Replaced Components

The 1990-2000 Lexus LS 400 is built with the following suspension components:

1990-2000 Lexus LS 400 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 in order 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.

1990-2000 Lexus LS 400 Height Sensors (x2)- 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.

1990-2000 Lexus LS 400 Compressor- This vehicle is equipped with one air suspension compressor. The compressor is responsible for pumping up the air springs and shocks. When the air suspension starts leaking, the compressor is forced to run continuously to try and keep the air springs inflated. After a couple of days of running non-stop, the compressor will burn itself out. Replacing the compressor is a timely and expensive project to undertake.

1990-2000 Lexus LS 400 Dryer Assembly- This vehicle is equipped with a dryer assembly. The dryer assembly is responsible for getting moisture out of the air lines. Once the air suspension parts start to leak, moisture will build up throughout the air system. Moisture damages the air suspension components from the inside out. The dryer must be replaced whenever the compressor is replaced to prevent further damage.

1990-2000 Lexus LS 400 Suspension Control Module- This vehicle is equipped with a suspension control module. This module is the brain of the suspension system and it reads all of the signals that are being sent by the height sensors and determines if the vehicle needs to be raised or lowered.

1990-2000 Lexus LS 400 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

The more you know about failed suspension, the easier it will be for you to diagnose your bad or leaking system. First, check your ride height. Take note of any sagging or inflated areas. Ride height should remain consistently even, or else you’ve got a problem. Check other vehicle parts for wear out- the air compressor frequently quits working when a bad suspension is at fault. Look for a suspension warning light on the instrument board. Any of these signs means you need to get your system fixed, stat!



OEM Replacement Cost

+ Air Strut ($799/strut)
+ Compressor and Dryer Assembly ($435)
= TOTAL: Over $3,630 (and that doesn't even include replacing electronic components that are known to fail such as the height sensors).
