Air Suspension Structure

1. Stud

A permanent part of the bead plate assembly used to attach the airspring to the suspension.

2. Combo Stud

Combination mounting stud and air fitting.

3. Blind Nut

A permanent part of the bead plate assembly providing an alternate mounting system to the stud.

4. Air Fitting Hole

A tapped hole usually 1/4" N.P.T. providing air entrance for the part.

5. Bead Plate

Permanently crimped onto the bellows at the factory allowing complete part leak testing prior to shipment.

6. Bellows

The heart of an Airide spring. Includes at least four plies, or layers, of material–an inner layer, two plies of cord-reinforced fabric, and an outer layer.

7. Bumper (Optional)

A solid molded rubber fail-safe device used on many suspension applications. Prevents excessive damage to vehicle and suspension in the case of sudden air pressure loss.

8. Piston

The lower section of the 1T and 1X style of airspring made from aluminum, steel or fiber reinforced plastic. Provides lower mounting arrangement for the airspring in the form of tapped holes or studs.

9. Piston Bolt

Attaches the piston to the bellows assembly. Extended, in some cases, to serve as a means of attaching the spring to the suspension.

10. Girdle Hoop

A ring between the convolutions of the convolutedtype air spring.

*Removal Warning & Notice

Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury.

Any air spring which is unfolded must be refolded prior to being installed in a vehicle. Refer to the procedure. An incorrectly folded air spring could rupture, altering the handling characteristics of the vehicle. If a vehicle has been driven with an incorrectly folded air spring, a new air spring must be installed. Failure to follow these instructions may result in serious injury to vehicle occupant(s).

Failure to observe the following instructions may result in a sudden failure of the air spring or suspension system.

Any rear spring which is unfolded must be refolded prior to being installed in a vehicle.

The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position.

Incorrectly folded air springs found on vehicles during pre-delivery inspection or after use must be installed new.

Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop.

When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using the air spring fill procedure.

After inflating an air spring in the hanging position, it must be inspected for correct shape.

Note

The vehicle must be positioned on a suitable lifting device prior to deflating the air suspension system.

With the vehicle in NEUTRAL, position on a hoist until the wheel and tire assemblies are slightly above the ground.

2.Using the scan tool, vent the air springs.

3.Remove the air spring retainer.

4.Detach the air spring from the rear axle.

5.Remove the air spring in the following sequence.

1.Disconnect the air spring solenoid electrical connector.

2.Compress the quick connect locking ring and pull out the air tube.

3.Remove the air spring.
