Why is the steering wheel shaking?
2 Answers
Reasons for car steering wheel shaking are as follows: 1. Toe-in: Due to collisions during driving, the steering tie rod and steering cross rod may deform, various ball joints may wear out and become loose, or tire wear may become irregular, causing the toe-in to increase or decrease. 2. Wheel dynamic balance: After driving a certain mileage, the original wheel dynamic balance lead weights may be lost, or the wheel hub may deform. When driving at high speeds, the front of the car may sway, and the steering wheel may shake. 3. Push rod: Loose transverse push rod ball joints or loose supports may cause instability during car driving. 4. Wheel hub bearing: Loose wheel hub bearings and severely worn left and right steering knuckle ball joints may cause inaccurate front wheel alignment. 5. Steering shock absorber: When the car is driving, a damaged or leaking steering shock absorber, or deformed front suspension springs may also affect the car's stability.
I've encountered steering wheel shaking several times while driving. The most common cause is tire imbalance, especially noticeable when the speed exceeds 80 km/h, which is usually caused by uneven tire wear or slight deformation of the wheel hub. Another possible factor is uneven brake discs, causing severe steering wheel vibration during braking. My old car had this issue before and needed brake disc replacement. Loose suspension systems or aging steering components can also lead to shaking. Once, I felt steering wheel vibration on bumpy roads due to this problem. In any case, steering wheel shaking shouldn't be ignored as it affects driving stability and safety. I recommend going to a tire shop or repair shop for a four-wheel alignment and tire balance check as soon as possible to avoid bigger troubles.
