Steering Wheel Vibration at Speeds Above 80 km/h

[DiLilliana]

This situation occurs due to poor gasoline combustion and excessive dirt on the throttle body, which causes engine vibration that is transmitted to the steering wheel. Solution: Visit a repair shop to check if the throttle body is excessively dirty. If necessary, clean and inspect the bottom-related automotive components. Perform wheel dynamic balancing again. The only solution when the steering wheel vibrates slightly when braking at speeds above 80 km/h: Perform wheel dynamic balancing again. The dynamic balance of wheels and tires is extremely delicate yet crucial. If any issues are detected, the following checks must be performed: First, inspect the balance weights on the wheels. If the balance weights are missing or have fallen off, it will mostly cause steering wheel vibration. After installing new balance weights, ensure that both longitudinal and lateral vibration amplitudes are less than 0.3 mm. Additionally, since the front wheels are steering wheels, the requirements for wheel dynamic balance are extremely stringent.
