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.
