Symptoms: Intermittently ride control light comes on, back suspension lowers so that wheel well edge is below top of tire, ride becomes rough. Hissing noise comes from rear driver side around tire – verified no leak in tire. If I turn off the ride control system using the switch in the trunk and then turn it back on, the rear suspension rises back up, the hissing air leak noise goes away and for a while the rear suspension seems to hold pressure fine. I’ve tested it in my garage by turning the key to on to turn on electric but not engine and sitting on the rear bumper to cause the rear suspension to inflate under load, the rear suspension inflates and holds pressure without any hissing air leak noise, though the driver side was substantially higher.

At first I thought this was a leak in the rear driver side air strut or both rear air struts. I was ready to go buy one and attempt the install myself but now Im wondering since the leaking sound is intermittent and the same side at times over inflates if the problem isn’t with the sensor causing the suspension to deflate when it shouldn’t.

You obviously have a leak somewhere. At this point the easiest way to resolve your problems is to install a "spring changeover" kit and get rid or the air ride all together. You'll have trouble finding parts to repair it anyway.

You need to swing into your friendly Ford dealer and have them plug in the old Star tester and see what code(s) is being stored in the ELC controller. A lot of times a faulty ride level sensor will cause that kind of symptom, but you need to find out which one.

If you do the conversion, you'll have to convert all four corners.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
