Drivetrain Noise While accelerating and decelerating

[M32H32IS]

Did you figure out what that noise was?

No, but I got a great deal on used driveshafts with only 12k miles so I ordered both front & rear. Once I install them I’ll update the thread.

Check the park brake release cable.
May be rubbing on the drive shaft.

If there are half shafts with CV joints I'd look there, but typically CV joint failure starts with a clack noise while turning. Yours does it going straight and it sounds like the clack noise is coming from the center but it is hard to tell from vid. Its also interesting that speed and/or acceleration seemed to play a factor in that the clack didn't start right off 0 MPH.
