I bought a 12V cheap a$$ impact tool for $10 at a garage/rummage
sale.  Brand new/no name unit that runs of your car battery and it
popped the rear pulley nut off an Audi 5 cylinder and they're on
there with a suppozedly 225 ft/lb. of torque.  Don't expect it to
last forever and wouldn"t use it to put lub nuts on however.  My tire
guy has a Milwaukee in which he paid a lot more money for(Li Ion
battery 14v maybe) and he loves it for wheels.
