Protecting the Drive Axle Joint
The Split Rubber CV Boot is installed on the outer CV joint of front-wheel-drive vehicle half-shafts. It protects the grease and precision bearing surfaces inside the CV joint from external contamination. The outer CV joint is the core component that transfers engine power to the drive wheels. It works under combined steering and suspension movement conditions. The operating angles change frequently. Speeds are high. Loads are heavy. Once the Split Rubber CV Boot cracks and grease leaks out, the CV joint wears abnormally and may even break. That can leave the vehicle undrivable. This boot determines the CV joint's "service life" and the driveline's "reliability." In simple terms, it keeps the CV joint from "wearing out" and the drive shaft from "breaking."
