This 2001 Toyota Avalon is a very quiet car, so you hear everything! I had a clunking sound that was heard on back roads and I show you how I fixed it. I previously jacked up each wheel and shook them but nothing seemed loose. I also thought the spare tire and/or jack could be making the sound because those were a little loose, but tightening them did not help. I then learned that sway bar bushings could cause this noise, so I gave that a try and found success!

You'll see me using my new favorite impact wrench, available here in my Amazon affiliate link:
