One thing I have seen with some of the arrangements is that the air spring is mounted with the piston rod pointing up. The air springs are made to operate with the piston rod in a downward orientation. The reason for that is there is a small amount of oil inside each spring that provides lubrication for the seals (as per manufacturers). If mounted with the rod up it will eventually run dry and loose pressure.
