How does the sight glass help with maintenance?

The sight glass allows for quick and easy monitoring of the oil level without removing any plugs. This simplifies routine checks and helps prevent overfilling, which can damage seals. The calibration plug is set to the factory fluid level.

What is the purpose of the magnetic plugs?

The magnetic drain and fill plugs attract any ferrous metal particles circulating in the oil. This keeps the oil cleaner, which reduces wear on the gears and bearings inside the differential. Keeping metal out of the oil extends the life of your components.

What kind of maintenance is required for this differential cover?

The differential oil should be changed according to the vehicle manufacturer's recommended service intervals. Check the fluid level periodically through the sight glass. Inspect the magnetic plugs at each oil change and clean off any accumulated metal particles.
