How do you change the differential oil on a 2000 v6 mustang?

To change the differential oil on a 2000 V6 Mustang, first, lift the rear of the vehicle securely and support it on jack stands. Remove the differential cover bolts and carefully pry off the cover to drain the old oil into a suitable container. Clean the mating surfaces, replace the gasket if necessary, and reattach the cover. Finally, fill the differential with new oil through the fill plug until it reaches the proper level, and ensure everything is securely reassembled.
