No.

Not necessarily. You're dealing with a taper fit here. If the nut
loosens up and the end of the tie rod moves up out of the taper, it will
be free to move.

Again, not necessarily.

Maybe. This is a prime example why, in most cases, nylocs should not be
reused. I would most definitely get a new, quality nyloc nut asap!

Again, not necessarily.

The alignment was not done properly? Are the wheels balanced? Do they run
true or within tolerances in all planes (radially and side-to-side)?
Anything else loose anywhere up front?
