If I correctly understand what you are describing, it sounds like the air valve is the one for distributing air to the right front air suspension bag. There is a vertical rod with one end attached to the axle (or sway bar - not sure which) and the other end attached to a horizontal bar which attaches to an air valve (Height Control Valve)for adjusting the amount of air in the air bag.
I suggest you confirm whether the air valve is bad and, if so, replace it. I believe the front air suspension for your model year might have been the Neway AS120. Neway is apparently part of the Holland Group now. See this link for literature for the Neway AS120 (page 8 has the diagram for the Height Control Valves):
