Why does the front left wheel of the Geely Geometry C make abnormal noises when passing over bumps?

[JayceAnn]

The reason why the front left wheel of the Geely Geometry C makes abnormal noises when passing over bumps is due to deformation of the subframe. Effects of subframe deformation: Minor deformation of the subframe is a relatively serious issue. If the subframe is deformed, the wheel alignment data will be affected, which in turn impacts the vehicle's handling and driving stability. Function of the subframe: The subframe can be considered as the skeleton of the front and rear axles, forming part of their structure. The subframe is not a complete chassis but rather a bracket that supports the front and rear axles and suspension, connecting them to the "main frame," hence commonly referred to as the "subframe." The purpose of the subframe is to block vibrations and noise, reducing their direct transmission into the cabin. Therefore, subframes are mostly found in luxury sedans and SUVs, with some vehicles even equipping subframes for the engine. In traditional unibody designs without subframes, the suspension is directly connected to the body panels.
