Air Spring Refold

Vehicle Dynamic Suspension

Air Spring Refold

WARNING: 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.

NOTICE: 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 replaced.
- 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 the 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.


NOTICE: Prior to installing an air spring, make sure the air spring is in the correct shape with no folds or creases. If the air spring is not in the correct shape, carry out air spring refold before installing the air spring, to prevent air spring damage.

1. NOTICE: Do not clamp any portion of air spring piston or damage to the air spring may occur.

Place the air spring on a flat surface.





2. Remove the air spring solenoid to expand the collapsed air bag.





3. Push the membrane down over the piston to the correct height.





4. Install the air spring solenoid to help maintain the correct height.
