A Guru friend of mine inquired about how I was torquing lug nuts, so I'll share with those who are interested. I called Newell & they stated all lug nuts on my coach should be torqued to 450 foot pounds.
Good truck tire shops use a 5' long torque wrench that is hinged and "breaks" when the torque is reached. I feel this is the best. They cost $600+ http://www.alltiresupply.com/p-TM750-1.html
There are also some heavy duty 500 pound torque wrenches. This is just an example: http://www.toolbarn.com/ampro-t39923.html
I have a Snap-On 4X multiplier that I use with a 1/2" drive torque wrench. The multiplier has a 10 to 20% loss, so I use 15% loss. 135 foot lbs on my torque wrench times 4 equals 540 foot pounds times .85 equals 459 foot pounds. The multiplier works best when working on a hard surface floor.
Others may use other tool or alternatives.
