Which of the following can indicate the need for CV joint replacement?

A clicking noise during turns is a classic symptom that suggests a potential issue with the CV (Constant Velocity) joints in a vehicle. The CV joint is essential for transferring power from the drivetrain to the wheels while allowing for up-and-down motion of the suspension and side-to-side movement of the front wheels when turning. When the CV joints begin to wear out, especially the outer joints, they can produce a clicking or popping noise, particularly noticeable during sharp turns.

This noise occurs due to the joint's increased play or damaged components that are unable to maintain a smooth rotation, which is crucial during turning maneuvers. Therefore, the presence of clicking noises is a clear indication that it may be time for a CV joint replacement to maintain safe and efficient vehicle operation.

In contrast, symptoms such as vibration at high speeds, brake pedal pulsation, and unusual tire wear may point to a variety of other issues unrelated to the CV joints, such as wheel balancing, brake system problems, or alignment issues. Hence, while those symptoms might indicate other mechanical concerns, clicking noises during turns are distinctly related to CV joint failure.
