Measurement process axle alignment

In accordance with state-of-the-art technology and the requirements of the vehicle manufacturers, the chassis geometry of the Opel/Vauxhall vehicles should be checked stet to the following values:

Rear axle geometry

• Individual toe and the resulting geometric driving axis
• Total toe
• Deviation of the geometric driving axis from the axis of symmetry
• Camber

Front axle geometry

• Straight-ahead position
• Individual toe to the geometric driving axis
• Total toe
• Toe variation
• Camber
• Castor
• Kingpin inclination
• Maximum angle of lock
• Wheel offset

To be able to determine all said values of the vehicle geometry, the 4-wheel alignment process is essential and prescribed for all Opel/Vauxhall vehicles since the introduction of the Vectra-B.

Other measurement processes which are no longer recommended for current vehicles are the simple 2-wheel alignment and 2-wheel alignment in relation to the axis of symmetry.

The measurement systems fall into four groups according to measurement method:

where only the electronic/mechanical combined measurement method is used for Opel/Vauxhall vehicles.
