Looking for someone who might be able to help with a rear air suspension issue:
1- Purchased 1998 Expedition new - has 120K actual miles
2- Exceptionally maintained and garage kept
3- Never wrecked or in an accident
About two weeks back, the rear end was drooping because both air bags had "leaked" down.
Started truck and rear of truck immediately came back up to its proper position (so pump is functioning)
Let truck sit for two days and all was still well!!!
Then drove truck to town and back - the morning after, all appeared well. However that afternoon the rear end was drooping once again. Started the truck and the rear end of truck came back up to its proper position.
Then everything went well for almost a week and then the rear air suspension lost air once again. Starting the truck resolved the problem once again.
Obviously, something is failing. Has anyone else experienced this same issue?
I may have to wait until things get worse, but what is the most likely culprit?
Thanks so very much!
