Which noise might indicate an issue with CV joints?

When diagnosing issues with constant velocity (CV) joints, the presence of clicking or popping noises is a strong indicator of potential problems. This sound typically occurs when the vehicle is making sharp turns or when the suspension is under load. CV joints are designed to allow for the flexibility needed during such maneuvers while transmitting engine power to the wheels.

The clicking or popping noise is often caused by wear and tear on the CV joint’s internal components, such as the bearings or cages, which can result in a loss of smoothness during operation. As these components degrade, they may not function properly, leading to the characteristic sounds that alert a technician to inspect the joint further.

Other noises like hissing, whirring, rattling, or clattering may indicate different mechanical issues unrelated to CV joints, such as problems with bearings or other drivetrain components. Squeaking or squealing sounds might come from issues related to brakes or suspension rather than the CV joints themselves. Thus, recognizing clicking or popping as the specific noise associated with CV joint problems enables a technician to focus their diagnostic efforts effectively.
