I have a 2000 Ford Explorer Sport. I was getting an oil change and they SAID I needed to get new differential fluid, but I don’t know if I should trust this shady place. How often do I need to change the differential fluid, and is there any way to know other than time?

Do I need to replace the Differential Fluid?

Make sure yo have no leaks,if you dont,just check the level it should drip as you loosen the nut if its full.

Check the breather tube
