I seemed to have developed a "creaking" noise in my steering wheel. Sometimes when I turn the wheel either way I seem to feel and hear a "creaking" noise coming from the column. Is there anything in there that would cause this? Or is it a power steering box problem. I have recently replaced all subframe and control arm bushings too. They look fine. No play at all in the ball joints or steering that I can tell. Any ideas or hints for troubleshooting.
