Complete suspension - general - GF32.00-P-9611-01I

General 

The vehicle has a new, fully-supporting air suspension system on the front and rear axle which offers a soft basic suspension with a low natural frequency. In addition the full spring travel is always available when the vehicle is laden.

Components: 

• Spring struts with integrated ADS II shock absorbers
• Compressor (maintenance-free)
• Central reservoir
• Level control valve unit
• Polyamide pressure lines (connectors guarantee easy replacement)

The spring strut  (40) on the front axle is attached at the bottom to the spring link (17) via two stud bolts (40c) on the ball joint and attached at the top to the body by three nuts (40b).The pressure line is connected to the residual pressure valve (40a).

The spring strut  (41) on the rear axle  is connected at the bottom with spring link (72). The upper suspension is accessible after the cover (arrow) in the rear-window shelf is removed.

The compressor unit for air suspension  (A9/1) is attached on the bottom right of the longitudinal member.

The level control valve unit  (Y36/6) is flange-mounted to it.

The central reservoir  (42) is located on the left-hand side of the body.

General notes on air suspension 

• For removal, the particular unit is to be depressurized using the Star Diagnosis tool.
• Do not drain any compressed-air via the pipe connection as the compressed-air normally flows back through the air drier, regenerating the desiccant.

Also refer to function description of air suspension.

Torsion bars 

The rubber mounts for the torsion bar mount are vulcanized on the torsion bar at the front and rear axle, reducing torsion bar noise. Both torsion bars are made of solid material.

The front axle torsion bar  (arrow) is mounted on the front axle carrier and, via the connecting rod (23), is connected to the spring link (17) via a ball joint.

The torsion bar at the rear axle  is located on the rear axle carrier as on model 140.
