A clicking sound during sharp turns on a FWD car is most likely caused by a faulty:

A click when you turn sharply is a classic sign of a worn outer CV joint. In a front‑wheel‑drive setup, the outer CV joint is the one that has to accommodate the most angular movement as the wheel steers. When that joint’s bearings or cage are worn, they lose smooth contact and produce a distinct clicking or popping sound each time the wheel is steered through a turn. The outer joint endures the greatest articulation, so it fails with a noise pattern that appears specifically during sharp turns. Other components don’t fit this symptom as neatly. A steering rack issue can cause play, stiffness, or clunking related to steering effort and position rather than a clean click tied to turning. A wheel bearing typically causes grinding or humming that changes with speed, not a prominent click during turning. The inner CV joint can cause vibration or noise under acceleration, but the sharp-turn clicking points more directly to the outer CV joint.
