Like my title says I'm having a rattle and creaking sound coming from the right rear of the car. It makes the sound when letting out the clutch and putting it under load. Even when I let off the gas and get back on it it will make the noise. Just not as pronounced. I tried researching it and didn't get any definitive answers. I understand that it could be the diff bushings or some of the other bushings in the rear suspension. I'm trying to not blindly throw parts at the car if at all possible. Suggestions as to what this could be? The car is a 08 G37S coupe with 65k on it.

 

Nobody has any ideas?
