[Fot] AN hardware and halfshafts

I noticed exactly the same thing with my Spit with a welded diff.  I ended
up switching out the nylocks for K-nuts.  They are easier to get a wrench on
and seem to hold tight longer.  About every other weekend, I have to take up
a couple of them but far less than I ever did with the nylocks.  The
driveline bolts don't seem to have near the same problem.

My GT 6, with a welded diff, has the halfshaft u-joints bolted to it
with AN6 hardware.  I was checking out various things under the car
two events ago and noticed that all of the bolts/nyloc nuts were about
1/8-1/4 turn loose.  I tightened them up, but after the next event
they were about one flat loose again.  There's no way to get a torque
wrench at these, given the proximity to the diff and the u joint on
the other end of the bolts, so I just give them a good yank with hand
wrenches.

Question - are these stretching, working loose (with nyloc), or are
the AN washers, which I find to be fairly soft, compressing?  I really
lean on the wrenches, so I am amazed the nuts are loosening.  I know
the welded diff puts a lot of stress on the system, but none of the
hardware on the outer u joints or the drive shaft, all of which have
smaller hardware, is loosening, and the events I'm talking about are
only hillclimbs - not a lot of driving time at all.
