Man, I hate to ask this but have the wheels been swapped side-to-side.
I can't imagine your mech didn't do that first, but you didn't say.
It looks like a bent wheel.
I rotated my wheels last week (I do this every 5k miles). This was well before My mechanic told me I have a bent axle. Rotating wheels didn't change the squeak at all.
