while not in motion the front end has a loud squeak when i turn the steering whe

this needs to be insp to make sure of issues. poss tie rod ends, pitman arm or ball joints

I agree with greg its probably a seized ball joint

this happened to me.most f-150s,f-250s,f-350s,expeditions,explorers and more have a common problem with this.i had someone at a front end shop check mine and had to replace the upper control arm and the lower ball joints on both sides.if that is your problem,be sure and get the ones that have grease fittings.i worked at an auto parts chain and sold quite a few of these for various ford trucks,explorers,expeditions,navigators and so on.your wheel could fall to one side,so get checked and fixed asap.
