I am posting this because there is really no posts about the clunking noise problem I had with my 2013 Explorer. it was very frustrating because I first starting hearing a slight noise when my truck warranty was just about to expire at 35,500 miles. I brought it to the dealer and of course everything was fine, now that it has 41,000 miles the clunking noise got extremely bad and of course, no warranty. luckily it was just the passenger side front sway bar link. The part was very inexpensive at $45 and very easy to change. The noise sounds like a clunk every time you go over light bumps. on the highway, no noise. if you want to save $ just change it yourself. took me about 30 minutes, start to finish. I am sure there will be a ton of people having this issue.
