What Causes Steering Wheel Shaking on the Highway?
1 Answers
When a car's steering wheel shakes during high-speed driving, it can be attributed to the following reasons: 1. Overheating of the brake discs or brake pads, which deforms upon cooling, causing the steering wheel to shake. Frequent braking or excessive braking force can lead to this issue. It typically manifests as sudden shaking during high-speed driving. Solution: Replace the brake discs and brake pads. 2. Problems with the transmission system. This usually appears as steering wheel shaking at speeds between 80 km/h and 90 km/h, with normal operation resuming above 90 km/h. Solution: Lift the front axle and test the wheel rotation. If misaligned, adjust it; if the tire deformation is excessive, replace it. 3. Inconsistent tire pressure among the four tires or abnormal tire pressure. Solution: Identify and address the cause, then replace the tires if necessary. 4. Issues with wheel alignment. The most common problems involve changes in alignment parameters such as toe angle, camber angle, kingpin inclination angle, and caster angle. Solution: Perform a four-wheel alignment again. 5. Disruption of wheel dynamic balance. Changes in tire weight distribution, such as uneven tire wear or wheel hub deformation, can disrupt the dynamic balance. Solution: Rebalance the wheels.
