squeak only when wheels are turned left.

Then your problem can only lie in the pads dragging because of a hanging caliper. Spray a good amount of brake cleaner on the slider pins as you work the caliper back and fourth (not much movement). If you really want to get dirty, lube the pins with the caliper off. I have had hanging calipers on half my freakin cars. That lubrication of the pins is just maintenence. For sure!
 
i woulda replaced wheels bearings while the hub was a part... my education was to never reuse bearings that have been in for a while, but thats just me

yea probably just plain old brake noise dude, they sell some stuff at the parts store to get rid of it
