I have noticed numerous 2007 ford edge owners with the same issue I had recently, leaking transfer case PTU unit. I also noticed this same issue is happening with Lincoln's and Mazda's of same model type. I believe Mazda has offered owners some sort of compensation/recall/extended warranty for this manufactured defect. My question is what is Ford going to do about this very expensive repair that owners have to pay for that is a manufacturer defect? I did have it replaced for a pretty penny and now I hear a clanking noise when I turn that was not there before the repair. Does anyone know of any class actions on this?
