I was wanting to know how the air system levels out the rear end. The driver side always sits about an inch lower than the passenger and i only see 1 level sensor at the middle of the axle. so is there another air valve that assures the solenoids are provided with a equal volume of air or could my drivers solenoid be weak? I have new airbags with new solenoid o rings and no leaks at the bags or solenoids

thanks

 

When pumping up the solenoid valves for both rear airbags open and the pressure is equalized. Since they're not pumping up equally I would suspect a problem with one of the airbags itself or the solenoid valve mounted on it.

 

Both bags are brand new. I guess I will just replace both solenoids so they will perform equally

 

Did the new bags come with solenoids or did you reuse the old ones?

 

I reused the old ones

 

Yep, could be one of those or the O-rings on them that are not sealing properly.

 

Also, if you'd rather try and replace just the O-rings first before spending anywhere from $25-$75 on a new solenoid valve then read here: https://www.ford-trucks.com/forums/1...orner-low.html
