DISASSEMBLY

1. Place the vehicle on level floor.

2. Chock the wheels.

3. Raise the frame.

4. Support the vehicle with frame stands.

WHEN SERVICING THE VEHICLE OR ATTACHING AN AIR SPRING AND THE VEHICLE IS ON THE

GROUND, PRIOR TO AIRING THE SUSPENSION SYSTEM MAKE CERTAIN THE AIR SPRING

LOCATOR IS INDEXED INTO THE UPPER AIR SPRING BRACKET PROPERLY, AND THE AIR

SPRING IS FULLY SEATED ON THE SPRING TOP PAD. FAILURE TO FOLLOW THESE

INSTRUCTIONS CAN RESULT IN PREMATURE AIR SPRING FAILURE, CAUSE PERSONAL INJURY,

OR PROPERTY DAMAGE.

PRIOR TO AND DURING DEFLATION AND INFLATION OF THE FRONT AIR SUSPENSION SYSTEM,

ENSURE THAT ALL PERSONNEL AND EQUIPMENT ARE CLEAR FROM UNDER THE VEHICLE AND

AROUND THE SERVICE AREA, FAILURE TO DO SO CAN CAUSE SERIOUS PERSONAL INJURY,

DEATH, OR PROPERTY DAMAGE.

5. See additional Air Spring Cautions and Warnings in the Important Safety Notice Section

of this publication prior to inflating or deflating the suspension system.

6. Remove the air from the air system by disconnecting the height control valve linkage(s)

at the rubber grommet(s) and allowing the lever(s) to drop. This will exhaust air from

the system.

7. If the air spring is damaged and the suspension is deflated, it will be necessary to raise

the frame and support the vehicle with frame stands to obtain adequate clearance for

air spring removal.

8. Disconnect the ¼" NPT air fitting from the air spring.

9. Remove the lower ½" air spring locknut from the piston stud to remove the air spring

from the top pad, see Figure 9-9.
