You will need the hub tool to remove the nut holding the rotor onto the spindle. You will also need it for re-assembly, as well as a scale to determine pre-load on the nut so that you don't crank the nut down too much and bind the rotor up which would result in HORRIBLE gas milage.

The bearings literally just drop into the rotor. No pressing necessary. There is a seal that goes in behind the bearing at the back of the rotor, but the front one is held in when you sandwich the whole assembly back together.

I would strongly suggest reading this: http://www.vehicross.info/forums/sho...bearing+repack It gives a step by step how-to on replacing the front rotors and repacking the bearings. There is a link in that thread to a how-to over on "The Planet" and that write up lists the tools and expendables that you will need to do the job right.
