It is necessary to replace the CV joint boot if it's broken. Here are the specific details: Reason: After the CV joint boot is damaged, the grease inside the CV joint will be thrown out, and dust and dirt will enter the CV joint bearing, causing abnormal wear and even leading to the CV joint seizing. Material: The material used is thermoplastic elastomer, also known as thermoplastic rubber, which is a polymer alloy material between rubber and thermoplastic plastics, possessing the dual characteristics of rubber and plastic. Function: The purpose of the CV joint boot is to contain the grease, preventing it from leaking out and ensuring it stays inside the CV joint. Once the grease inside the CV joint is insufficient, it will cause excessive wear and premature damage to the CV joint. Repair requires replacing the CV joint, which is relatively expensive. Therefore, once you notice any damage or oil leakage in the CV joint boot, it must be replaced promptly.
