This is an important step as it take a lot more torque to get a nut that 
has been tiightened in place moving than it takes to keep it moving.  
Thus, loosening and then torquing to spec by having the nut moving as it 
comes up to the required spec is a much more accurate method of gettint 
it at the correct torque.
