Just thought I would throw this in since the discussion is about torque.
And since our vans have an onerous nut on the rear axle that is problematic
to us at times.

When I was working in the aviation industry, oft times a propeller would
have to be replaced on an engine shaft. The nut holding that propeller on
was substantial and required considerable torque, as much as 2500 lbs/ft. A
torque multiplier was used that had a chain drive that operated through a
series of gears to achieve the desired torque. The thing was called a
Sweeny Wrench. Sweeny Wrenches are still used today and come in different
sizes and configurations. And they are used in the aerospace industry as
well as other industries, where they often must deliver torque values in
excess of 7000 lbs/ft. They are pricey, costing $7000 to $10,000,  perhaps
more. But wouldn't one of the smaller Sweeny wrenches be great for removing
and installing that rear axle nut on the vans?
