Why does the steering wheel shake left and right on bumpy roads?

[AubreeMarie]

When driving on bumpy roads, it is normal for the steering wheel to sway left and right. Here is the relevant information: 1. The steering wheel sways left and right on bumpy roads because the uneven road surface reacts on the tires, which then transmits through the wheel hub, steering axle, steering linkage, power assist mechanism, steering column, and other steering components, causing slight rotation or vibration of the steering wheel. 2. Due to extreme road undulations, the steering wheel will sway left and right along with the tire movement. The safest way is to hold the steering wheel with your fingers following its direction. Avoid placing your fingers on the inner side of the steering wheel or gripping it inversely to prevent injury to your fingers or wrists.
