Bob,

Here's how I got to my comfort level with tightening the nut on my CV axle/hub
setup.  I also have a 150 limit on my torque wrench so I tightened the nuts up
to that limit and tried to calibrate my mind and muscle memory so that when I
reached the torque wrench's limit and put a breaker bar on the socket I could
give it a little more twist that I "felt" like was closer to the 220 ft/lbs.
It was maybe half a flat more.  Basically I did it with "feel"....and finding
my center, to do the torque.  It also helps to know that you're going to bend
the lip of the nut onto the flat part of the shaft as a safety for keeping
that nut from moving....I guess that will hold it...something a little more
high tech might have been nice though.   That's how I dealt with not having a
bigger torque wrench.  No problems for the couple thousand miles I've put on
so far.

  Oh math/physics/engineer gurus..........Here's my question....

  Goodparts CVJs specify that the 1-1/4" axle nut be torqued to 220-250 lbs.
  My audible click-type torque wrench maxes out at 150 lbs.

  It's been suggested that 160 lb me standing on the end of an 18" breaker
bar
  would exert about that torque. I like this idea.

  Richard Good told me that setting the wrench at 125 lbs and putting a 24"
  pipe over it would yield about the right force.

  Then I found these two formulas http://tinyurl.com/97faw7 &
  http://tinyurl.com/774vwv which appear to work math-wise but where does the
  extension go? Between the nut and the drive end of the wrench or can you
  just slide a pipe over the wrench handle to extend it?

  I've also heard that most shops would just hit it with their impact wrench
  and call it a day.

  These are CVJs and the 1-1/4" nut is an all steel grade 8 locking nut.

  So....what's the best way to accomplish this....and buying a $200 torque
  wrench is not the answer though I may just rent one if necessary.

  Thanks

  Bob
