Which statement about CV joints is true?

Which statement about CV joints is true?

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

Answer: (C)

When a CV joint starts to fail, one classic symptom is a clicking or popping sound, especially noticeable during turns as the joint under load lets the worn bearings click. The boot’s condition is the gatekeeper for the joint’s life: a torn CV boot allows grease to leak out and dirt to get in, which accelerates wear and leads to eventual joint failure. Because each statement describes a real, common failure mode or symptom, they both fit accurately. Together they show two common aspects of CV joints: a failing joint can click, and the boot tearing is the main cul­prit behind many CV joint failures.
