Hello list,

I noticed a strange "scrapping" noise coming from the bottom of my new
2005 Explorer (< 100 miles)

This noise ONLY occured when I started the car (by turning the
ignition), and put it in drive.  The scrapping noise (the volume varied
but not too much) would last < 1 sec., and it happened within 3 - 5
seconds of the car began to move forward (no noise when the
transmission was in reverse).

Once the car was running, the noise would not appear again, evening if
I came to a complete stop (with the engine still running).

The dealership's service advisor didn't listen to what I have to say
the first time and attributed the problem to the service bulletin
(wrong fluid in the transmission), but it noise persisted after the
dealership serviced the car based on the bulletin's recommendation.

I am taking the car back tomorrow, and I'm hoping someone can help
provide clues for my clueless service advisor.
Thank you very much in advice.
