What Causes Car Wobbling?

[NolanLee]

Car wobbling can be attributed to several factors from the perspective of wheel balance: Wheel imbalance is a common issue in many vehicles. During manufacturing, tires and rims cannot guarantee perfectly uniform quality, and worn tires may lead to rotational imbalance, subsequently causing body sway. From the perspective of steering gear clearance: Over time, the meshing gears and racks wear out, creating play between them, which results in a sensation of body wobbling. From the suspension framework perspective: Suspension components are connected via ball joints and rubber bushings. However, as these ball joints and bushings wear out, the components may loosen, leading to a loose suspension system that causes body wobbling during driving.
