I still have flashbacks to exactly this with mine..

My pop had a stuck wheel nut on his 76, it took a torch, a 3 ft breaker, and a 8 ft cheater to break it off. The powers of nature vs a 200lb gorilla with a wrench.

get a torque dude and never worry about that again :)

Yeah, basically as tight as you can with a breaker bar. Check the warranty on that torque wrench.

I wouldn't have even attempted that, I just bought a 36mm slogger for that job instead after doing research, basically a super heavy duty spanner you twat with a mallet. 

Well..
