What is wheel shimmy?

Wheel shimmy refers to a vibration or oscillation felt through the steering wheel, often caused by an imbalance in the wheels or misalignment of the vehicle's suspension components. This phenomenon typically occurs at certain speeds and can be a result of issues like worn tires, improper wheel balancing, or damaged suspension parts. If left unaddressed, wheel shimmy can affect vehicle handling and safety, making it important to diagnose and rectify the underlying cause.
