What is the reason for the gap when lifting and shaking the front wheels of a car left and right?

[StKeira]

Lifting the front wheels of a car and shaking them left and right with a gap is due to loose ball joints. The following are specific symptoms of damaged ball joints in a car: 1. Abnormal noise: The car will make abnormal noises when driving on bumpy roads. If the car frequently drives on rough road conditions, the lifespan of the ball joints will be relatively shorter, and they may get damaged within 30,000 to 40,000 kilometers. 2. Vibration: You can clearly feel the vibration of the wheels when driving at low speeds. 3. Unstable driving: The car becomes unstable during driving, showing signs of swaying left and right or pulling to one side. In severe cases, it may even lead to brake failure. 4. Prone to breaking: If the play in the ball joints is too large, they are more likely to break under impact loads.
