clunking noise in rear when turning R orL but not when straight ahead driving.

Open up area where the spear tire is. Chances are that something cell in there or spare tire and jack loose.

If its like mine the whole rear fender well is rusted out. I found my shock floppin around loose cutting out a large whole leading into the rear hatch area...absolutly nothing left to attach new shock to....there's recall for front sub-frame corrosion problems. But ford can't realize they used the same shit material in the back??
