What Causes the Clunking Sound from the Chassis When Starting the Car?

Car starting with a clunking sound from the chassis may be due to aging chassis components. Here is an introduction about the car chassis: Introduction: The chassis refers to the combination of the transmission system, running gear, steering system, and braking system on a car. Function: It supports and installs the car engine and its various components and assemblies, forming the overall shape of the car, bearing the engine power, and ensuring normal driving. Related functions: The role of the chassis is to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power to make the car move and ensuring normal driving.
When I start driving, there's a clunking sound from the chassis. I've encountered this issue a few times before, usually caused by wear or looseness in chassis components. For example, the ball joints in the suspension system may have become loose, or the shock absorbers aren't securely fixed, leading to stress concentration and noise during gear shifting when starting. It could also be a problem with the brake system, where the brake calipers or drum brakes aren't gripping tightly, causing a noise when the vehicle moves. Sometimes, it's due to wear in the drive shafts, especially common in older cars. I suggest you pay more attention to your car's condition and not delay until major problems arise. Once you hear the noise, it's best to have it checked at a professional repair shop. You could also try tightening it with a wrench yourself, but improper handling might compromise vehicle safety. Early repairs ensure peace of mind.
