Why does the car still shake at 120 after multiple wheel balancing attempts?
1 Answers
There are two main reasons for steering wheel vibration when braking at high speeds of 120 km/h. Below are the relevant explanations: 1. Uneven brake disc wear: When brake discs wear unevenly, steering wheel vibration may occur during high-speed braking. When the vehicle reaches a certain speed and brakes, the left and right wheels on the same axle may experience asynchronous braking force moments within a rotation cycle, creating an uneven braking pattern. When this imbalance reaches a certain degree, it causes unequal rolling speeds between the left and right wheels, resulting in lateral wheel oscillation that transmits to the steering wheel. 2. Drivetrain malfunction: Steering wheel vibration during high-speed braking could also indicate issues with the vehicle's drivetrain. In such cases, it's advisable to inspect components like the tie rods and ball joints for signs of corrosion or looseness.
