forget the exact sizes, but they are metric. just buy a set of line wrenches. disconnect those first. you will need an extension to get to the head of hte bolt behind the rack. i for get the exact size, but i think its 18mm maybe. you will definately need an 18mm for the outer tir rod-spindle bolts. i think you need a 22mm for the outer tie rod adjusters. bascially install is the reverse of taking out, just make sure to disable the fuel system and crank it over a few times after you added the proper P/S fluid (ATF in our cars). you want to avoid running the motor without fluid as much as possible as this can damage the pump.
