you'll need some basic tools, sockets will make things go a little faster.. Someone can chime in for the size of the nut on the HUB.. I know it's a large one..
Bring rust buster and a breaker bar, I used the handle off a Hi-Lift and then stood on it and jumped up and down (for the large Nut).. Needle Nose pliers to remove the pin on the tie rod, it will be much easier to get the bolts behind the hub with the tie rod off.. It shouldn't take much time to do this but i know where your comin from doin things in the cold.. I don't have a figure for the mechanic, but it shouldnt take him no more than 2hrs at the longest.. you can get the axle at pepboys for $70 or so + the core charge.. and maybe ask them how much it would be to do it..
