

Check

1

Check preconditions for wheel alignment.

AR40.20-D-0050TS

2.1

Determine front-axle level using the transverse control arm angle bracket with electronic inclinometer.

When measuring with electronic inclinometer.

AR40.20-D-6870TS

2.2

Determine front-axle level through actual front-axle load.

When measuring without electronic inclinometer.

 Commercially available devices/tools
Wheel load scales

3

Perform chassis alignment.

AR40.20-D-0200TS

4

Check gear ratio spread via vehicle level and assign tabular value.

 Use the measured vehicle level to look up the specified values for the steering axis inclination on the table and note down these values. Compare the steering axis inclination specified values according to the vehicle level with the actual values measured during the wheel alignment check.
The gear ratio spread cannot be adjusted, but it must be checked to ensure the suspension geometry is correct.
