What Causes Vibration When Braking Above 80 km/h?

[AlanaLynn]

When braking at speeds exceeding 80 km/h, the steering wheel may vibrate due to the following five reasons. 1. Tire deformation or vehicle drivetrain issues: If the steering wheel shakes when driving between 80 km/h and 90 km/h but returns to normal above 90 km/h, this is mostly caused by tire deformation or drivetrain problems. Check the front wheel alignment angles and toe-in to ensure they meet specifications—adjust if necessary. Lift the front axle and rotate the wheels to inspect their static balance and check for excessive tire deformation. Replace the tires if deformation is found. 2. Worn or loose ball joints or detached rubber bushings: If the vehicle drives smoothly on flat roads but the steering wheel shakes on rough surfaces, this may be due to worn or loose ball joints, detached rubber bushings, or irregular tire wear from excessive use. Take the car to a professional repair shop for inspection and replace any damaged components.
