It is not necessary to release air from the entire air suspension system; it is enough to release it only from the circuit of the replaced air element.
Do not bleed the air suspension system until the vehicle has been raised.
When disconnecting a Voss type fitting from any air suspension component, do not remove it from the air hose being disconnected.
Do not remove the nipple from the air hose. When removing the nipple from the hose, there is a high probability of scratches appearing on it, which may subsequently lead to air leakage from the system.
Dismantling
1. Raise the rear of the vehicle and install stands.
CAUTION: Do not work under a vehicle supported solely by a jack or lift. Always support the vehicle with safety stands.
2. Remove the wheel.
3. Remove the clamp from the upper support of the air spring.
4. Loosen the screw securing the air spring to the lower arm.
5. Release air from the replaced pneumatic element.

6. Unscrew the bolt securing the shock absorber to the lower arm.

7. Disconnect the shock absorber from the lower arm.
8. Together with a partner, lower the lower suspension arm and release the air spring to access the nipple located on the air hose.
CAUTION: Do not deform the pneumatic element - do not stretch or compress it.
9. Disconnect the air hose.
CAUTION: Before disconnecting or removing system components, make sure that the adjacent surfaces of the joints are free of dirt. Install plugs in the openings of the fittings and pipes to prevent dirt from entering the system.
10. Remove the pneumatic element assembly.
Assembly
1. If a new pneumatic element is being installed, remove the air fitting from it.
CAUTION: Inspect the air element for damage. If the air element is damaged, it must be replaced.
2. Install the air spring assembly, connect the air hose, but do not tighten the connection yet.
CAUTION: Clean the air hose connection area.
3. Together with a partner, install the air spring on the lower arm, turning the air spring so that the mounting flange is in the correct position.
CAUTION: Do not deform the pneumatic element - do not stretch or compress it.
4. Tighten the air hose fitting to 3.5 N·m (2.6 lb ft).
5. Tighten the air spring retaining screw to the lower arm to 7 N·m (5 lb ft).
6. Align the shock absorber with the lower arm, install the mounting bolt and tighten it to 110 N·m (81 lb ft).
7. Pressurize the circuit to secure the upper support of the air element. Install the clamp.
8. Bring the pressure in the air suspension system to the nominal value.

CAUTION: Before removing the support and placing the vehicle on its wheels, it is necessary to bring the pressure in the air suspension system to the nominal value.
9. Reinstall the wheel(s) and tighten the nuts to 140 N·m (103 lb ft).
10. Remove the supports and lower the vehicle.
