Why does your steering wheel shake as well as your engine while in idle when you turn the steering wheel?

A shaking steering wheel and engine while idling can indicate issues with the engine mounts or the Power Steering system. Worn or damaged engine mounts can cause excessive vibration to transfer to the steering wheel, especially when the engine is under load. Additionally, low power steering fluid or a failing power steering pump can lead to erratic steering responses, contributing to the shaking sensation. It's important to have these components inspected to ensure safe and smooth vehicle operation.
