Rear axle nut is one tuff *****!
That rear axle nut is one tuff mother to remove! You can see how many 1/2'-drive extenders I snapped. Too many rum/cokes last night and a lifetime of Wheaties for breakfast I guess… I bought a 32mm socket and 3/4" ratchet and extender today and it easily came off with me putting my full weight on the cheater pipe. Anyway, for those thinking about doing this, take it from me and start with 3/4" and save on your inventory of 1/2" stuff. Surprisingly, the cheese-head bolts on the other end of the shaft came off pretty easy—although I sprayed them with PBR and let it set over night.
BTW – I don’t have a torque wrench for 250+ pounds. Is it safe to say standing on the pipe (in reverse) is enough torque when tightening it?

Been there and done that and your advice is spot on.

That's what impact wrenches are for. I learned that from removing nuts on a commercial vehicle I own. A ten foot cheater bar would barely do the job. Finally I ended up just buying a cheap impact wrench. Live and learn.
250 ft lbf is quite easy to apply with a wrench. What you saw was probably far higher than that due to it being "seasoned".

If you know your weight and stand on the cheater bar the right distance from the nut then it is easy to generate the correct torque +/-. EG: If you are 125lb and stand 2 ft from the nut centre then you generate 250ft-lbs of torque. Adjust to apply to your situation ;-)

Use an impact gun. I have a 550 ft lbs 1/2" drive gun which works nice.
Sometimes it takes a bit, but they always come off. I also got a 3/4" T bar with the right socket for popping them and the crank bolt off. Havent broken one yet.

You broke a lot of bits before you went to 3/4" drive.
This inexpensive Harbor Freight set has proven to be able to take a beating.

I should have mentioned that I also have an impact wrench and I did try that for a while. I only have a 2hp/4 gal "pancake" compressor--but after about 10 minutes of scrweing around, it wasn't getting me anywhere.
Funny, but after using 3/4" tools, my testosterone level felt higher

Use the car's weight. Fit a wrench on the nut (shortest possible extension), and jack the end of the arm - will loosen off softly. You may need to roll the car or reposition the socket to get leverage again if the first losening doesnt get it loos enough for hand work.
Tighetning is of course a different thing.
