Remove
WARNING: The air suspension system can be pressurized
up to
10 bar (150 lbf/in²). It’s always important to make sure that dirt or
grease
doesn’t enter system. Always wear hand, ear and eye protection when
servicing
the air suspension system.
WARNING: Do not inflate the air spring assembly unless it
is supported on both ends by the vehicle frame and suspension system.
Failure to observe this warning may result in serious injury and
damage to the air springs assembly. YOU SHOULD NEVER
ATTEMPT TO DISMANTLE THE AIR SPRINGS.
1. Raise the vehicle on a hoist or other adequate structure. WARNING:
Always support the vehicle on safety stands. Refer to your
owner’s manual for correct lifting instructions. Remove road
wheel.
2. Disconnect the pipe from top of air spring. Removing the air fitting
will depressurize the air spring.
3. Seal off hose to prevent dirt or grease from entering system.
4. Remove the 2 clips securing the top of the air spring to chassis.
5. Collapse the air spring.
6. Rotate the air spring to unlock it from axle, and remove the old air
spring from the vehicle.
7. Remove the old air connector from the pipe.
CAUTION: When refitting the new air spring, do not allow the
vehicle to rest on the deflated air spring. The chassis must be
supported until the new air spring is inflated.

1. Locate the two holes for the spring seat retaining bolts. Run a
10mm x 1.50 tap thru these holes to ease installation of retaining
bolts.
2. Install lower spring seats onto axle.
3. Jack up axle to release tension from shock absorber. Remove lower
shock bolt. Release ABS sensor lead from bracket.
4. Install upper spring isolator to top of spring. Note: top has the
tighter coils at top.
5. Lower axle until the spring can be installed in place.
6. Raise axle making sure spring stays aligned in place. Reinstall the
shock bolt and clip ABS sensor lead in place.
7. Repeat for opposite side.
8. Reprogram slabs computer to coil springs using Autologic or Test
Book diagnostic system (this will disable the air suspension
system.)
