Noise coming from Transmission and rear
 

Hi mates!I am new here. I live in Germany and bought 3 weeks ago my 370Z in pearl whit. So far very happy, but i have noticed these follwing two problems. When i have the neutral gear i hear this noise that you will hear in the following video and also when i brake in low speed i hear a 'clunck' coming from the rear of the car. Sorry for my english. I hope you can help me with your experience. Here is the video:

Normal for the noise in neutral. I would say normal for the "clunk" noise when braking or possibly your rear axles need lubricating, it's kinda hard to pinpoint.
