1999 Ford Taurus Wagon SE 114k. Went to the grocery store and whenever I turned regardless of speed there would be a loud pop, which I would feel as well. It does not pop the whole time I turn. Sometimes it would pop when I would slow down, or go over a bump. It sometimes feels like its coming from just by the drivers side foot, and other it feels like it is from the rear. It just happened today so I'm not sure why. I do know that when I put any weight in the rear of my wagon, it really sinks down. Could it be a strut problem? If its another problem does anyone have links to fix it? One side note is within the last 500 miles that I have driven it, the only thing that is different today is that is it raining, hard. Finally, how big of a problem could it potentially be worst case? Thank you!
