Rear Air Springs problem

I have a 98 Expedtion and it's tilting lower on the back left, I'm assuming it could be due to a leak in my air spring, Can someone help me in giving me info how to replace them and if I'm making the right assumtion that it is the air spring. THANKS

Just Bought some Air Spring from the website and, I thought it was hard to install the new air suspension.. Man it took little time to replace them with new ones.. Now my EXpedition Up and not slumped at the rear anymore.. It fixed my problem,

Turn switch OFF under passenger side dashboard
Ton Jack
Remove the Pin on the bags
Turn counterclockwise on the solinoid to release compressed air
replace Solinoid O-rings and reinstall.
I replaced the Compressor Dryer while I was at the job

Sweet...go to know. How long did it take you? Did you replace just the one or both rear?

I REPLACE BOTH. and Dryer from the compressor
It took the most probably less then 30min -1hr.. Here are the steps carefully

Removal Air Springs

1. Turn OFF SUV and open the doors to let air vent.
2. Turn Off the Compressor Switch
3. Jack Up the SUV and and puut jacks and tire brick for saftey
4. Take Tires OFF both sides
5. Support Rear Diff and remove the pins on top of the Air Spring
6. Then Remove the Clip that holds the Solinoid onto the A-SPrings
7. REMEMBER HOW WHICH POSITIONS BOTH BAGS SITS ON THE AXLE
8. Counter Clockwize turn the solinoid and air depresses, then the A-springs
becomes a flatten sandwich. and remove A-Springs

Installation Air Springs

1. Replace A-Springs and O-Rings
2. Make SURE Bottom of the A-Springs Clips are seated properly
3. INSTALL A-Springs from removal process
4. Turn ON Compressor and here it adjust when started, it will make a big POP noise because it's inflated and the clip is going into the seat of the AXLE

Correct me if I'm wrong, but when I had my '97 Expy you had to leave all of the doors CLOSED in order for the suspension to vent/lower the vehicle.

Not really sure but I followed these instructions to find a leak

THE "EASY WAY" TO FIND A LEAK

By far, the easiest way to test for a leak, is to allow the car to vent down after shutting off the engine and opening and closing the door.
