Default Screeching / squealing front driver side on braking and acceleration to 50/60 mph

Are these the brakes or wheel bearings? When I am crusing at 60mph+ there's no squealing, barely any if I accelerate. It happens when I start to brake and come to a stop. Then I accelerate to 50mph and it'll be there but then disappear.

Definitely coming from the brakes. You'll need pads at least.

Sounds like the squealer indicators on your pads are starting to make contact with the rotors.

Any reason the noise is still there when I am accelerating? Makes sense if it was just on braking. It is more apparent on braking though.

The noise can occur when accelerating and turning also.
While technically the rotor only spins in the direction the vehicle is going, under load it will flex ever so slightly, hence why you will hear it on turns and accelerating.

Just to go further on my post, I replaced my brakes at 34K miles with aftermarket eBay drilled / slotted rotors / carbon brake pads. They only lasted 12K miles so I don't recommend them at all. When I brake from higher speeds 60-70mph+ to a stop, my brake pedal vibrates. eBay brake pads / rotors are a NO GO. I am currently at 48K miles.

if I can find a link, I'll post.

Sounds like the rotors are warped too...so pads and rotors it is.
