I'm glad you're getting there. It's only hard the first time, or if you get a bearing that's seized on the spindle. Those kind of suck.
If you're not sure how to inspect the bearings, post some pics of what you find. I wouldn't go through replacing the bearing and driving the race out and all that unless it's bad. If it isn't broke, don't fix it. If the bearing is still good, simply re-packing it is all that's required.
