How to Solve Steering Wheel Vibration at 120 km/h on Highway
2 Answers
Solutions for steering wheel vibration at 120 km/h on highway: Perform four-wheel alignment and dynamic balancing for the car tires, and replace the tires if the situation is severe. Wheel dynamic imbalance is a common cause of steering wheel vibration. Once the wheel dynamic balance is off, radial wheel vibration will occur during driving, which transmits to the steering wheel through the steering mechanism, causing the steering wheel to vibrate. There are many reasons for wheel dynamic imbalance, including the detachment of balancing weights, tire repairs, excessive wheel rim repairs, or a large amount of mud inside the wheel rim. Other causes of steering wheel vibration at high speeds include inconsistent tire pressure, which can also lead to reduced braking efficiency, difficulty in steering, or heavy steering. Prolonged driving under such conditions will shorten the tire's service life, increase the risk of tire blowouts, and raise fuel consumption.
A few days ago, I was driving on the highway at 120 km/h when the steering wheel started shaking violently, so I quickly pulled over to check. This situation is usually caused by unbalanced tires, possibly due to deformed rims or uneven tire wear. When I last went to the tire shop for wheel balancing, the technician explained that if the tire pressure is insufficient or the wheels are not round, the shaking can be severe. They also suggested checking the suspension system for aging components, such as loose ball joints, which can also affect stability. The solution is quite simple: first, ensure the tire pressure is correct and the wear is even. If everything seems fine, schedule a wheel balancing adjustment—that should usually fix the problem. If the rims are severely deformed, they might need replacement. Don’t take it lightly—highway shaking is extremely dangerous and can easily lead to loss of control. Safety should always come first.
