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

[CalebAnn]

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.
