Air ride slow leak! Please help!
So I'm new here, sorry if I'm not doing this right.
I have a 1998 Expedition XLT 5.4 2wd. Long story short I have a slow leak on the rear air bag suspension system that I can not find. It takes about two days of non use for it to be sitting near the ground. Here's the details.
I used soapy water on everything, numerous times and found nothing.
I replaced the air compressor a few years ago.
I cut power to the system for two days and it didn't drain!
Tested the relay, seems to work fine.
Control module and height sensor look fine.
So I replaced the solenoids, thinking that was the problem and it still drains...
I do not want to replace the rear bags with springs because I tow a large travel trailer often, and love how it self levels.
