Squeal from left rear wheel after brake job

I recently changed rear seals, rotor backing plates, rotors, and pads.

On first drive I hear squealing from right rear, particularly when truck is turning right.

Any thoughts?

remove the wheel /tire and look for scraping on backing plate most likely...

why didn't you replace the wheel bearings////?/?
don't make sense to me...

sanding of the rotors ???

Wheel bearings were good. Only 73,000 miles. Scraping was from the tabs on the backing plates which I didn't realize had to be bent.
