Greetings and Welcome to Just answer.
TO remove the axles, you first need to remove the rear diff cover. Then remove the bolt and center pin. The bolt is an 8mm bolt. Once you slide that out, with the transmission in neutral, turn the drive shaft so you can get at the opening. Then you push the axle in and use a magnet to get the C clip off the end of the shaft. You may need to roll it around a bit and the brakes and rotors need to be off.
