While on a lift the car was put into gear. The grinding noise can only be heard inside the vehicle but not while standing outside it and only happens when car is in drive. Help!
Is it more like a vibration and humming, than grinding noise? If so it would be a bad engine or transmission mount. To check bearings while driving.. Find an empty parking lot, Make right and left turns/circles. Making a left, if the noise get loader, the right side bearing is bad. and vice versa. Do around 10 MPH while turning circles.
Testimonial: "No humming or vibration unless I'm on the highway. The noises doesn't change whether I turn left or right. When it was on the lift they did hold each tire to see if the noise changed. noise went away when thee drivers side wheel was held and got louder when the passenger side wheel was held."

So you have two possibilities. The wheel bearing or the CV axle on the drivers side. If it were the transmission the noise would be there no matter what. Do what I said. Take it to a parking lot and pay attention to the noise. Turn circles in the lot. Get up to 10 to 15 MPH and listen. Doing a left turn will put pressure on the drivers side tire. If it is a bearing the noise will diminish or go away making a right hand circle. If the noise stays constant both ways, it is the CV axle. An axle and bearing will have the sane noise up to a certain point. When they get real bad, the bearing will continue the grinding, just worse. The axle will start making a clunking noise.
I did the circle thing. The grinding noise didn't change. The clunking noise started today. What should I look for under the car to verify it being the CV?
Excessive play in the axles. Lift the front and grab the center. They will move a bit new in and out. But not up and down. Also broken boots and slinging grease are good indicators.
That would be"center of the axle"
