Removal and Installation

CAUTION: Suspension fasteners are critical parts because they effect performance of vital components and systems and their failure can result in major service expense. A new part with the same part number or an equivalent part must be installed, if installation is necessary. Do not use a part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.

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 electrical connector and the air tube.
1 Disconnect the electrical connector.
2 Compress the quick connect lock ring and pull out on the air tube.

4. 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 retainer.

5. 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 may result in personal injury.

Rotate the air spring solenoid and remove the solenoid.





6. NOTE: Inspect the O-ring for damage and install a new O-ring as necessary. Lubricate the solenoid seal area with silicone grease.

NOTE: When installing the air tubes, make sure the white tube is fully inserted into the fitting for correct installation.

To install, reverse the removal procedure.
