Why Does the Steering Wheel Shake on the Highway?

[FelicityDella]

There are several reasons why the steering wheel shakes when driving at high speeds: 1. Overheating of the brake discs or brake pads, which deform when cooled, causing the steering wheel to shake. This can occur due to excessive braking frequency or overly aggressive braking. It typically manifests as sudden shaking during high-speed driving. Solution: Replace the brake discs or brake pads. 2. Issues with the drivetrain. 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 wheels. If misaligned, adjust them. If the tires are severely deformed, replace them. 3. Inconsistent tire pressure or abnormal tire pressure among the four tires. Solution: Identify the cause and replace the tires if necessary. 4. Problems with wheel alignment. The most common issue is changes in alignment parameters such as toe angle, camber angle, kingpin inclination angle, and caster angle. Solution: Perform a four-wheel alignment. 5. Disrupted wheel balance. Changes in tire weight distribution, such as uneven tire wear or wheel hub deformation, can disrupt wheel balance. Solution: Rebalance the wheels.
