Check the archives for stuff on the horn ring on steering wheel. I
can't recall the exact anatomy of the steeering column right not, but
the scraping could be the ring or contact, debris in the way, or could
the wheel be scraping against the black tube? (that part of anatomy I
can't recall right now)
As far as horn sounding, check the wire going through steering column
and spade connector at coupling. (flanges) It could be frayed.
I loosened/tightened the steering wheel nut by placing a piece of 2x4
under arm in steering wheel. The rubber in arm may flex a little, but
it shouldn't hurt it.
