What sort of torque did you need to remove the hub bolt?

Enough to start bending a 3-foot breaker bar. That's my tightening torque for them as well

Let's put some numbers on this...

40kg force on the bar, which is 392 Newtons, on a 0.914m bar equates to 358 Nm

I think it was probably more than that I can usually put all my weight(70kg+) at the end of 1m bar and it does not budge but with some rocking it does move. I have also had a case when I was younger and lighter that it would not loosen up even with all my weight rocking at the end of extension pipe over breaker bar. Eventually got it loose by resting the bar on ground and driving the car so that wheel turns and lifts car off the ground, have also broken couple of cheaper braker bars.

I had to do that ^ with a Beetle rear hub nut once. Three people hanging on an 8-foot scaffolding tube with a 1" drive breaker bar didn't budge it.

I have enough pie in me to break Audi hub bolts loose without any trouble though

Sorry to go off topic... Reason I ask is I'm thinking of replacing my impact wrench which is 500Nm for the cordless DeWalt, rated at 950Nm. Although a good breaker bar is cheaper.

I have one of these but have not yet used it on a hub. Easily removed wheel bolts though and is very handy for caliper carriers etc

I have a Mac air impact and that just tickles hub bolts. I'd be impressed if a cordless could break them loose. It does help that they're bolts, and they pick up CV grease from the inside of the joint, compared to old VW hub nuts which sit outside and get rusty, but even so, they take a lot of effort.
