Measurement Preparations

Measurement preparations
Special tools, testers and auxiliary items required
^ Brake pedal depressor V.A.G. 1869/2

The lateral run-out of the wheel must be compensated for. Otherwise the result of the measurement will be incorrect.

If the lateral run-out compensation is not performed it is not possible to adjust the toe correctly!

When doing this observe the information from the manufacturer of the wheel alignment unit.
- Carry out wheel run-out compensation.
- Lower vehicle and bounce springs.
- Install brake pedal loading device V.A.G 1869/2.
- Actuate brake pedal with brake pedal loading device.

Vehicle trim height "Zero position"
Applies in principle!

If a value lies outside the tolerance, the vehicles trim height must be checked first.

If the measured values are outside the allowed tolerances, the cause may be an incorrect vehicle attitude.

Right-hand drive vehicles or vehicles with automatic transmission can lean to one side slightly.

This is due to the installation position of components and weight distribution





- It is absolutely necessary to measure dimension - a - on left and right sides.

The 0 line on the roof means the horizontal position (zero position) of the vehicle.
- Correct differences if necessary.

It is possible to correct trim height imbalance for front axle by adding weight to top of strut tower through the engine compartment.

To correct trim height imbalance for rear axle add weight to top of strut tower through the trunk compartment.

For weight sand bags are suitable for example, approximately 10 kg
