How often should differential fluid be changed?
every 30k to 60k miles driven

Can I change my differential fluid myself?

However, the process can differ between vehicles since some differentials only have two plugs — one for filling the fluid and another for draining it – while other vehicles require you to remove the housing cover.
When should you change rear differential fluid?

What is a differential oil change?
The differential is just like any other mechanism with moving parts. It generates heat and friction while in operation. Just like an engine, regular oil changes help to keep parts such as gears well lubricated and clean. Over time, the differential wears just like any other component.
How do you drain the oil from the rear diff?
These are the drain and filler plugs for the oil. Put a suitable drain tray under the plugs and first open the top plug to relieve any possible vacuum inside the diff and help the oil drain out. Now loosen the lower plug and thread it out by hand.
How do I check the oil in my car’s differential?

What is the difference between a differential and an engine?
