Just going to change my rear wheel bearings. I am confused on the torque of the large driveshaft hub nut. It says 330N/M.... plus 1/3 turn.? Is this correct as thats around 243 foot pound ...plus 1/3 turn? Seems a hell of a lot.
 
It's a sh*ton, that's why the forum is full of posts about how hard they are to get off. I just tighten them down until I can't, they've stayed on(for now).
 
Assuming all model years are the same (I believe they are), the rear driveshaft nuts on an F2 are 395Nm, or 291 lbf-ft.
And you should use a new nut 😉

You still need a big torque wrench.
 
I do them up to maximum of my ½ torque wrench, which is 230Nm, then switch over to my ¾ breaker bar and trolley jack handle to give them a final tweak.
With torque that high, a few Nm either way is of no concern, providing the threads aren't damaged by over tightening.
