2010-2012 Range Rover L322 Chassis with VDS 4 Wheel Air Suspension Conversion Kit With Warning Light Module (LB54BM)

Replaced Components
The 2010-2012 Range Rover L322 Chassis is built with the following suspension components:
2010-2012 Range Rover L322 Chassis Air Struts (x4)- struts that contain a rubber air bladder (spring) whose capabilities are managed by an electronic suspension control module. The strut portion reduces vibration and bounciness caused by driving on rough surfaces. The rubber air springs inflate to help maintain the vehicle's correct ride height.
2010-2012 Range Rover L322 Chassis 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, and like all moving parts, they will eventually wear out.
2010-2012 Range Rover L322 Chassis Air Lines- tubes that carry pressurized air from a compressor to the rubber air springs atop the air struts in order to adjust the height of the vehicle, respectively.
2010-2012 Range Rover L322 Chassis Compressor- creates and sends pressurized air to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time 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 air struts and air springs and installing them, only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.
2010-2012 Range Rover L322 Chassis Dryer Assembly- used to keep moisture out of air lines and air springs in order 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 in order to eliminate the moisture and prevent any further damage.
2010-2012 Range Rover L322 Chassis Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.
2010-2012 Range Rover L322 Chassis 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
Early detection of a failed or leaking components is the key to avoiding total failure of the 2010-2012 Range Rover L322 Chassis air suspension system. Look for these classic signs to help you determine if this is occurring. First, check the ride height on your Rover. Are there any sudden and very noticeable changes? A drop of three to five inches of ride height is common. Do you see sagging on one side while the other is inflated? Does the rear or front of the vehicle look like it‚ squatting down on the ground? If your suspension is failed or leaking, your air compressor will cease working or be overworked. Lastly, check your instrument cluster. Is there a suspension warning light illuminated? If any of these apply to your vehicle, there is a good chance you will need a replacement or repair.

OEM Replacement Cost

• Air Struts ($396/strut)
• Compressor Assembly ($720/compressor)
• = TOTAL: Over $2,300 (and that doesn't even include replacing electronic components that are known to fail such as the height sensors).
