It features Sentinel vent technology that filters out dirt and moisture to keep the wheel-end oil clean, extending bearing and seal life. The cap includes a sight window for checking oil level and condition. It is replaced when the window cracks, the gasket leaks, or the cap is damaged to prevent wheel-end failure.
