The steering feels loose, I can turn the steering wheel about an inch in each direction before the car starts to turn, I have had the ball joints replaced and I have been told the tie rod ends are good. It is kind of scarey at 70 mph on the freeway. Any suggestions what is causing this.

wheel bearing. Lift the car so the wheel is not supported and twist it up nd down,, then right and left. You will feel the play.

With the information given this is not a sure solution. Questions that need to be asked is when does this happen, turning at slow speedm high speed, when hitting a pot hole etc? Since you have replaced a lot of things already, assuming you have NEW good quality parts so you did not replace bad parts with new bad parts i would definitelu check the pitman arm. This runs from the stering gear to the tierod. It can give you some good clunks while steering, especially at low speed when there is a lot of resistance. Check it by having someone turning the steering wheel when watchin/feeling it.

check the idler arm and pitman arms
a quik and dirty way to check for play in the front end
is to have an assistant rock the steering wheel back and forth while feel an all the joints in the steering gear for play.
there will likely be more than one loose joint.

raise the truck and have some one rock the steering wheel back and forth while you look for excessive movement at the idler arm - also check is the input shaft on the steering gear box rotating more than the output(pitman arm side) i've seen more steering box failure in the last several years especially true with big tires or boggy road driving, a rebuilt box can be bought at a local parts store- o'reillys, advance, napa etc.
