Rent a torque wrench, ball joint press, pitman arm puller, and 36mm axle socket. You have to remove the tire, brake, and wheel hub. Put antisieze on most things to make it come off easier in the future. Usually it's a good idea to replace the spindle nut as well. Most say to do it every time, but at least replace the Cotter pin. A breaker bar is necessary, and an impact gun will save your back.
Torque for the spindle nut on the wheel hub is 175 lb-ft. Get a new universal joint as well. Also consider doing the other side, and replacing each with a chromoly axle shaft.
