What are the symptoms of a bad inner CV joint?

[Annie]

Here are the symptoms of a bad inner CV joint: 1. After the inner CV joint is damaged, abnormal noises or jerking usually occur when the vehicle accelerates sharply or decelerates on bumpy roads during straight-line driving. The jerking is particularly noticeable during sudden acceleration or deceleration. The vehicle may also pull to one side while driving. In severe cases, power transmission to the wheels may be interrupted. You can inspect the dust cover and lubrication condition of the inner CV joint, as well as check the working clearance of the inner and outer CV joints to determine the issue. Damage to the inner CV joint mainly manifests as ball jamming, which produces a "clicking" sound (but only when changing direction). 2. If the vehicle loses power and cannot move, it may also be due to severe damage to the inner CV joint. Therefore, if the CV joint is damaged, it must be repaired or replaced promptly.
