Grinding noise when making turns
Anybody have this experience? It only happens when I turn the wheel all the way left. It does not happen when I make slight left turns. The sound is a grinding sound that sounds like metal to metal. The car is 07 gs350 awd stocked other than 19" mrr wheels.
I see older threads of failed ball bearings or rims hitting dust shield, but no definite answers. Any help is appreciated.

I'm not sure how anybody is going to give you a definite answer if you are listing the same symptoms as those of us who have made other threads about this already (and which you have already found).

Just got back from a tire shop to take the snow tires off and asked them to look at it. They say it's has nothing to do with the brakes, shields, tires, rims, etc. They actually told me it's from the first gear differential box. Does this even make sense? I don't know too much about these things so not sure if this is true, but will making a trip to the dealer asap. Last time I asked them to check, paid $90 for them to look at brakes and stuff and they come up with, "we don't know"and charged me the money anyway. Picked up the car after service closed so no one to complain to.

It happens to my 2010 gs350 awd too! It happens only when I make sharp turns slowly (like in parking garage etc ). Happens during left and right turns. Could it be related to the AWD system?

there are lots of possibilities, I would suspect it might be CV joints. but the thing is from what i know CV Joint problem comes with a ticking sound and it happens even when turning wheels while standstill.
usually, ball bearing noise happens only while driving and disappears when you steer to one of the sides (depending on which side is bad).

Typically, grinding when in a turn is either worn/dry cv joint in the axle shafts (more likely to clunk.. but could grind)... or worn/dry bearing in the hub assembly.
Unless the front diff is fried... it wont make a grinding noise. If it makes a grinding noise, it'll do it all the time... not just when turning.
I would get the car on jack stands... put it in neutral and spin each tire by hand. Check for play in the wheel bearings as well.

The diff is one with the transmission they share the same fluid. If your front diff went out most likely the transmission will go out at the same time. So I would write off the diff concern.
A cv axle most likely will make a clacking sound when the go out.
A hub bearing could make that sound, and so can the brake dust shield. What you can do is drive straight and turn the wheel if you can hear the grinding gently press on the brakes, if the sound goes away then more likely dust shield. If the sound is still there but changes its pitch then that could be the wheel bearing.
Our (on AWD) dust shields if I remember correctly appears to have plenty clearance from the disc, but inside theres a little lip and on my car is where I found it to rub against the disc. Its very simple, remove the wheel and on the underside of the brake disc wedge a flat head screwdriver in between the disc and the dust shield, space it out just a little bit and see if the noise will go away.

I was curious if you were able to diagnose the sound/issue with the vehicle. Any info would be great! Thanks for your time!
