Well I have 1999 ford expediton 5.4l v-8 4wd. The problem is when you come to a stop and turn hard left or right it does this hard vibration/bind almost and I can't figuer out what it is. Also it vibrates hard when you hit 20 mph untill about 30mph and after that and befor that nothing. Exept now its starting to do it when you take off too and I can't figure it out for the life of me. Please help I'm open for any suggestions thanks a lot!!
