I'll reuse if they're coming off again in a week.  Otherwise, it seems
like a foolish risk.  If you *have* to reuse due to circumstances,
loctite threadlocker will give you peace of mind... if you want it, wild
one!

I believe with the subframe bolts the concern is that the undercarriage and
cavity wax finish gets on the bolts upon removal.  That prevents you from
getting the proper torque reading on your wrench, and can make the bolts
loosen over time.  Also, it may prevent the Loctite from getting a proper grab
on the bolt/nut combo.
