Modification notes
| Checking | ||
1 | Note general information on chassis alignment | ||
2 | Measure vehicle level at front and rear axles with electronic inclinometer | ||
3 | Perform wheel alignment check | During the chassis alignment the actual chassis data such as camber (α), toe-in and caster (τ), are determined irrespective of the vehicle level. | |
4 | Check camber (α) using vehicle level and match with value in table | Use the measured vehicle level to look up the specified values for the camber (α) on the table sheet and note down these values. Compare the specified values of camber (α) with the actual values from the chassis measurement. If the measured value deviates, adjust the camber (α). | |

5 | Check caster (τ) via the vehicle level and assign tabular value | The caster (τ) cannot be adjusted but it must be checked to verify the correct chassis geometry. | |

6 | Adjust camber (α) according to table value | Replace cam bolt (1), collar bolt (2) and nuts if not already replaced during the previous operations. To replace the cam bolt (1) and collar bolt (2) lift up the respective axle half. | |
Set the camber (α) to the specified value using the cam bolt (1) and then tighten the cam bolt (1) and collar bolt (2). To facilitate the torque angle, lift up the respective axle half. | |||
