Thanks for the information:
Here is a detail of the event:
Started the coach and walked outside to disconnect power and check the surroundings before backing out.
Heard the air leaking on the driver side rear axle area.
Heard the sneeze and and went inside to back her out into the drive way.
Killed the engine and walked outside to the rear axle heard the air leak but could not find it before it stopped.
Went back in side started the engine again and back outside to the axle.
I could hear the leak but the engine noise made it too difficult to locate.
Killed the engine and ran to the axle area and found the hose leaking air. It stopped 30 seconds after I found it.
Had a friend go in the coach and crank it again waited to hear the air leak and got him to kill the motor. As I wiggled the arm in the picture the air would stop and start leaking.
Took pictures and went to do the other work I had planned.
Parked the coach and extended the jacks for storage, just in case it leaks down....then found my step issue (another thread)
Will not be able to work on it again till this Saturday but I am hopeful it was operating as designed.
I do know the bags were fully inflated for the trip out of storage and back in. I manually dumped the rear air a few times trying to see if that was working properly during testing and the refilled and sneezed each time.
Thanks again for all the comments
