Air suspension problem

Hi, I've thought the rear of my coach was riding a little low for some time now. But, recently on a long trip I heard the back wheels rubbing the wheel wells, and the two rear lights on the HWH system came on. I can still manually raise and lower front and rear as normal, but when I turn the motor off and then back on (travel mode) the rear settles all the way down again. On the side of the road I disconnected the top two solenoid electric plugs, which allows me to manually level and run without the travel mode engaging (thanks to Greg at the Country Coach help line). What do you think has caused this? Will I damage anything worse traveling home like this if I watch it and level it after taking on fuel and water weight?

You have a bad ride height valve. Not sure what year the change over was but at one time, there were two valves in the front and one for the rear. In later years, they changed to a one in front and two in the rear.

Driving with the coach raised manually will not hurt anything as long as you are within limits ride height wise. To low and you rub the tires on the frame and also your driveshaft is out of alignment with the transmission. To high and your driveshaft is out of alignment with the transmission.

To do it correctly, you need the measurements for the air bag height in relation to the frame you can get it close by looking at it.

If one ride height valve is shot, I would go ahead and change all of them as another one will surely follow in failing. Don't ask how I know.

Thanks so much Don, that helps a lot. Since the clues were quite specific, I hoped that someone would be able to put them together to a diagnosis. The trap I try to avoid is a shop learning how to do it on my nickle. I had a mobile repair kid come out on the side of the road because I didn't have jacks or confidence that something wouldn't go PISST and blow my eye out or worse. He had a jack and a good attitude, but didn't have a clue what to do. I'll take a closer look in the manual about the ride height valves, and proper level. You wouldn't happen to know where the desicant cartridge is would you?
Thanks again.

The desiccant cartridge is where the blow off PSSST sound comes from when the compressed air has hit its upper limit. Gotta be in rear, could be either side of engine. On an older rig, it you haven't serviced it for many years, there is likely filmy black oil on its underside blow off hole. It looks like the unit shown in this thread, see PDF's in first post.

"You wouldn't happen to know where the desicant cartridge is would you?"

On a Gillig chassis, I have no idea. If you look in the chassis manual, there should be a picture of the air drier location.
