What is the purpose of the calibration plug?

The calibration plug is set to the factory oil level. This helps prevent overfilling the differential when you add new oil. Just fill until oil starts coming out of the calibration plug hole.

What maintenance is required for this differential cover?

The magnetic drain plug should be cleaned at every oil change. This removes any accumulated metallic debris, ensuring it doesn't circulate and cause wear. Refer to the manufacturer's instructions for proper cleaning and maintenance schedules.

Is there an upgraded fill plug available?

Yes, aFe offers an optional deep reach magnetic fill plug (PN: 46-00002). It's sold separately. The deeper reach helps capture more metallic particles.
