Here is the directions. As long as you go easy and put a towl or something over the boots you will do okay - you just have to be careful. Also my suggestion is your wire the axle behind the hub to the transmission side of the shaft. I have had the axle expand - at number 20 in your figure and you can't get it back together without either removing that boot or replacing the axle.
You may need a puller to pull the hub off depending on how it is stuck on the shaft. AutoZone does a tool loan program.
