Rick,

Is the scraping sound coming from the column or the steering rack itself? You
mentioned that you had the fluid replaced. That's what is confusing me. Most
power steering systems will have a hiss at the end of each turn when you turn
the wheel at it's limits (lock-to-lock). If you are talking about the
scraping in the steering wheel itself, it's probably the horn contacts. Two
out of four of my Vanagons do that. I bent the brass horn contact and got rid
of the noise.
