Why does a 1997 Ford Explorer squeak when turning?

Answer 1

We have a 2000 Ford Explorer and have dealt with squeaking also. I have read many questions and seen all the answers, but I solved our problem real easy. It may not be the cause of yours, but check this out. Our squeaking was coming from the "plastic", I'll call it plastic, step cover, or rear bumper cover. There is a molded piece that sits on top of the bumper and gets tucked under the rear quarter panels, kind of like a grip step. I applied WD-40 to the areas where the piece tucks under, as well as all along where it sits atop the bumper. Our squeaking is gone.
