What sounds indicate early-stage damage to a car's CV joint?

[SanEli]

When a vehicle emits metallic friction sounds or metallic collision sounds, these are characteristic signs of early-stage damage to the CV joint. The symptoms of a damaged car half-shaft are as follows: Vehicle pulling to one side: Since the half-shaft functions as a rotating axle, if the transmission system of the upper and lower half-shafts is damaged, the car's steering wheel may deviate. Abnormal noises when turning the steering wheel: Due to half-shaft damage, the vehicle's rotational balance will be compromised, significantly affecting driving stability and causing abnormal noises when turning the steering wheel. Uneven tire wear: Prolonged half-shaft damage can lead to uneven tire wear, resulting in cracks and accelerated wear. Tire detachment: If the half-shaft is severely damaged, the tire may detach while driving, leading to potentially catastrophic traffic accidents.

I've been driving for over ten years and encountered this issue before. In the early stages of a car's CV joint (constant velocity joint) damage, you'll hear a continuous rattling sound when accelerating during turns, somewhat like the noise of a stone stuck in the wheel. This sound is most noticeable during slow turns or when reversing and steering. Initially, the noise isn't loud, but if ignored, it will become louder and more frequent, potentially leading to a complete CV joint fracture and sudden vehicle breakdown. I remember during one repair visit, the mechanic explained that this happens due to wear and tear of the ball bearings inside the CV joint, causing friction and noise during rotation. It's advisable to get it checked at a professional shop as soon as you hear such abnormal sounds. The repair isn't expensive—replacing the CV joint can solve the problem. To prevent premature damage, try to avoid sharp turns and driving on bumpy roads during daily driving.

Having worked in the auto repair shop for a long time, I've heard this sound too often. When the CV joint starts to wear, it produces a rhythmic clunking noise during acceleration while turning, resembling a clicking or knocking sound, which becomes more noticeable during low-speed cornering. The cause is usually internal wear of the ball bearings or grooves in the universal joint, creating friction and abnormal noise under load. If ignored, the noise will intensify, and once the joint loosens, the axle shaft may detach, posing a risk of losing control of the vehicle. For a simple self-diagnosis: lift the car and shake the wheel—if there's looseness or a creaking sound, it's time for repairs. Replacing the CV joint early costs just a few hundred yuan, so don't wait until the entire axle shaft is ruined before taking action.

I'm a new driver, and recently I've been hearing a rattling sound when turning. A friend told me it might be a sign of a bad CV joint. Initially, the sound was very faint and only occurred when accelerating during turns, disappearing at other times. After researching online, I found that it could be due to wear and tear causing increased internal friction. If left unrepaired, the noise could get louder and might even affect the car's safe operation. I think it's best to visit a repair shop to get it checked out before a small issue turns into a big problem.
