Hello!
I have a 2001 Mercury Sable. I am having trouble with a strange (whining?) noise. It happens only at low speeds and typically when I am hitting a sharp turn and accelerating. I have uploaded a video on the web. The noise can be heard very clearly at 29 seconds, unfortunately tinypic doesnt have a duration counter but you should be able to hear it. PS sorry for my dogs annoying breathing in the background. 
Thank you!!!

This video was taken with my iPhone, might need to turn volume up.
