It has a clear plastic press‑fit window that lets you check the oil level at a glance. The “without side fill plug” version means there is no opening on the side for filling oil, so it’s used on axles that are filled through the hub or that run grease instead of oil. You replace this cap when the window gets cloudy or cracks, the gasket starts leaking, or the cap is physically damaged.
