What are the causes of car steering wheel vibration?
2 Answers
The causes of car steering wheel vibration: 1. Due to collision during driving, the steering tie rod and steering cross rod are deformed, various ball joints are worn and loose, or tire wear is irregular, causing the toe-in to increase or decrease; 2. After driving a certain mileage, the original wheel dynamic balance lead block is lost, the wheel hub is deformed, and when driving at high speed, the front of the car shakes and the steering wheel vibrates; 3. The transverse push rod ball joint is loose or the bracket is loose, causing instability during driving; 4. The wheel hub bearing is loose and the left and right steering knuckle ball joints are severely worn, causing inaccurate front wheel alignment; 5. When the car is driving, the steering shock absorber is damaged and leaking oil, or the front suspension spring is deformed, which also affects the stability of the car.
I've seen quite a few cases of steering wheel vibration. The most common cause is tire imbalance, which simply means the weight distribution is uneven when the wheels rotate, causing the steering wheel to shake at high speeds. Another cause could be deformed or damaged rims, like when a wheel gets bent after hitting a curb, leading to vibration. If components in the suspension system are worn out, such as aging lower control arms or shock absorbers, the steering wheel may also vibrate when the car goes over bumps. Brake system issues shouldn't be overlooked either; warped or rusted brake discs can cause the steering wheel to shake when braking. My advice is to start by checking the tires—get them balanced or replaced if necessary. If the problem persists, then inspect other components to prevent more serious failures that could affect safe driving.
