I sprayed down the bag today with Soapy water and could not find any leaks. However Keep in mind that I could not inspect the whole bag as I did not put it on a lift. But GM Parts Direct does have them. What I cannot believe is that the Dealer does not stock them. That is crazy.

Part numbers are as follows. All can be found on GM Parts Direct Web site

Air Spring Part #15838306
Height Sensor Part #15124929
Level Controller Switch Part #15058259
Pump Relay 15319851
