I have a strange problem that popped up a week or so ago. Now when my
toilet stops running (after a flush), I hear a water pipe in the
basement shake for a second or two. This does not happen when any sink
is used, or the shower, just the toilet. I figure this is bad for the
pipes (well connections anyway). Any clue what this is? Why does only
the toilet do this?

It is called water hammer, caused by the yoilet fill valve shutting off
too fast. Sioux Chief makes a water hammer arrestor, put it on a tee
you install in the cold water line near the toilet.

Sounds like water hammer. Lots of possible solutions and causes. If
your water pressure has increased, that could be it. Turning down the
shutoff to the toilet so it will fill slower, may help as might better
securing the water line in question or turning off the water supply and
draining your water lines, then turning stuff back on. This sometimes
returns the function to anti-hammer devices. You might also want to install
a anti-water hammer device as suggested by Stretch.
