a 1/2" solid L bar thing was about $15 at Sears last I looked. You'll only need the 1/2" size, there is a kit with 3 or 4 available with smaller drive sizes for around $40, but you'll never need the smaller sizes...out of 3 or 4 Sears locations within an hour of me, only one had the thing in stock, but its on their website and they can have it in a day if they don't carry it...I'll try to find a link and post it here...
an impact strength hub socket will be another $20 from there (32mm iirc)...and the piece of pipe will run whatever you are lucky enough to find...its WAY cheaper to do it this way than even renting a powerful impact gun, let alone the air source to run it...
that how-to has a great recommendation too for using a jack stand or placing a jack under the bar once you have it lined up and and the socket on...I put mine at perpendicular to the ground; pointing up...and pulled toward the back of the car...the motion will cause the socket to drop towards the ground as it rotates, which will easily start to round off the axle nut and/or the socket if you are using a cheap one...the jackstand is perfect for helping prevent that...because as much of a pain this is with a decent axle nut; i don't want to think about it if you round it off...
I was expecting a massive pop and for me to go flying...I had a huge comforter over that side of the car and literally an air mattress on the garage floor in case of me doing a back flip (had been drinking haha)...and it actually didn't do that...it just loosened like a lug nut...was easily done by hand after that, just never went from locked to free spinning all of a sudden...but remember these things are factory torqued to something like 260lb-ft...and that is not considering any extra effort that will be needed with it becoming seized with rust and corrosion...it is the single most 'tightened' thing on our cars, so take it seriously...I've seen guys use a big breaker bar, put it parallel to the ground, and try to jack it up to break these loose...blasting the bar apart and sending bullets into the side of the car and everything else near by...Same thing when guys try to roll the car and wedge a breaker into the floor to break it loose...There is no reason to be ghetto about it, if you aren't big or heavy enough to do it yourself with a pretty big pipe...just take it to a shop...this is probably one thing that could possibly kill you if you get impatient or don't use the right type of cheater...
as far as pressing the bearing, I never plan on doing that...an OE assembled hub with a pressed and greased bearing is only around $175 shipped from some online parts stores iirc...and usually has new studs installed...i've been lucky with mine so far, but just installed some H&R spacers on the front that i'm sure will shorten their life...
