Air suspension not airing up level.

[Cuylerpilot]

Well in getting ready for a trip I started the coach up and built up air pressure and the coach seemed to be leaning to the left. The air bags I could get to all seemed to have air in them. This happened at the end of the day and I needed to take a shower and get ready for work if they cal call(it sucks not having a regular schedule). Later I went out to the rv and decided to air down the bags with the air dump and see what it did the next time. I completely aired down the bags and started the coach and went out to see what it was doing. I'm getting air to both sides but the right side seems to be about a half inch to a inch higher on the right side. but in looking at it, it did not seem to be leaning as much as it did the first time. I don't hear any air leaking from either side, the only air I hear is from this device which I have no idea what it is
The black tube that comes out of the box is soft, and when I pinch it shut I can hear something inside click inside, like a valve closing, but when releasing it it continues to leak a small amount of air. I'm guessing and hoping this has something to do with it as it is really easy to get to. in either case, what the heck is it.
Sorry for the long post, any ideas.

You have three air ride height valves that control the air to the air bags, two valves for the rear axle, one valve for the front axle.

One of your rear ride height valves has failed, is sticking, or the linkage to it is sticking, or the linkage has slipped out of adjustment.

You have a ride height valve just inside each rear wheel, that makes two ride height valves at the back. You have one ride height valve just above the middle of the front axle.

I'm pretty sure the black ball under the box is the vacuum resevoir for the dash A/C and heat controls. It looks like the hoses from the black box are going to this ball so I would assume it is the vacuum pump and would have nothing to do with the leaning problem. Just my $.02 Good Luck

Thanks Jim & Tom, I'll crawl under the rear end when I get back, hopefully this will be a easy fix.

Don't do it until the frame of the coach is properly supported by jack stands that can take the full weight of the coach!

When you are working on those valves, any slight movement of the control arm can have a big effect on the height of the coach, including suddenly lowering the coach -- you don't want to be under it when that happens!

Please be very careful and take this seriously.

Agreed!

Anytime I have needed ride height air valve replacement or adjustments, I have chosen to pay the money to have someone else do it for me.

It pays to know how the system works so you know exactly what you want done.

Just sayin'

My rig was doing the same thing. A few leaks, one valve leaked, and some magnetic actuator needed replacement. No clue how that works. Now she rides level and smooth 😜👍
