Must the CV joint be replaced if it makes abnormal noise?

[HadleyLynn]

CV joint must be replaced if it makes abnormal noise, for the following reasons: 1. If the CV joint makes abnormal noise, it indicates that the CV joint is already damaged and needs to be repaired or replaced. 2. In the early stage of CV joint damage, it usually does not make noise when driving straight but makes noise when turning, which does not affect normal driving. However, if not repaired or replaced in time, the situation will worsen until the CV joint falls off and the vehicle cannot move. Therefore, it should be replaced in time. 3. Reasons for CV joint damage: Generally, the abnormal noise of the CV joint is caused by the loss of lubricating oil inside the CV joint due to the damage of the boot, resulting in increased internal clearance and dry friction, leading to abnormal noise.
