Engine: 2.4 L
See above video link.
I've been having this odd sound occur while I accelerate - sort of like a grinding sound (about 7 seconds into the video). It might be a bit difficult to hear over the other sound coming from my car... It occurs a lot more frequently when it's cold, when I'm accelerating, and when I am turning while I accelerate.
Also, the more obvious noise that occurs throughout the entirety of the video just began today. It does not occur while I'm stopped and it began when I stepped on the brake a little harder than usual...
Any input would be appreciated, because I know nothing about cars.
