How I fixed my Expedition Rear Air Suspension from Sagging

[@andyyoung8545]

I just wanted to share my experience for anyone who might be struggling with Expedition air suspension issues. I had both the air springs and the compressor replaced about 3 years ago. Over time though it began to fail. At first only when it was very cold (well below freezing). Later it failed in other situations. I had it inspected but multiple mechanics. They all said everything was fine and that the air springs held air. After lots of frustration I finally replaced the compressor myself and haven’t had a problem since. So if you have replaced the air springs and are still experiencing drops in the rear it’s probably worth testing the pressure output from the compressor… or just replace it without testing which is what I did. It cost just over $300 from an auto parts store and took about 45 minutes. Good luck!

Thanks for leaving your experience here! That's what this channel is all about!

DID that leak on the passenger side cause BOTH sides to sag overnight? and if so, did it fix both sides?

Great teaching video… Thanks

How do you turn on the air ride switch? Mine I sagging from both sides. Watching your video makes me think I just have a fuse out

[@1tbtools]

Some models have them in the rear driver panel, pop your hatch, pull out cutout plastic panel there is an on and off switch there. Mine you have to maneuver through the center dashboard settings.

@@mrgmrg9943 hope it works out. UPDATE: I had to replace my whole airbag unit! Arnott from Amazon was the way to go!

[@mrgmrg9943]

@@1tbtools was this because of the part you installed or just the airbag went out in general? And how did you know it was the airbag and not the solenoid again

@@mrgmrg9943 I sought council from a master tech, he said likely because they were the OE bags they were likely dry rot, enough to cause the slow leak over night.
