The Axle Boot is a vital component of a vehicle’s drivetrain system. It protects the constant velocity (CV) joints by sealing in grease and keeping out dirt and moisture, which helps prevent joint wear and failure. Located at both ends of the drive axle, the boot allows the CV joints to flex and rotate smoothly as the wheels move. By maintaining proper lubrication and shielding the joints from contaminants, the axle boot ensures stable power transmission and reliable vehicle performance during acceleration, turning, and driving on uneven roads.
