Do i need the special seal drivers/cone drivers? Or can I get away doing the bearings with just the nut socket? I see a kit with all the tools for $279, seems kinda steep...

 

Front or rear? Either way, you can do it for a whole lot less than $250.00. Most auto stores have the front socket for twenty bucks. I am gonna assume it is the front. You can do the bearings with just the socket, torque wrench(for reinstall), a brass drift for installing the cones, and a NEW(emphasis on new) tapered punch to remove the cones. If you try and use an old one you may catch a lot of problems trying to get the punch to grab the little lip.
