Regarding CV joints, which statement is correct?

• A. A failed CV Joint can cause a clicking sound.
• B. The most common failure with CV Joints is torn or split boots.
• C. Both A and B
• D. Neither A nor B

Answer: (C)

CV joints rely on lubrication inside a protective boot to keep the bearing surfaces smooth and free from dirt. When the boot tears or splits, grease leaks out and contaminants can get in, accelerating wear of the joint’s components. A worn or damaged CV joint often makes a distinctive clicking sound, especially during turns or acceleration, because the degraded ball-and-socket bearings mark their movement with audible clicks. The boot itself is the most common failure point because boots are exposed to road debris and heat and tend to crack or split before the joint fails, leading to grease loss and accelerated wear. So both statements are true: a failed CV joint can produce a clicking sound, and torn or split boots are the most common CV joint failure mode.
