What Causes Steering Wheel Vibration at 100 km/h on the Highway?

[DelSamantha]

Steering wheel vibration at 100 km/h on the highway may be caused by car idling or steering wheel malfunction. Below is a detailed explanation of the reasons for steering wheel vibration at 100 km/h: 1. Car idling: Steering wheel vibration during car idling is relatively common. Uneven mass distribution across various parts of the tire can cause wheel imbalance during high-speed rotation, leading to severe steering wheel vibration while driving. In such cases, a four-wheel alignment is necessary, and in severe cases, the tires may need to be replaced. 2. Other causes: Apart from tire-related issues, potential causes include shock absorber failure, frame deformation, excessive clearance in the main reducer's gear meshing, etc. If the steering wheel vibrates during braking while driving, it is likely due to a steering wheel malfunction. In this scenario, the brake discs and brake pads should be replaced. If steering wheel vibration occurs at lower speeds, it might be due to mechanical steering system issues, such as a loose steering gear belt causing slippage, which can also lead to steering wheel vibration.
