NONE, because there is no such thing as a 2002 Mustang Cobra.
remove rear cover from differential, find 1/4 inch bolt in the third member that holds the 1 inch diameter pin between the axles. Remove the bolt and the pin, push the axle that you want to remove in towards the differential and remove the C-clip that keeps the axle in the differential. Pull the axle, using a bearing puller remove the oil seal and the bearing. Replace the bearing and the oil seal, make sure it is installed in the right direction or it will leak. install the axle, C-clip, pin, bolt, rear cover, and differential oil.

There is a bolt on the bottom of the differential. Remove it and let the oil drain. once drained re-install the bolt. Now put new oil in it. there is a 17mm cap. Remove it and fill it up with 90w oil until it just barley runs out the cap hole. Put the cap back on. Done.
Fill it with 10-80W gear oil until it drips from the fill plug. 2-3 Qt.
