On all-wheel-drive equipped vehicles, a popping noise from the front end during turns is usually caused by a/an

• A. Outer CV joint
• B. Front differential
• C. Inner CV joint
• D. Wheel bearing

Answer: (A)

Popping sounds during turns on AWD vehicles usually come from the outer CV joint because that joint has to flex the most as the wheel turns. The outer CV joint transmits power while the wheel steers, so when it’s worn or its boot is torn and grease has leaked out, the bearing surfaces can slip or click as it fully articulates at large steering angles. This makes a distinct popping noise when you turn. Other components don’t fit this symptom as cleanly. The front differential tends to produce gear whine or clunking under load rather than a sharp pop specifically tied to steering angle. The inner CV joint mainly causes vibrations during acceleration rather than a turn-specific popping. A worn wheel bearing usually creates a grinding or humming noise that changes with speed, not a discrete pop during steering. If you hear this pop, check the outer CV joint boot for damage and look for signs of grease leakage or excessive play in the joint.
