Contents: Removal 🠛 Installation 🠛
Attention
- If it is necessary to replace one air spring, the second spring must also be replaced. Any intervention in the pneumatic system requires replacement of the pipeline seals.
- Before carrying out repairs on the air suspension elements, it is necessary to reduce the air pressure using the valve located on the tee under the vehicle.
Removal
- Place the vehicle on a 4-post lift.
- Reduce the pressure in the pneumatic circuit using the valve on the tee.
- Unscrew the lower mounting nut (2, Fig. 11.11) on the rear suspension beam cup and remove the washer.
- Unscrew the air supply tube fitting.
- Unscrew the two upper bolts (1) securing the spring to the body cup.
- Using a jack, raise the rear beam so that the lower part of the spring can be removed from the beam socket.

Installation
Note: Never stretch the air spring before installing it in place.
- Installation is carried out in the reverse order of removal.
- Check the operation of the pneumatic body height maintenance system and the installation height of the loaded vehicle body, while the dimension H5 (Fig. 11.3) measured between the extreme rear cross member of the floor and the road surface must be maintained:
- 412 mm with 195 mm tires;
- 422 mm with 205 mm tires.
- This size corresponds to the constant ground clearance of the vehicle, regardless of the load (at normal air pressure in the tires).
