Gen 1 AWD binding?

I just decided to mod my mint Gen 1 that's been sitting on the shelf. So i picked up the AWD upgrade as well as the clear/CF chassis. Then, when i put it all together, i noticed that whenever i turn to the left while under throttle, i hear this nasty grinding noise. I know it's hard to understand what i'm talking about, so here's a vid:
