I stopped by with a vibration problem after 90 km/h. The front wheels were removed and balanced, 20p was stripped off. Ideally, the rubber jumps slightly. They offered to rock the wheels to 3.5 atmospheres and travel 400 kilometers. Shake your head the next time you suggest something like that to someone. The wheels were clamped almost with a cargo wrench and squeezed with a crank from above, there is no talk of any torque wrench or tightening torque. Some underage amateurs are working. I'm not happy with my job. No one even came up to the rear axle and looked at it. At the next service station, the master just took a look at the wheels and told them to clean the dirt, everything was as he said. The discs were cleaned and the vibration went away . No customer orientation.
