Clicking or popping when turning under load
Clicking or popping sounds while turning and accelerating usually indicate problems with transferring torque to the wheels. Ignoring this sound is extremely dangerous, as the component could fail completely while driving, leading to a loss of control.
Likely causes — most common first
Worn outer CV joint
Clicking is most often caused by metal wear inside the CV joint, which transfers torque from the gearbox to the wheels during turns. Under load, the internal balls begin to slip and strike the housing, creating a distinct clicking sound.
Split or damaged CV joint boot
The rubber protective boot can split due to age or hitting an obstacle, allowing dirt and water inside. This washes out the grease, causing the metal parts to run 'dry' and wear down rapidly.
Worn inner CV joint
The inner joint is located closer to the gearbox and handles the up-and-down movement of the driveshaft as the suspension works. Wear here causes clicking during turns as well as vibration during acceleration.
Loose wheel nut
The central nut securing the driveshaft to the wheel hub can loosen over time due to stress or incorrect tightening. This causes play (wobble), resulting in clicking or popping when changing direction.
