Inflate the tires to the correct PSI as listed on the driver's door post and in the owner's manual. Tires are part of the suspension and over inflated tires will cause a harsh ride. Replace the shocks/struts if you have over 75,000 miles on the vehicle. Worn tires also cause a harsh ride so replace the tires if they are worn out. Other than that there is not much you can do.

Fit softer shock absorbers if you want a softer ride, or if it rolls around too much, have a tortion bar fitted.
Changing springs to a performance type will also affect things, but talk to the manufacturers before selection.
Fitting different tyres will also affect handling and ride.

Details just in english; front wheel drive and some high-end rear wheel drive cars generally employ an Independent Rear Suspension, or IRS. In this case each wheel connects to the car by a group of lightweight control arms. This design saves weight, improves vehicle handling and does wonders for ride comfort.


Inspecting wheel alignment begins with a check for loose or faulty suspension components and requires the use of a costly machine to measure all the critical angles. The inspection and measurement phase takes perhaps a half-hour for each end of the car. Needed corrections can be fairly simple, or they can add to labor considerably should installation of retrofit parts be needed.



HERE some tutorial about this subject.


Hope helps.

I have an 2004 Ford Expedition Eddie Baurer, Check Air Suspension light is on. The suspension is not working at all truck rides very low and bounces every time a bump is hit, what could be wrong?


Any part of the air ride suspension system could have failed.
I would replace the air suspension, with a conversion, such as strutmaster or similar product,other wise you have to diagnose your current system and repair.

99 expedition two wheel drive passenger side goes up higher than the drivers side.uneven ride! whats a ride height sensor?


height sensor is a sensor that control air compressor on air shock.it keep vechicle level.if height sensor senses distance between frame and suspension .it will admit air to shock by controling the air compressor.check the air shock on driver side.BESURE TO TURN OFF ELECTRICAL POWER TO AIR SUSPENSION BEFORE RAISING VECHICLE.

No power to rear bags its down but wont air up bags dont seem cracked unplugged connector no power I tried resetting still no power


is switch on?
The air suspension switch and bracket is mounted below the RH side of the instrument panel.

Dealer can run diagnostic test with scan tool for fault codes.
----------

The air suspension system is designed to improve ride, handling and general vehicle performance for static, on-road and off-road driving conditions:
  • Ride is improved by using an air type spring (the soft ride is inherent).
  • Handling is improved by maintaining constant vehicle attitude.
The system consists of unique rear air springs, the air compressor, air lines, air spring solenoids, height sensor, air suspension control module, attachments and associated signals derived from both driver and road inputs. With these components and signals, the air suspension control module commands changes in vehicle height that are necessary for the load leveling features.
The load leveling feature rear air suspension (RAS) systems shall automatically make adjustments in vehicle height so that the vehicle is always at trim height and constant front-to-rear vehicle attitudes are maintained over the expected load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle's left and right sides for the RAS system shall be restricted to what can be reliably achieved with one air suspension height sensor.
The system uses one air suspension height sensor, a steering sensor, generic electronic module (GEM) and other vehicle sensors to measure driver and road inputs. The system changes vehicle height using an air compressor, two air lines and the use of air springs with air spring solenoids.
The air suspension system holds vehicle height when the rear hatch or any door is opened. The system stores rear vehicle height the moment any open door is detected. The system then maintains this height regardless of the addition or removal of a load. The system will return to its commanded height when all doors are closed or the vehicle speed exceeds 16 km/h (10 mph).
------------------------------------
Air Spring
RAS vehicles use air springs in the rear. The air springs provide a varying spring rate proportional to the systems air pressure and volume. The air suspension system regulates the air pressure in each air spring by compressing and venting the system air. Increasing air pressure (compressing) raises the rear of the vehicle while decreasing air pressure (venting) lowers the rear of the vehicle. Vehicle height is maintained by the addition and removal of air in each air spring through an air spring solenoid installed in the upper spring cap and energized through the air suspension control module.
The two air springs support the conventional rear leaf coil springs.
Air Suspension Height Sensor
One air suspension height sensor is mounted on the vehicle. The air suspension height sensor sends a voltage signal to the air suspension control module. The output ranges from approximately 4.75 volts at minimum height (when the vehicle is low or in full jounce), to 0.25 volts at maximum height (when the vehicle is high or in full rebound). The air suspension height sensor has a useable range of 80 mm (3.2 in) compared to total suspension travel of 200-250 mm (8 to 10 in) at the wheel. Therefore, the air suspension height sensor is mounted to the suspension at a point where full rear suspension travel at the wheel is relative to 80 mm (3.2 in) of travel at the air suspension height sensor. The air suspension height sensor is attached between the No. 5 frame crossmember (upper socket) and the panhard rod (lower socket).
When the air suspension height sensor indicates that the rear of the vehicle is lower than trim under normal driving conditions, the air compressor will turn on and pump compressed air to the air springs. When the sensor indicates that the rear of the vehicle is raised above trim under normal driving conditions, this will cause the air to be vented from the air springs to lower the vehicle back to its trim height level.
Compressor Relay
The compressor relay is energized by the air suspension control module to allow high current to flow from the battery to the compressor motor.
  • A solid state relay is used in the air suspension system for air compressor control. The relay incorporates a custom power metal oxide semi-conductor field effect transistor (MOSFET) and ceramic hybrid circuitry. The relay switches high current loads in response to low power signals and is controlled by the logic of the air suspension control module.
Air Suspension Control Module
NOTE: The 4WAS air suspension control module is used for the RAS system. The internal processor recognizes external circuitry to determine if it is installed in a 4WAS or a RAS equipped vehicle.
NOTE: The air suspension control module is calibrated with information from the air suspension height sensor. A new or exchanged air suspension control module requires a ride height adjustment calibration process to be performed.
The air suspension control module controls the air compressor motor (through a solid state relay), and the air spring solenoids. The air suspension control module also provides power to the air suspension height sensor. The air suspension control module controls vehicle height adjustments by monitoring the air suspension height sensor, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals, and the brake pedal position (BPP) switch. The air suspension control module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing the vehicle and related components.
The air suspension control module monitors and controls the air suspension system through a 32-pin two-way connector. The air suspension control module is keyed so that the air suspension control module cannot be plugged into an incorrect harness. There are two sides of the harness connection to the air suspension control module. Each is uniquely colored and keyed to prevent reversing the connections.

Rear Suspension 2002 Ford Expedition


they make aftermarket spring kits for air ride removal. you can also get used parts from an expedition without air ride. My personal opinion there isn't a great difference in ride quality the only advantage the air ride has is that it will raise the vehicle ground height when in 4x4
