Attention
- If it is necessary to replace one air spring, the second air spring must also be replaced. Any intervention in the pneumatic system requires replacement of the pipeline seals.
- Before carrying out repairs on air suspension elements, it is necessary to reduce the air pressure with a valve located on the tee under the car.
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 fastening nut (2, fig. 11.11) on the rear suspension beam cup and remove the washer.
- Unscrew the air supply tube fitting.
- Remove the two top bolts (1) attaching the spring to the body cup.
- Using a jack, lift 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 functioning of the pneumatic system for maintaining body height and the installation height of the loaded vehicle body; in this case, dimension H5 must be maintained (pic. 11.3) measured between the rearmost floor cross member and the road surface:
- 412 mm with 195 mm tires;
- 422 mm with 205 mm tires.
- This size corresponds to a constant vehicle ground clearance, regardless of load (at normal tire pressure).
