The rear suspension to independent wheels with longitudinal arms offers the advantage of being significantly reduced in size thereby enabling the adoption of a particularly low and wide luggage compartment. The inherent problem with this type of suspension is that the wheels vary their inclination following the rolling of the vehicle.

This has been solved through the adoption of a stabilizer bar integral with the longitudinal arms. The rear suspension assembly can be broken down into the following main components:

• Rear rigid axle (5), in tubular sheet metal, fastened to the body through flexible plugs (3).
• Longitudinal arms (2) integrated with the axle by screws and hinged on taper roller bearings (9). They support the wheel hub (4) and part of the braking system.
• The stabilizer bar (6) connected to the longitudinal arms limits the transversal lean of the car and by its own rotation also controls the operation of the braking load proportioning valve (7) which is connected to it.
• Helical springs (1) which limit the thrust on the shock absorber stem.
• Shock absorbers (8) which are pressurized with lamellar inlet valves that warrant a high degree of riding comfort.

SHOCK ABSORBERS

REMOVAL/REFITTING

• Set the car on a lift.
• Remove the wheel on the side concerned.

1. Raise the car and using a hydraulic jack placed under the longitudinal arm, preload the spring.
2. Slacken the lower nut fastening the shock absorber to the suspension longitudinal arm.
