04 Alfa Suspension Question

[APlusParts]

I have an 04 alfa see ya it has a freightliner chassis with air suspension my right front suspension keeps going up all the way when driving. Im not sure if im wording this correctly or not but the air bags for the suspension pressurize which acts like a spring. with that my right front stays all the way up (full pressure). I have worked in the junk yard business my whole life as most lincolns they have air suspension very similar to my mh, as in a lincoln with this problem just change the height sensor for that wheel. well there is not one height sensor anywhere on the motor home so my question is what controls these air suspension bags and has anyone had any issues like this that can advise me on what to do? thanks in advance

There should be three ride height control valves on your chassis. Two on one end and one on the other. I don't know whether the single valve is on the front or rear for your coach, but if you're only having troubles with the right front I would guess that you have two in front and one in the rear.

I would recommend having a Freightliner shop check it out.

And it may be the ride height valve diagonally opposite(left rear) that is out of adjustment. It's an adjustment that you can learn to make yourself.

I dont think it would be adjustment and i dont think i said this earlier but sometimes the height is fine and others the wheel it all the way down, does that sound like an adjustment issue? or parts issue?

Yes. First thing to try would be the adjustment . If that's no help then replacing the ride height valve in question is in order.

Have your serial number handy. Ask for an air system diagram. That will tell you if you have to old configuration of two front ride height control valves and one rear , or the newer , one front, two rear.
Talk in another thread is that in order to correct a RF low problem , owners are having to move the ride height valve from the LR to the RF in order to correct this problem. I'll post the thread info.

EDIT: Read the thread.
Freightliner front right corner sometimes lower .
