It is hard to tell from the pic, other than the rust and what looks like a torn grease boot. Is there any play in it, or with the wheels on and the front off the ground can you move the tires in and out w/o moving the idler arm or the rest of the steering linkage, except for the pitman?

More than tread lightly. Leave it like you were never there, nor anyone else.
