if you are talking the axle shafts themselves it is fairly easy and pretty straight forward. There are axle retainer nuts that you will have to remove, should be 4 in total.
Just Rotateaxle to line up hole in axle flange w/one axle retaining bolt.
Remove axle retaining bolt.
Repeat this 3 MORE times to remove a total of 4 bolts.
Remove axel by pulling straight out. It may require substancial force to be removed.
If they are stubborn then you may need a slide hammer for extrication.
Pretty straight forward.
