I have a 2005 Toyota Highlander. When I start it, it makes a noise like an empty drum scraping along the pavement.
The noise only happens when I start it up or when I am slowing down and putting the
brakes on. I had the brakes replaced about a year ago.
Might be one of your exhaust heat shields that has come loose from rusting.
This was my problem and solution today, on my 2006 Highlander, that had been driving in salted area for about 6 years of its 11 year life.. Brake / dust back shields now removed from the rear wheels (one side essentially had fallen off and making noise, the second was about 50% rusted away). All is perfectly quiet now.
