Is it necessary to replace the CV joint if it makes noise?

If the CV joint is making noise solely due to lack of lubrication, you can try applying lubricant inside the CV joint. If the noise disappears and the CV joint operates smoothly afterward, replacement is unnecessary. However, if the CV joint is severely worn and the external rubber component is completely damaged, the CV joint should be replaced. There are two common types of CV joints used in passenger cars: 1. Fixed-type CV joint: Its characteristic is that it only allows relative rotation between the driving and driven shafts during torque transmission without axial displacement. It is typically used near the wheel, commonly referred to as the outer CV joint. 2. Sliding-type CV joint: Its characteristic is that it not only allows relative rotation between the driving and driven shafts during torque transmission but also permits axial displacement. It is usually used near the drive axle, commonly known as the inner CV joint.

I just bought the car not long ago and noticed a clicking sound when turning. Upon inspection, it turned out to be a CV joint noise issue. This kind of noise indicates wear in the CV joint, which is a key component responsible for power transmission. If left unreplaced, the wear will worsen, leading to joint failure. During turns, the vehicle may lose control or even roll over, posing significant safety risks. So yes, it must be replaced. I later went to a repair shop for confirmation, and after replacing the new CV joint, the problem was resolved. The cost ranges from 500 to over 1000 yuan, depending on the car model. Don’t risk a major accident to save a small amount of money. Pay attention to steering sounds regularly and perform routine maintenance to check if the oil seal is leaking to avoid dry friction. As a new car owner, safe driving is the top priority—take immediate action if you hear any unusual noises.

I've been in the auto repair industry for over a decade, and encountering CV joint noise is all too common. Those clicking sounds are loudest when turning, usually indicating lack of lubrication or damage in the CV joint. It must be replaced immediately—otherwise, wear spreads, the driveshaft seizes up, and repair costs double. I recommend owners visit a professional shop for diagnostic tool testing and replace the part once confirmed. Those with strong DIY skills can use specialized tools, but since it involves steering and suspension systems, it's risky—ordinary folks shouldn't take the chance. Routine maintenance shouldn't overlook inspecting the oil seals; regular lubrication extends lifespan. After replacement, drive a few thousand kilometers to test for quiet, stable operation. Safety is no small matter—address any noise immediately; never delay.

I've been driving trucks for half my life and have seen countless cases of CV joint noise. In the past, any strange sound when turning meant the CV joint was about to fail and needed immediate replacement. If not replaced, the tires would slip during steering, which is extremely dangerous on highways. Veteran driver experience proves that delaying replacement increases accident risks. Although modern technology makes parts more durable nowadays, CV joints should still be replaced as soon as noise appears. The simple solution is to find a reliable auto shop to handle it - spend a little money to ensure safety. During daily driving, remember to slow down when turning to reduce stress on the steering system. Always prioritize safety - unusual noises are warning signals that demand immediate action.
