Driveline noise wtf?

[swathdiver]

any idea's?

Put the stethoscope on the driveshaft and tail shaft of the trans. I'm thinking u-joint too or a chipped tooth or spline. Shouldn't be anything in the driveshaft tube but that cardboard but what if a booger weld fell off and started bouncing around? The test for that is to put the driveshaft on a driveshaft balancer and spin it up.

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

I’m glad you didn’t drop your phone. Although...it certainly would have given me a chuckle.

I had a rear U-Joint break on me once (on a ‘93 Wrangler) with no signs that it was failing. The driveshaft ended up whipping around beating everything up. It was rather amusing. It was a I-6 and I pulled the muffler and put dual exhaust on, so maybe I simply couldn’t hear that ticking noise that you have.

While I have never heard anything like that before, I'm inclined to think it is universal joint related, rather than driveshaft related.

if this was the case I would think the noise would be centered around a u-joint then but this noise is coming from the shaft, which is why I moved the camera from end to end to see if the noise was more at one end than the other.

thank you for everyone's input, it was the U-joints both ends were fried, replaced and noise is gone.
this was at 160k on a 2005

Glad that you found the source and fixed it. The hollow drive shaft must have worked kind of like a speaker, and projected the noise all along it, thus giving you the noise all along it, when you were checking it out to find the source.
