My bar still had end caps. The noise was due to the resonant frequency

turns.

I pity the poor guy, driving behind you, if your caps should ever come
off.

I have a bigger worry for you. I didn't bother with tower locks when I got
the racks. Theft isn't very likely in my village & there was no mention of
other reasons for the locks. I drove somewhere & found that a tower was
adrift because the latch holding the tower to track adapter was open. I
thought I had missed latching it until it happened a few more times.

A little sandblasting is nothing compared to hitting a sand filled bar with
canoe attached. I have locks now, just to keep the latches from opening
themselves.
