What is the problem with the abnormal noise from the car chassis?

It may be an issue with the suspension system. Here is an introduction about the chassis: Introduction: The chassis refers to the combination of the transmission system, running system, steering system, and braking system in a car. 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. Function: 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, and receiving the engine's power to make the car move and ensure normal driving. At the same time, a good chassis can ensure the driver's life safety.
Having driven for decades, the annoying noises from a car's chassis are usually due to suspension system issues, such as aging or leaking shock absorbers that creak on bumpy roads; loose tie rods or ball joints that produce clunking sounds when turning; loud noises during braking might indicate grooved brake discs or unevenly worn brake pads; worn universal joints on the driveshaft can also cause clicking sounds during acceleration or deceleration. Loose chassis bolts are even more common, especially in older cars where the rattling is noticeable on rough roads. I believe these problems should be addressed early; otherwise, the car may become shaky and unstable, compromising driving safety. It's best to have mechanics tighten bolts and inspect rubber components during regular maintenance, rather than waiting for a breakdown and regretting it later.
As a young driver, I'm most annoyed by the clunking noise from the chassis during long-distance drives, always worrying about potential accidents. The mechanic buddies told me that broken shock absorber springs produce screeching sounds, while faulty wheel bearings create a humming noise when driving straight. If there's loud noise during gear shifting, it's likely due to gaps in the driveshaft or differential. Loose exhaust system pipes hitting the frame make even more noticeable sounds. They recommended I first check tire pressure and wear patterns to avoid alignment issues causing extra noise, then take the car to a professional shop for a full scan. Simple maintenance may cost some money but brings much more peace of mind – never underestimate the importance of safe driving.
