Front wheel squeaks when turning steering wheel

It doesn't seem to have slop in the steering (yet, I guess), is this likely the upper and lower ball joints, tie rod, or something else?

 

It sounds like no more power steering fluid in resovoir. You check fluid?

 

Seems to only squeak on the left side though, like a joint needs grease sound.

 

I know this is old, thats a tie rod end that needs replacing.....

 

There was a bunch of junk in the wheel when we took it off, cleaned it out and squeak stopped This truck lives its life off road, not really surprised.

 

Sound just like a really shot outer tie rod end to me, gnarly squeak when you turn the wheel...
Could have been a lower ball joint too, heard similar noises many times.
