Driveline noise wtf?

[Doubeleive]

any idea's?

called the local driveline shop he said the aluminum gets stressed and will make that noise, not completely sold on that but sounds like the most reasonable explanation.

Never heard anything like it. Crazy, yo! I bet you can hear it clearly in the cab and it drives you nuts!

I’ll be interested to see what it turns out to be.

another video, lot of wind noise but at 1:28-2:10 you can hear it and again at 4:00

That would drive me nuts.

Kinda sounds like a ujoint... but a bad one usually sounds like that crunching / moving by hand, not when installed. I’d probably drop my driveshaft to feel all the joints.

X2.

Hopefully this isn’t as elusive as that annoying body creak I have was.

Is it for sure coming from specifically the driveshaft? You sure it's not just acting as a speaker, resonating something in front of or after it?

The explanation from the driveshaft shop is a thing but I've never heard of that happening on anything but a drag race car and it was because the shaft was piecing apart inside due to being abused relentlessly by a 800 HP car on slicks.

I'd lean more towards U-joints to start and I wouldn't be afraid to pull that driveshaft and check the pinion, maybe even open up the differential to get a look and see if any metal has chipped off.

WTF indeed. I’m curious to see how this thread ends.
