so i could remove the driveshaft on the Datsun. He informed me that it bit the dust. He texted me this
His response was "well it worked. The Hemi put out a lot more torque than I could." The truck was a 07 Ram 1500 with exhaust/intake/tune. Probably pushed 400 HP.

In the rotary community it is a well known fact that the front hub bolt and the flywheel nut are on with A LOT of torque, and locktited from the factory. The front hub bolt doesn't seem that out of the ordinary(either a 17mm or a 19mm if I remember correctly) but takes over 400ft*lb to break loose, I broke the drive out of a 1/2in drive breaker bar trying to get mine loose once. The flywheel nut is a whole different story though, 2 1/8in nut, with less than 1/2in of profile on it. Getting one off on an engine stand is quite the production... usually takes two people on a pipe on the breaker bar and another person hugging the motor standing on the engine stand to keep it from tipping over. Still ends up with about 5 inches of deflection on the 4ft pipe we use.
If you go to the forums(especially the RX7 ones) the common wisdom for the front hub bolt is to put the breaker bar on the bolt, turn the motor so it's against something solid, pull the fuel pump fuse and give it a quick crank.

400 ft-lb?? I though the axle nuts on my Outback were super tight and they were only around 200. That would be a real bitch to break loose!

That's how I loosened the crankshaft pulley nut on my 5th gen autotragic Maxima.

It's shit like this that's the reason I have my massive titanium Ingersoll-Rand 1/2" impact. It's rated at 1000 ft./lbs. It's over a decade old - the current equivalent to it is the IR 2235TiMAX, which is rated to 1350 ft./lbs.

One of my favorite pics, because it's almost exactly what I needed to do to get the wheel nuts off my wife's Escort.
Next time, I take the sharpened cold chisel and 2 lbs maul to the problem.

That sounds like a solid investment, the impact we have sometimes has trouble with anything over 100ft-lb.

It's ridiculous, like to the point you think you're turning it the wrong way. Comes off with quite a bang too. I actually dented my fender the first time bracing myself against it to pull.

For the front hub bolt, or the flywheel nut? What you said makes sense to me (this early at least) for the flywheel nut, but the front hub bolt is leaving me more than a little confused.

Similarly, I've had the joy of ripping the dragging exhaust off a buddy's Grand Cherokee with my XJ.

I've done this on a WRX. It's more common than you'd think.

Yes, the front hub bolt on a rotary holds the entire front stack in place as well as preloading the torrington bearings and making sure that the rotors sit centered in the housings to make sure the stationary gears mesh correctly, so it's really fucking on there.

So...I read hub, and definitely was thinking wheel hub. Like I said...it was early.
