here is a little better step by step...
1) remove the center pin bolt with a 12point 8mm BOX end
2) tap out the center pin slowly till you can grab it and pull it out of the carrier
3) pull the C clips
4) pull out the axles about 3 inches, you can leave the rims and tires on them.. ive done it too many times
5) remove all the gears, make sure you take the spider shims too, dont leave them in
6) replace and reverse the above for installation
