Help! Rear air suspension won't charge

[Dyno Bill]

I had my rig on fully extended leveling jacks for a couple of days while working on the generator. After pulling the levelers up the rear air bags will not charge to raise the rear of the coach, looks like one bag my not be seated. The air pressure goes to about 75 then seems to dump down to about 50 before it starts climbing again. What's wrong with my rig?

Hi Dyno Bill,
I've been there and done that. Try this,
1. Raise the coach with the jacks. Not all the way, about 1/2 to 3/4 of the way.
2. Start the engine. Wait about 10 seconds.
3. Store the jacks, with the engine running.
Let us know if this works.

Thanks Gary, that worked. Also I had to go under the coach and push the air bag to one side as the top and bottom mounts are not centered, I'm thinking this is why it did not go back on it's own. Possibly the whole axle is off to one side, what does it take to recenter?

Hi Dyno Bill,
The weight of the coach and the bag's normal travel should keep it where it is suppose to be. To have the axle checked to make sure it is where it is suppose to be, a certified chassis shop visit would be necessary.
