Hi everyone, I am hoping to get some input on a problem I am having with my air leveling kit installed in my 2003 4Runner Ltd.

Now, I've seen similar issues to this but I feel that a new thread is warranted because it is a different issue completely.

I have noticed in the recent past that the truck is losing air out of it's bags after sitting for an extended period of time, on 60+ mile trips, and I've also noticed the air compressor running if I am waiting for my wife in the mall for 20 or so minutes.

As a result, the truck is running at it's lowest point and each bump/pothole I hit seems like the sky is falling and I feel like I'm riding on a mechanical bull.

What is happening, is the Height control *reservoir assay* is leaking the air held in the reservoir (see picture below). The red line is where I can tell air is leaking from. I've looked at the diagrams of how this system works and from what I can tell; there is no "gasket/o-ring" that can be replaced to fix this leaking issue.



Does anyone know of someone who's had this problem or if it is repairable? The reason I ask is because the assay itself is ~$600 depending on what wholesaler you go through, and I'd rather replace a gasket or seal than spend the $600 now to fix it.

I am looking into replacing the air leveler completely at some point, but the funds are not there for right now.

Thanks for your help ahead of time.
