It keeps lubricating oil inside and prevents dirt, water, and road debris from entering and damaging the wheel bearings. Regular replacement is necessary when the cap is damaged, the gasket fails, or the window becomes opaque, compromising the seal and oil containment. A properly functioning hub cap is essential for extending the life of your wheel bearings and ensuring safe operation.
