[TR] TR3A Nut behind the wheel

[Randall]

I believe you're supposed to peen the nut lightly, to help lock it to the
threads.  This is mentioned in the TR4 manual.
Or a couple drops of purple Loctite should do nicely.

But I've never done either; perhaps because I tighten mine with a socket and
big ratchet.
