What Causes Steering Wheel Vibration at 120 km/h?

[RubyLee]

Here are the specific reasons for steering wheel vibration when braking at 120 km/h: 1. Wheel Balancing Issue: A car wheel consists of a tire and rim. When there's a wheel balancing problem, it means the wheel isn't in a balanced state during high-speed driving. If the balancing data is incorrect, the wheel's rotation center will shift, causing vibration that transmits to the steering wheel. 2. Rim Problem: If the rim has previously suffered impact damage leading to deformation, this can also cause wheel vibration during driving, resulting in steering wheel shake. 3. Chassis Component Issue: This typically occurs in poorly repaired post-accident vehicles. Impact damage to chassis components during collisions can also cause steering wheel vibration.
