Replaced Components

The 1999-2004 Discovery II is built with the following suspension components:

1999-2004 Discovery II Shock Absorbers (x4) - a metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.

1999-2004 Discovery II Air Struts (x4) - struts that contain an air bladder whose dampening capabilities is controlled by the suspension control module; these have two functions. They connect the wheel of a vehicle to the driving surface to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. They also help maintain the vehicles correct ride height, especially whenever the amount of load put onto the vehicle changes.

1999-2004 Discovery II Height Sensors (x4) - a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part; like all moving parts, it will eventually wear out.

1999-2004 Discovery II Air Lines - tubes that run from a compressor (air suspension) to the air struts, which carry pressurized air to the air bags components to adjust the height of the vehicle, respectively.

1999-2004 Discovery II Solenoids (x4) - usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out, causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive workload will eventually lead to total failure of the compressor.

1999-2004 Discovery II Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump works harder to keep the system inflated. When air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.

1999-2004 Discovery II Dryer Assembly - used to keep moisture out of air lines and air springs to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced to eliminate the moisture and prevent any further damage.

1999-2004 Discovery II Suspension Control Module - a computer that is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.

1999-2004 Discovery II O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.

Suspension Failure Signs
If the 1999-2004 Discovery II cannot reach and maintain its proper ride height, it may have a failed or leaking air suspension system. Early diagnosis of a bad suspension is the key to avoiding total failure. Look for a sudden uneven height difference between different sides of the Discovery. A sagging rear end with an inflated front end is typically seen. This gives the illusion the Discovery is squatting down in the rear. There may also be a shifting lean from one side to the other. Any of these height variances can wear out the air compressor. If the air compressor has already stopped working, a suspension warning light may be illuminated on the dashboard. When this occurs, suspension failure is advanced. The Discovery owner should get any suspension issue fixed immediately; the longer one waits, the more expensive a repair will be.
