Front Drive side tire Squeaks

[ajsierra016]

2016 GMC Sierra SLT 4X4 with 63K miles. Brand new transmission at 61k miles. Less than a month later a new high pitch squeak showed up. It started when I am going less than 30 mph and turning the wheel to the right. I have attached a short video of what it sounds like. I can't seem to be recording when it makes the loudest noise. The noise does not occur when going over 30 mph. It only happens when turning right or driving slowly up a steep incline. Seems to be some metal rubbing on each other in some sort of way? Took it to mechanic and he can't find anything, suggested rotors but that was eliminated quickly. See video for the sounds. any tips are greatly appreciated.
