Anyone reasonably mechanically inclined can replace an air valve. There's nothing complicated about one. Air bags are a little more of a challenge on some buses (as it often needs to be jacked up a bit), but still within the realm of a DIY fix.


A brake job borders on mechanic territory, depending how mechanically inclined one is, and it takes some heavy duty tools to remove the tires, lift & support the axles (Do *NOT* rely on a jack alone! Use stands!) and at some point there's a difference between owning $2000 in tools and just paying a shop to do it.

There still might be an air leak because I didn't get that far in checking things out.



Your problem is the same problem we have had continually with the Thomas Saf-T-Liner EF that the church owns. We have had to replace the rubber connectors in the height control linkage too many times.



Our repair tech suggested the problem arises with the church bus because it isn't used every week. It sits around long enough most weeks that the air leaks out of the air bags letting the suspension go all the way down. With the air bags going flat so many time the rubber hose/tubing on the height adjustment would get bent over and back again so many times the rubber would fail.



We replaced the hose/tubing with a Kenworth part that is metal with a rubber eye. Now if the bags leak down the ends won't be bending back and forth.

Get that hose and reclamp it. it is used so when the suspension is flexing or drains out of air, it does not bend any parts or break any valves. you can charge the air up and move the valve by hand to see if the suspension fills up again, I bet it will.

Well I finally got my rear suspension fixed. I did not order the valve kit for the bags but decided to replace the rubber hose and its working. One day I will have to revisit this job because the molded rubber piece on the actuator rod is cracking. The next job is ac repair!!

It doesn't look like we'll be seeing too much of an impact from Barry here in E TX.
LA looks to get a good rinsing, tho.
