Remedy:
The complaint must be reproduced by means of a test drive.
If it is not possible to reproduce the complaint, contact the customer. Otherwise, process the following points one after
the other.
1) Check wheels for damage and tire inflation pressure. Replace any damaged, unusable wheels. Correct the tire inflation pressure. Perform a test
drive if the deviations are greater than 0.5 bar.
2) Check radial force variation (RFV) of the front wheels on a suitable balance machine. Match mount the wheels/tires if necessary.
3) Balance wheels on wheel balancing machine.
4) Mount the wheels. Ensure that they are seated centrally and tighten the wheel studs/wheel nuts finger-tight in a crosswise pattern, then tighten to
