"..... only does it after car sits for awhile. It's like a squeak and scrub sound, at slower speed, and mostly when deacceleration ..."
My ten pence worth. Nobody seems to have mentioned half shafts. Universal joints? Split boot? Regreasing?
Maybe water has penetrated a split boot. When left bearings dry out. When warms up grease penetrates and squeak goes away. Deceleration takes the load off the joints.
Can you regrease half shaft UJs? Worth a look do you think?
