What are the reasons for steering wheel vibration when driving a car?

The reasons for steering wheel vibration when driving a car are: 1. Incorrect front wheel alignment angles, excessive toe-in; 2. Low front tire pressure or unbalanced tires; 3. Deformed front wheel hubs or unequal number of tire bolts; 4. Loose components in the transmission system; 5. Bent drive shaft, dynamic imbalance, deformed front axle; 6. Faulty shock absorbers. The function of the steering wheel is to convert the force applied by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. The operation method of the steering wheel is: 1. Place both hands with appropriate force at the 9 o'clock and 3 o'clock positions of the steering wheel; 2. Naturally grip the steering wheel with four fingers inward and extend the thumbs naturally along the edge of the steering wheel.
When I drove my old car before, I experienced severe steering wheel shaking, which really startled me. There are several main causes: the most common is tire issues, such as uneven tire pressure or improper wheel balancing, leading to uneven rotation and causing the steering wheel to shake. Sometimes, significant tire wear or bulges can also cause this. The braking system might also be problematic, like warped brake discs or uneven brake pads, making the shaking more noticeable when braking. Another possibility is loose wheel bearings or worn ball joints, affecting the steering system. I believe safety comes first—when shaking occurs, it's crucial to get it checked as soon as possible, otherwise, losing control at high speeds can be dangerous. Regular maintenance, including tire balancing, checking tire pressure, and brakes, can effectively prevent such issues.
As a car enthusiast, I've done quite a bit of research on steering wheel vibrations. The root causes often point to tires and wheels: if you've changed rims without performing dynamic balancing, or if uneven road surfaces exacerbate the shaking. Vibrations during braking are mostly due to thermal deformation of brake discs or uneven wear. Additionally, aging suspension components can also cause issues, such as failed shock absorbers or loose control arms. Don't panic when encountering vibrations; first, pull over and slow down. Some cars naturally vibrate within specific speed ranges, especially between 60-80 km/h, and a four-wheel alignment can alleviate this. For prevention, I insist on checking tire wear and system fastenings every six months to ensure driving safety.
