If they're tighter going in than coming out, that generally indicates
a problem.  If the ends are exposed to the weather often the threads
will want chasing with a die or thread-chasing file before
reinstalling.  If  they gradually get tighter and tighter that is the
sort of thing I'd expect.  If they go in easily and suddenly come up
hard against a stop, that suggests looking around for missing pieces.
