for a 2001? You don't need one. On my 2k, I just unbolted the old hub, bolted the new hub, plugged the vaccum line (so debris wouldn't get into the new hub) and that was it. If you have the older mechanical hubs THEN you need the spindle nut socket. Elsewise, it should be plug and play. For my fiance's 97, I used a screwdriver and a hammer to tighten down the spindle nut.
