Poodles said:put it in third, yank the e-brake as hard as you can, and have someone literally stand ont he brakes and then torque...
make sure everything is out of the way and go from fender to fender as you'll take up the slack in the drivetrain and then you start actually torquing it down...
never had an issue doing it that way tightening/loosening (use different gears if you have to, you'll find one that works)
Might try that out...
I sinched up a pulley to my sway bar, and used that to hold the crank pulley in place to break it off... Worked pretty well, another option.
