What Causes Steering Wheel Vibration?
2 Answers
Steering wheel vibration can be divided into two scenarios: 1. Vibration at idle speed, which is relatively mild and not intense. The primary causes are usually loose steering wheel bolts or rubber bushings. 2. The other type occurs during driving, particularly at higher speeds. This type of vibration is typically caused by dynamic imbalance. When there is a dynamic imbalance issue, the tire will exhibit imbalance and bouncing during rotation. Since the steering wheel is connected to the tires, this bouncing force is transmitted through the drive shaft to the steering wheel, resulting in vibration. Therefore, steering wheel vibration serves as a signal of abnormal vehicle dynamic balance.
As someone who has driven countless mountain roads, I can tell you that steering wheel vibration is mostly caused by tire issues. For example, if the tires are unbalanced, the uneven weight distribution when the wheels rotate can cause constant shaking at speeds above 60 km/h, making it very uncomfortable to hold the wheel. Deformed rims are also a common culprit, especially if your car frequently drives over potholes or has hit curbs. Additionally, if the brake discs are worn or warped, the steering wheel may suddenly shake like it's dancing when you apply the brakes. All these issues threaten safety, so it's crucial to visit a repair shop immediately for a dynamic balance check or part replacement. The longer you drive at high speeds with these problems, the higher the risk of an accident—don't ignore them.
