Does a noisy outer CV joint always need replacement?

[TaylorMarie]

Outer CV joint noise always requires replacement. If a CV joint produces abnormal noises, it indicates the joint is already damaged and needs repair or replacement. In the early stages of outer CV joint damage, the noise typically occurs only during turns but not when driving straight. Initially, the damaged CV joint only produces noise without affecting driving performance. However, if not repaired or replaced promptly, the condition will progressively worsen until the CV joint fails completely, rendering the vehicle inoperable. Therefore, timely replacement is recommended. Relevant information about CV joints is as follows: 1. Introduction: CV joint generally refers to a constant-velocity joint. A constant-velocity joint connects two shafts that have an angle between them or changing relative positions, allowing them to transmit power at the same angular velocity. It overcomes the unequal velocity problem inherent in ordinary cross-type universal joints. 2. Classification: The most widely used constant-velocity joints currently are mainly the ball-and-trunnion type and the Rzeppa (ball-and-cage) type.
