What Causes Slight Steering Wheel Vibration When Touched?

[CarsonFitz]

Slight steering wheel vibration when touched is caused by poor engine smoothness or faulty engine mounts. There are engine mounts at the connection points between the engine and the frame, typically made of rubber, which prevent engine vibrations from being directly transmitted to the vehicle body, thereby improving ride comfort. Over time, rubber components can age, harden, and even crack. When the engine mounts deteriorate, engine vibrations will transfer to the body, resulting in slight steering wheel vibration when touched. Some engines naturally have less smooth operation and may produce slight vibrations during operation, which is normal.
