Do precisely what they tell you in Bentley.  Once you've achieved the
correct preload (can shift the washer with your screwdriver tip
without using it as a lever) you peen the nut in place exactly where
it is right there.  You have to use an unused spot to peen, so you
get to use the nut maybe 3-4 times before you need a new one.

That's why it's a peen nut and not a castle nut -- tiny fractions of
a turn matter.
