How do I check the oil level?

This differential cover includes an oil level sight glass, so you can easily check the fluid level without removing the cover. The sight glass is located on the side of the cover, making it easy to view the fluid level at a glance.

What is the purpose of the magnetic drain plug?

The magnetic drain plug is designed to capture any loose metallic particles that may be circulating in the differential oil. This helps to keep the oil clean and prevent wear on the gears and bearings inside the differential.

What is the 1/8" NPT calibration plug for?

The 1/8" NPT calibration plug is set to the factory fluid level. This eliminates accidental overfilling, which can cause leaks and damage to the differential.
