High pitch sound from right front end

[H2D2]

I've noticed this problem only when I've been driving for a couple hours. As I accelerate through the power band I hear this very high pitch sound from the right front end.

I ended up getting some front end repairs done cause the arm that goes to the steering column was lose so you could wiggle the entire wheel when it was suspended in the air. I thought that would fix my high pitch noise problem, but it hasn't

Has anyone else had this problem with their rig? It only happens when I've been driving for a while so it is very hard to duplicate; bringing it in to an inexperienced mechanic when it comes to H2s will make this near to impossible to fix.

It's hard to explain the noise, but imagine having two metal cylinders where one fits perfectly inside the other, with just enough room to spin a little. Imagine the noise that would be created by spinning the inside cylinder super fast and that is what I hear when it accelerates after running for a while.

Any guesses?
