Must the CV joint boot be replaced if it is broken?

[DiBrandon]

CV joint boot must be replaced if it is broken. After the CV joint boot is damaged, the grease inside the CV joint will be thrown out, and dust and dirt will enter the bearing of the CV joint, causing abnormal wear of the CV joint, and even causing the CV joint to seize. Related introduction of CV joint boot: 1. Material: The material used is thermoplastic elastomer, also known as thermoplastic rubber, which is a polymer alloy material between rubber and thermoplastic plastic, with the dual characteristics of rubber and plastic. 2. Function: The function of the CV joint boot is to wrap the grease, preventing it from flowing outside and keeping it inside the CV joint. Once the grease inside the CV joint is insufficient, it will cause excessive wear of the CV joint and premature damage. Repair requires replacement of the CV joint, which is relatively expensive. Therefore, once the CV joint boot is found to be broken or leaking oil, it must be replaced in time.
