    Tire pressures are all the same at 37 psi.

  • tacampbell42 Dec 30, 2010

    The problem is the air bags on the suspension are inflated too high and create a stiff ride on the left side, this just started yesterday. This has the Expedition sitting higher on the left side with no give to the suspension, which causes it to bounce over bumps.

    Do you mean the info read out on the dash?

  • tacampbell42 Dec 30, 2010

    Where are those sensors located?

  • tacampbell42 Dec 30, 2010

    I just checked the message center on the dash and it says "air suspension ok" but it really isn't.

  • tacampbell42 Dec 30, 2010

    Where is the suspension height sensor?

  • tacampbell42 Dec 30, 2010

    Is there a linkage at every wheel or just on the front?

  • tacampbell42 Dec 30, 2010

    The left front one was disconnected. I reconnected it. I'll check the back.

  • tacampbell42 Dec 30, 2010

    I can't find one on the rear left wheel. Where is it located? Do you have a diagram for that one?

  • tacampbell42 Dec 30, 2010

    Thanks for all your help things seem back to normal after re-attaching that front one. I took it for a drive and the other side came off and I knew how to dix it. Thanks again. Tim

    Air Suspension Height Sensors


    There are two sensors used for the front suspension and one
    sensor used for the rear suspension. The sensors send a voltage signal to the
    4WAS module. The output ranges from approximately 4.50 volts at minimum height
    (when the vehicle is low or in full


    jounce) to 0.50 volt at maximum height (when the vehicle is
    high or in full rebound). The sensors have a usable range of +'- 450 compared
    to total suspension travel of 196 mm (7.84 in) at the front wheels and 240 mm
    (9.6 in) at the rear wheels. Therefore, the


    sensors are mounted to the suspension at a point where full
    suspension travel at the wheel is relative to the travel at the height sensor.
    The front height sensors are mounted to the frame and the links are attached to
    the upper arm ball studs. The left and right sensors


    have opposite polarity and are not interchangeable. The rear
    height sensor is mounted to the frame and the link is attached to the rear
    lower arm bail.

How difficult is it to remove airbags in a 2001 ford expedition and replace with shocks?


With out seeing the vehicle, it is difficult to say. There are fuses that control the small compressor that inflates the bags, the wiring could be faulty. the compressor could be bad. The control switch could be bad, I am not sure what activates the compressor on that model, weather it is automatic load leveling or manual leveling with a switch inside the car.
It might pay to get a manual such as haines for your perticular model. Sorry I couldnt be more helpful, but electricly controled systems like this are hard to trouble shoot without seeing them.

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.

2006 F-150 Exceptionally stiff ride. Bought truck used. Can feel ever crack in pavement. It's like riding a hardtail. Front end shudders with every bump. Truck is approx 2" taller than other identical...


A few things contribute to the stiff ride: 1. Tires and tire pressure... if you're running 50psi or above...that will contribute.If you aren't carrying loads, keep the tire pressure at the bottom of the recommended range. 2. aftermarket additions to the suspension- if you can contact the previous owner, you may want to ask. ei: helper springs, lift kits, special shocks 3. Empty truck bed will emphasize the bumps. Put a little ballast in the bed of your truck. I've kept sand bags or tool boxes in mine to soften the blows...
