Removal
- Removal of the rear suspension beam with the body height maintenance system is carried out in the same way as the rear suspension beams without the body height maintenance system, taking into account the following.
- Unscrew the nut (2, Fig. 11.11) the lower mount of each air spring.
- Loosen the nut securing the ball joint pin to the beam (3, Fig. 11.16) and disconnect the body position sensor rod.
Note: When replacing the rear suspension beam, the air spring bases must be centered on the cups of the new beam. This is necessary to ensure normal operation and durability of the air spring.
Centering of air springs
- Attach the Sus. 1193 device to the air spring without loosening the upper mounting bolts.
- Drill out the lock washer coaxially (2. Fig. 11.10) through two holes (1), then fix it with two rivets with a diameter of 3.2 mm.
- Remove the Sus. 1193 tool, then install the lower washer (3) and screw on the nut (4).

Installation
- Installation is carried out in the reverse order of removal, taking into account the following.
- Tighten the nuts and bolts securing the silent blocks to the required torque at the normal height of the loaded vehicle body.
- Bleed the brake system.
Note:
- Check the operation of the pneumatic system for maintaining the height of the body and the installation height of the body of the loaded vehicle, while the dimension H5 (fig. 11.3) measured between the rearmost floor cross member and the road surface: 412 mm with 195 mm tyres, 422 mm with 205 mm tyres.
- This size corresponds to the constant ground clearance of the vehicle, regardless of the load (at normal air pressure in the tires).
