Air springs height adjustment
Adjust the air springs clearance with the
height control valve
5. It is necessary to adjust clearance on "fill
cycle".
a) Disconnect the link. It is equipped with
a rubber bushing that allows easy
disconnection.
b) Lower the control arm to release some
air from air springs.
c) Raise the control arm to fill the air
springs (the valve is now in "fill cycle")
and connect the link back in place.
6. Using a hammer, tap gently on the arm
secured to the sway bar. Even if the fasteners
are properly tightened, it will rotate around the
sway bar. Rotate the arm secured to the sway
bar to increase or decrease the clearance as
shown.
7. Allow 15 minutes to the air system to settle
then measure the new clearance. Repeat
previous step if necessary.
