Metal-on-metal grinding sound?

I pulled out from my mother's house, and it was a metal-on-metal grinding sound. It was extremely loud and the only time it stopped was when I was turning. I jacked up the front end of my car and put it in drive and one wheel would spin but the other was not until I hit the gas and when I gave it consistent gas you could hear a grind not constant but sporadically. I noticed every time it did my traction control was kicking in on my dash.
