CV Joint Boot
A CV joint boot is a protective covering made of rubber or other flexible material that surrounds the constant velocity (CV) joint on a vehicle's axle. It is designed to keep dirt, debris, and moisture out of the joint while keeping grease inside to lubricate and protect the moving parts. The boot is essential for maintaining the functionality and longevity of the CV joint, which is responsible for transferring power from the transmission to the wheels while allowing for smooth and consistent rotation, even at sharp angles.
