suspension with cross-linking when off-road and the twin-range transfer gearbox with an electronic infinitely variable locking centre differential. As before, a similar locking rear differential is available. The Terrain Response system remains but with two new features – the 'Sand' mode incorporates a new traction control mode to prevent loss of traction when starting off and stopping in soft sand, and the 'Rock Crawl' mode gains a feature that applies gentle brake pressure at low (less than walking pace) speeds to improve grip and stability on slick rock.

Range Rover Sport air suspension system gives the driver the option of three ride height settings including a standard ride height of 172 mm (6.8 in), an off-road height of 227 mm (8.9 in) and a lowered access mode. There is also an extra height available which is accessed by holding the respective button for when the off-road ride height is not enough. When the vehicle bellies out, its control system will sense weight being lessened on the air springs and the ride height is automatically raised to the suspensions greatest articulation. The cross-link aspect of the suspension system, which debuted on the L322 Range Rover in 2002, results in better off-road performance by electronically operating valves in pneumatic lines which link adjacent air springs. In the event of a wheel on one side being raised when travelling off-road, the pneumatic valves are opened and the adjacent wheel is forced down, simulating the action of a live axle setup.

*Removal Guideline

Caution: Damage to the vehicle and air suspension system can be incurred if work is carried out in a manner other than specified in the instructions or in a different sequence.

1.To avoid the possibility of short circuits while working with electric components consult your owner's manual on how to disconnect your battery.

2.Consult your vehicle owner's manual, service manual, or car dealer for the correct jacking points on your vehicle and for additional care, safety and maintenance instructions. Under no circumstances should any work be completed underneath the vehicle if it is not adequately supported, as serious injuries and death can occur.

1.Remove rear wheel to expose the rear air strut.(picture 1)

2.Loosen and remove the lower mount nut. Support the air strut and remove the lower mount bolt.(pictures 2,3)

3.Loosen and remove the three(3)top mounting nuts.(picture 4)

4.Carefully lower the air strut to gain access to the air line. Unthread the air fitting.(picture 5)

5.Remove the air strut from the vehicle.(picture 6)

6.Remove the air line fitting from the air hose and discard. To remove the air line fitting,remove the collet and the remaining fitting will slide off of air hose.(picture 7)

7.Removal complete.

*Installation Guideline

1.Place new air strut onto vehicle, oriented in the same position as strut previously removed.

2.Insert the air line into the voss fitting, making sure it is firmly seated and will not pull back out.(picture 8)

3.Install and tighten the three(3)top mounting nuts to manufacturer's specification.(picture 9)

4.Support the air strut and install the lower mount bolt. Re-install and tighten the lower mount nut to manufacturer's specification.(pictures 10,11)

5.Re-install the rear wheel and tighten lug nuts to manufacturer's specification.Installation complete.

*Warning & Notice

Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury.

Any air spring which is unfolded must be refolded prior to being installed in a vehicle. Refer to the procedure. An incorrectly folded air spring could rupture, altering the handling characteristics of the vehicle. If a vehicle has been driven with an incorrectly folded air spring, a new air spring must be installed. Failure to follow these instructions may result in serious injury to vehicle occupant(s).

Failure to observe the following instructions may result in a sudden failure of the air spring or suspension system.

Any rear spring which is unfolded must be refolded prior to being installed in a vehicle.

The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position.

Incorrectly folded air springs found on vehicles during pre-delivery inspection or after use must be installed new.

Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop.

When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using the air spring fill procedure.

After inflating an air spring in the hanging position, it must be inspected for correct shape.

Note

The vehicle must be positioned on a suitable lifting device prior to deflating the air suspension system.

With the vehicle in NEUTRAL, position on a hoist until the wheel and tire assemblies are slightly above the ground.

2.Using the scan tool, vent the air springs.

3.Remove the air spring retainer.

4.Detach the air spring from the rear axle.

5.Remove the air spring in the following sequence.

1.Disconnect the air spring solenoid electrical connector.

2.Compress the quick connect locking ring and pull out the air tube.

3.Remove the air spring.

Please double confirm the compatibility chart as well as the OEM number before purchasing.

Instruction is not included. Professional installation is recommended.

Frequently Asked Questions

How to prevent the damage of air springs/How to extend the service life of air springs/struts etc.?

An air strut with separable air springs

If your vehicle offers a separable air suspension (Audi Allroad A6 C5, Mercedes-Benz W164, BMW X5, etc.), you should regularly (about once a week) lift the car to the maximum position, and remove dirt with a high-pressure cleaner (keep the cleaner at a distance to the air spring about 30 cm/12 inches, otherwise water pressure can damage the air spring). The highest position may vary depending on your model and regulation options. Therefore, please test this by trying the different modes available to you (Sport, comfort, dynamic, off-road) and choose the one that sets your vehicle to the highest position. The dirt will most likely be found under the fold of the pneumatic chambers. If you find a frozen layer of bitumen on the piston guide (the part of a strut on which the air spring is installed), it is recommended to clean it as well. Whenever possible, avoid riding on fresh asphalt, as fresh bitumen mixed with sand immediately results in a build-up of abrasives on the piston and in turn contributes to accelerated wear and tear of the air spring.

A complete air suspension shock

Many cars such as Mercedes W220 or W211 are set up with a complete air strut - shock absorber and air spring visually form a complete spare part. In many cases, you can easily recognize these by the metal cups with which the air spring is tightly mounted. To best avoid any damage, we highly recommend to regularly check the condition of the dust protection seals of the air strut.

What is the difference between an air spring and an air strut?

The air spring is a part of the air strut. Some vehicles (e.g. Mercedes ML) allow you to change the air spring separately. At our online shop you have the opportunity to buy either the whole air strut or only the air spring. For some type of vehicles it is not possible to change the air spring separately. In this case the whole air strut should be replaced.

Which side of my car is the Right and Left?

The right and left sides of an automobile are determined as if sitting in the car facing forward. Thus, the left side is on the left when sitting in the car facing forward, and the right side is on the right. For American cars, the driver’s side is on the left, and the passenger sits to the right of the driver. For cars in Japan, Britain, Ireland, the Bahamas and some other former British colonies -- where they drive on the left side of the road -- the passenger sits on the left side, and the driver (along with all the driving controls) is on the right.
