Default rearend noise

The rear end noiseOkay so I was just driving normally (something I should never do because something always goes wrong). And this noise appeared.I changed out the torque arm for a UMI but it is the same exact noise. Anyone with ideas on how to solve this problem please help.

looks and sounds like the rear most portion of your driveshaft is barely knocking against your exhaust. i'd grab a rag, wrap it around your exhaust pipe close to there, and pull it down a little to get it out of the way while the driveshaft is turning.

Nah it isn't bumping or rubbing the driveshaft. There is about a 1-2in gap between them. Sorry it's just a bad angle with the camera.

Around 1:25 in the video when the drive shaft is slowing down it appears the noise is heard every 2-3 revs of the drive shaft. I would pull the rear cover off the diff and inspect.

It seems to me that's a blunt sound. I suspect that the driveshaft is hitting the torque arm at some point. It looks like in the video that the corner of the shaft could be slightly knocking. I would remove shaft and inspect both the front and rear of driveshaft.

If it is not the shaft, try looking at the pinion yoke. I think it maybe is hitting the torque arm.

nope not hitting the torque arm either I got up underneath there and looked. Now is it normal for the tires to move in neutral like that only asking because I was messing around with the angle and at one point they were not?
