If you have all the tools, and take your time it's not bad. You should only have to reset backlash since you are not changing gears, so a mounted dial indicator and basic tools will do the job. It's one of those things; if you are not totally comfortable, or don't have an experienced buddy to help, you might wanna pay the 200 to have it professionally done.
edit: I think that front axle is a "shim" design to set the backlash, not 100% though.
