Wheel Alignment Preparations
Wheel Alignment Preparations
Special tools, testers and auxiliary items required
• Wheel alignment computer (V.A.G 1813F) or VW/Audi approved alignment equipment
• Brake pedal actuator (V.A.G 1869/2)
• Insert tool 18 (T10179)
• Shock absorber set (T10001)
The lateral run-out of the wheel must be compensated for. Otherwise, measurement will result in false readings.
A correct toe-in adjustment will not be possible without performing lateral run-out compensation!
Follow the operating instructions provided by the manufacturer of the alignment equipment.
- Perform wheel run-out compensation.
- Insert brake pedal actuator (V.A.G 1869/2).
- Actuate the brake pedal using brake pedal loading device.
If the measured values are outside the allowed tolerances, the cause may be an incorrect vehicle attitude.
Right-hand drive vehicles or for example vehicles with automatic transmission can lean to one side slightly.
This is due to the installation position of the assemblies and the corresponding weight transfer and is normal.
- It is absolutely necessary to measure dimension - a - on left and right sides.
- Correct any 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 example, sand bags of approximately 10 kg are suitable as weights.
