Why does the steering wheel shake left and right at 120 km/h?
2 Answers
The reasons for the steering wheel shaking left and right at 120 km/h are as follows: Common causes: The most common reason is that the tires and rims need wheel balancing. Or the tires may be aged and deformed, or the rims may be deformed. Wheel balancing can be performed based on the situation. During wheel balancing, be sure to check the condition of the tires and rims, and replace any deformed parts. Other causes: The engine fault light is already on or suddenly turns on. If the engine fault light is already on or suddenly turns on, accompanied by body shaking. This situation is caused by improper engine air-fuel mixture matching. Common problem areas include spark plugs, ignition coils, fuel injectors, carbon deposits, fuel pumps, etc.
I experienced severe steering wheel shaking while driving, feeling as tense as driving on a washboard. Common causes include wheel imbalance, such as improper tire installation or uneven air pressure, leading to vibrations at high speeds. It could also be due to uneven tire wear or slight wheel hub deformation. Additionally, aging suspension components like failed shock absorbers can amplify the shaking. It's recommended to visit a repair shop promptly for a tire dynamic balance check, which is affordable and typically costs around a hundred yuan. Regular maintenance should include checking tire pressure and wear patterns to prevent cumulative issues. Ignoring this poses significant risks—high-speed shaking compromises control and increases accident probability. Safety comes first; don't wait for an incident to address it.
