How do I check the oil level?

This differential cover includes an oil level sight glass for quick and easy oil inspection. The pre-installed sight glass allows you to visually check the oil level without removing any plugs. This makes maintenance easier and more convenient.

What is the purpose of the calibration plug?

The calibration plug is set to the factory oil level to eliminate overfilling. This helps maintain optimal performance and prevents potential damage from having too much oil in the differential. Refer to the manufacturer's instructions for proper oil level guidelines.

How often should I change the fluid in the differential?

The manufacturer does not specify a fluid change interval. Consult your vehicle's service manual for recommended maintenance schedules, as well as fluid specifications. Regular maintenance helps ensure the longevity and performance of your differential.
