Removal and Installation
WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components
supporting an air spring without either exhausting the air or providing support for the air spring. Failure to follow these instructions may
result in personal injury.
1. If the air spring solenoid valve is functional, use the scan tool to vent the appropriate air spring(s).
2. With the vehicle in NEUTRAL, position it on a hoist.
3. Disconnect the air spring solenoid valve electrical connector.
4. Disconnect the air line at the air valve.

Compress the orange quick connect lock ring, then pull downward on the air supply line.
5. CAUTION: Remove any dirt or other foreign material from the air spring assembly prior to removing the air spring solenoid valve from
the air spring assembly.
Remove the air spring solenoid clip.
6. WARNING: The air spring solenoid valve has a 2-stage release. When removing a non-functional solenoid and the air spring is inflated,
carefully rotate the solenoid counterclockwise until it reaches the first stage to release the air from the air spring. Turn the solenoid to the
second stage to remove the solenoid. Failure to follow these instructions when removing a non-functional air spring solenoid may result in
personal injury or damage to components as high pressure air is vented uncontrolled.
Rotate the air spring solenoid and remove the solenoid.
7. NOTE: Inspect the air spring O-ring for damage and install a new O-ring as necessary. Lightly lubricate the solenoid seal area with silicone
grease.
NOTE: After installing the solenoid, it is necessary to inflate the air suspension system.
NOTE: When installing the air spring solenoid, make sure that the electrical connector is positioned away from the air spring.
NOTE: When installing the air lines, make sure the air line is fully inserted into the fitting for correct installation.
To install, reverse the removal procedure.
