Mike - THis is what happened to me - the person helping me the first time
used an impact wrench to tighten the nut - well it wasn't tight enough.

While we are on this topic - I've also been told you should never tighten
these with the wheel on the ground - well how is it possible to do this
with the wheel in the air - that's enough torque that at some point the
wheel spins. I had to put mine on the ground and block the wheels to get it
to a high enough torque (I'm ready for ya - all - flame suit is on).

I know I could have done this job without the fancy torque wrench but I had
forgotten the math and I needed to see with my own eyes that this was
torqued properly - the issue that started this entire adventure for me was
that the wheel came off at 55+ MPH - and then I nearly had that issue while
traveling after I didn't get ti tight enough the first time.
