Hi
Jack,
Its caused by all
the vibrations that a rolling tire encounters. Its happening on that one
wheel because the gripper teeth on the hubcap that keep it to the wheel are not
applying enough pressure (that cap goes on very easily, right?). This may
vary somewhat by design, but take a suitable pair of pliers and go around the
cap bending the teeth out toward the wheel. Reinstall. If it still
happens, do it again with more bend. If STILL happens, then the teeth may
be fatigued from years of on/ off.
Then (or first)
the answer is to take that wheel and have an all metal valve stem
installed. I did this on my Studebaker Avanti.
Occasionally, a
problem cap will stay in place when put on another wheel. That didn't work
on my Avanti.
Also
occasionally, someone in the past swapped in a non-matching wheel to the rest of
the set from earlier years where the rim of the wheel was formed differently and
simply does not accept a full hubcap.
Let me know what
works. Good luck.

To All,
I have a question about full
hub caps. Not Forward Look cars, but related because of hubcaps. I
put a set of 50's Mercury full size caps on my Chevy van (It was the only set
I found I had and didn't want to reuse the small ones that came with the old
van-1985 van) and one is rotating on the rim. I found it 2 times now up
against the valve stem. What caused this and how do I correct it?
Thanks in advance.
