How to change rear air suspension on 1999 ford

The arrows point to the location of front and rear compressors.

Cheryl should of changed to standard suspension and gave up the air ride.

it is at the rear end and looks look a guide rail with a plug I would first try to clean the connector and apply carbon conductive grease/NOT LITHIUM==OR DIELECTRIC THERE THE WRONG STUFF/and see if it responds it's only been there for 161/2 years braving winter after winter and its either still good or done from a lack of attention needed taking it out and really cleaning just might save some$$$$$

Your air suspension is leaking, could be a air bag or line or a fitting or a dump valve. Get a spray bottle full of soapy water and start spraying down the air ride components and watch for bubbles.

There are height sensors. One for the rear end and I believe one at each front wheel .If the vehicle is going up on all four corners then chances are you've got a controller issue , but if it's only in the front or rear then you've got a sensor issue.Hope this helps

Cycle the switch by your passenger wheel well (inside the car). Mine did the same thing after not driving for 4 months with the battery drained. In noticed the rear was lower than it should be. Once I turned the switch off then on, it leveled up.

The air suspension can be a tricky thing to mess with. When we were looking to replace just one of the rear bags it was going to be costly. My husband did some checking around online and found Strutmasters.com.
They offered great products at a great price and we were very pleased with the outcome of the replacement of the non air system. If you are replacing the entire system you are looking at a pretty penny. I would check Strutmasters out before you replace the air on your Expedition.

I had a 1999 Expedition. When you put the 4x4 on it raises the vehicle an extra inch or 2.
It may help to turn the 4x4 off. Two wheel drive is a lower air setting.
Your original pump may still be good. The problem can be in the front. The compressor is not filling the front suspension to the cutoff point. It will lift the rear after the front end is at running height. Since you lost the front end first, the remaining air bled out there and then the rear came down. Once you shut down the car the suspension was done, all the air was let go.
There are adjustment solenoids on the body but you need someone qualified to repair this.

just replaced air bag suspension on a 2000 ford expedition, but the check suspension light stil is on how do I disable it.
