There are still a few possibilities;
Is the tire as old as the noise? It could be the source of the noise.
The alignment could have too much total toe which tend to cause irregular wear and tire noise. I can see this happening especially if it was an insurance comapany paying for the fix.
You can fix it yourself if it is unitized and bolted in. The only thing you might have to do if it is not is take it to a shop and have them press the bearing in and the ball joints. You can borrow these tools from Advance Auto or Auto Zone on a loaner basis.

Also take note if the noise changes with truck or engine speed by putting it into neuatral while moving and letting the RPMS drop.
