First off you can't put manual hubs on a second gen. They're not really auto either, they're permanently engaged.
You can get a new hub/spindle assembley at Advance Auto for around $200.
Changing them is not hard. Take off the tire, take out the two bolts that hold on the caliper and then the two bolts that hold on the caliper bracket. Take the rotor off, if you've never taken it off it will probably be rusted in place. Once you get the rotor off, take the CV nut off, then the three bolts that hold the spindle on off. Theres a little bolt that holds the ABS wire on. Take that off then follow the wire and unplug it, behind the front bumper.
