Wheel bearings

Has anyone changed out the front wheel bearings? I found the part on the NAPA website, looks like the bearing is serviceable as opposed to replacing the entire hub. There is some kind of locking component on the hub nut and I'm not sure how to remove it or pry it open. I'm wondering if that's all there is to it...remove the hub nut, remove the hub, pop out the bearing and viola. Also, has anyone seen a Haynes manual for these cars yet?
Thanks, Bill

you know i have looked as well for a haynes manual for the aveo and no success. kind of annoyin because for us do it yourselfers if you wanna work on your car and you need a reference theres nothin. i guess people dont take these cars seriously. :disappoin
