Why Does the Steering Wheel Start to Shake at 80 km/h?
1 Answers
The possible causes for this issue may include wheel alignment, tire dynamic balance, friction coefficient of new tires, improper installation of chassis components during repair, and deformation of front bearing balls. Below are the reasons and solutions for steering wheel shaking in cars: 1. Steering wheel shaking when encountering bumpy roads: While driving, if the tie rod ball joint is loose or the rubber sleeve at the joint falls off, or if the tires become irregular due to wear, the car should be sent to a professional repair shop for inspection and replacement of damaged parts. 2. Sudden steering wheel shaking during high-speed driving: Excessive or frequent braking may cause the brake discs and brake pads to overheat and deform when cooled, leading to steering wheel shaking. Generally, replacing the brake discs and brake pads can resolve the symptoms. 3. Steering wheel shaking when stationary: Many car owners solve this by increasing the idle speed or lightly pressing the accelerator during startup to raise the RPM and avoid resonance points of the body, steering, and transmission components. Some older cars develop shaking over time, mainly due to aging of engine mounts and rubber components at connections. Replacing the corresponding parts usually solves the problem. 4. Shaking when turning the steering wheel: Shaking when turning the steering wheel may be caused by the timing belt being too loose or too tight. This issue often occurs in vehicles with hydraulic power steering. While not a major problem, it still requires timely repair.
