How Long Does a CV Boot Last?

[CarsonLynn]

A CV boot can last for over 200,000 kilometers of driving. The CV boot is a protective cover for the car's constant velocity joint. When the inner CV joint is damaged, it produces a metallic sound, and if there is black grease leaking from the dust cover, it needs to be replaced. Damage to the CV boot allows dust to enter the joint, accelerating wear on the constant velocity joint. The constant velocity joint can move in various angles and requires lubrication to function properly; otherwise, it will wear out. The lubricant used in the joint is grease, which is maintenance-free and does not need replacement. The role of the CV boot is to contain this grease, preventing it from leaking out and ensuring it stays inside the joint. The CV boot is made of rubber. If it is damaged by external force or natural aging, the internal grease will leak as the joint rotates. Insufficient grease inside the joint will lead to excessive wear and damage. If the CV boot has reached its service life and the driver fails to replace it during maintenance, there is a transition period for the consumer to replace the part. However, if it is not replaced within this period, the joint may lose its functionality, causing damage to other parts of the car.
