2010 Expedition 4DR Limited Rear Air Suspension Leak Down

[Old Man Arizona]

My Expedition rear air suspension on the driver's side leaks down over night, but when I start it up, it fills with no problem and there is no problem while I am on the highway. If I leave it over night, I come out to the vehicle and it's sagging. I am looking for a proper diagnosis and the correct OEM parts so I can take care of this issue. I went to the manufacturer and these parts are discontinued according to online sources. Does anyone know where I can get the proper quality parts so I am not replacing EVERYTHING in the rear suspension system? As y'all know, it gets pretty pricy guessing at what it may be! Please give me suggestions and/or direction on what I should/can do. Thank you in advance.

Regards,
Old Man Arizona

Hello OMA. Did you get your suspension problem figured out?

I had a bad sensor & leaking pump on my 011 EL replaced at a local stealership last year, $800 parts & labor w/ lifetime warranty, so no mo worries about that
