i know i asked this question awhile ago but i deiced to just deal with it, but its getting worse. anyways when i take a right turn there is a knocking noise comming from the left rear of my car. i have figured out that it is eather the Rear shocks mounts or the Rear subframe bushings i am kind of hoping its not the subframe bushings b/c it looks like a hard fix. how can i tell which is making the noise so that i can fix it?
