A front-wheel-drive vehicle has a clicking noise in the front of the vehicle when cornering below 20 mph. The front end of the vehicle is lifted and supported on safety stands. With the right front lower control arm lifted with a floor jack, the clicking noise is heard, but with both front wheels dropped downward, the noise disappears. Technician A says the right-front outer drive axle joint is worn. Technician B says a worn inner drive axle joint could cause a vibration during acceleration. Who is correct?

Question

Quizplus · Accepted Answer

The clicking noise when cornering at low speeds is a classic symptom of a worn outer CV (constant velocity) joint, supporting Technician A's diagnosis. Technician B's statement that a worn inner drive axle joint could cause vibration during acceleration is also correct, as inner CV joint wear can lead to imbalance and vibration under load.
