What Causes Steering Wheel Vibration in Cars?
2 Answers
Steering wheel vibration in cars is mainly caused by loose tie rod ends or abnormal braking. Loose Tie Rod Ends: When driving, if the tie rod ends are loose or the rubber bushings at the joints are detached, and the tires become irregular due to wear, the car should be sent to a professional repair shop for inspection and replacement of damaged parts. The vehicle may drive normally on smooth roads, but the steering wheel may vibrate when encountering rough or uneven surfaces. Abnormal Braking: Excessive or frequent braking can cause the brake discs and brake pads to overheat and deform when cooled, leading to steering wheel vibration. Generally, replacing the brake discs and brake pads can resolve this issue.
I used to experience steering wheel vibration frequently when driving long distances. The most likely cause is tire imbalance, such as missing balancing weights or uneven tire wear, which is most noticeable at speeds between 60-80 km/h. The vibration is not only uncomfortable but also dangerous. It could also be due to loose suspension components, like worn-out shock absorbers or control arms, which can cause wheel instability. I remember once on the highway, the steering wheel shook so violently I could barely hold onto it. A later inspection revealed the tires needed rebalancing. I recommend getting your tires balanced and the suspension checked by a professional every 10,000 km, along with rotating the tires to prevent uneven wear. When driving, try to maintain a steady speed—sudden acceleration or deceleration can trigger vibrations and compromise safety. Additionally, warped rims or underinflated tires can also contribute to the problem, so checking tire pressure regularly can help prevent issues.
