Question " Metallic " noise coming from the rear of the car, rear axle failure?(video)

Hello fellas;

I've recently had an annoying/strange noise coming from the rear underneath of the car, the noise just shows up when:

1) Usually moving less than 10mph, mostly in forward more then reverse
2) Usually when it has been sitting in below 30degree temps for a while, or in the garage all night when it's that cold outside (but not in the garage).
3) Usually after it's been sitting off for a while
4) Doesn't do it EVERY time under each of the above conditions, pretty random
5) Stops doing it once the car is moving over 10mph

today I had the car REAR jacked up on a hydraulic stand jacks for inspection, everything looked fine, unless there's a strange voice coming from the rear axle, not sure if its normal, the sound comes whenever I move the wheel forward and backward, please check the video

20 seconds video:




Thanks

Damn...shooting in the dark but check the differential bolts. There is a good amount of reports of broken/loose diff bolts.

Doubt that is your rear differential bolt as that sound has a more pronounced deeper thud rather than being a hollow metallic sound.

The car does have a little bit of sound when you do what you are doing to the car as the differential will turn and it will then move the propellor shaft which also makes noise inherently.

If it's not that, then it could be your brakes (possible but not likely), your axle or something more serious such as the diff or transmission.

Something like this is not hard to trace.
