What Causes Steering Wheel Shaking During Normal Driving?
2 Answers
Steering wheel shaking during normal driving can be caused by issues with the tires, engine mounts, or excessive speed. Below is an introduction to steering wheels: 1. Overview: The steering wheel is a wheel-shaped device used to control the direction of vehicles such as cars, ships, and airplanes. 2. Function: The steering wheel converts the force applied by the driver on its edge into torque, which is then transmitted to the steering shaft. It mainly consists of a frame, foam, and mounting clips or screw holes corresponding to the driver's airbag (DAB). 3. Structure: Steering wheels are generally made of zinc alloy or aluminum alloy. Some manufacturers are experimenting with cheaper and lighter magnesium alloys. The frame is produced through die-casting. A few manufacturers still use steel sheet metal for the frame, which results in a more complex structure.
I've encountered steering wheel vibration issues several times, usually related to tires. The shaking is particularly noticeable at highway speeds, most likely caused by improper tire balancing. When wheels rotate at high speeds, any imbalance gets transmitted to the steering wheel. Additionally, uneven tire wear or bulges can also cause vibrations, which become especially noticeable during hard braking. Suspension system problems are another common cause, such as loose lower control arm ball joints or failed shock absorbers. Steering gear failure can also make the steering wheel shake, though this usually comes with abnormal noises. If you can't identify the cause, remember to check if the brake discs are warped - especially if the steering wheel shakes after hard braking, there's an 80% chance it's a brake disc issue. I recommend going to a repair shop for inspection immediately, as safety should always come first.
