Default Horrific noise when accelerating hard

can't figure it out, might be the torque tube, or maybe pilot bearing. Its driving me nuts. Started out of nowhere and the shifter vibrates. Please let me know what you think it might be. I checked exhaust and it isn't that.

The noise can clearly be heard starting at 54 seconds into the video

Does that sound like torque tube bearings or couplers?

I can barely hear it but the symptoms sound like it could be a failure inside the torque tube. If it happens in any gear then its probably in the TT. I would plan to overhaul it sooner rather than later. RPM sells a kit with new couplers and bearings for a reasonable price. While you're in there throw a clutch, GM throwout bearing/slave cylinder and a new pilot bearing at it. You'll need a very high quality USA made torx bit for the driveshaft coupler bolts and a pair of giant snap ring pliers.

Good adVice, already on it. Bought a new clutch, slave, pilot, rpm couplers, and a new forged 6.0 I'm throwing in it. Btw I should have posted time in video , the noise starts at 54 seconds into the video and its clear as day. Its clanking. Thank you

Can anyone relate to the sound I'm hearing at 54 seconds into the video I posted? I have stuff ordered ready to fix but I'm not trying to be surprised if its something else. I'm gonna replace my pilot bearing, clutch, and torque tube bearinfs and couplers. Please take a listen and give me an idea of what you think it might be. I'm at a witts end and tired if scouring the forums for something similar. It starts at 54 seconds into the video. Thanks

Sounds like the forward Torque Tube Coupler is done and the tink tink noise is the Coupler bolts hitting the drive shaft during power/torque changes when you reduce power…I would not beat on the car anymore until you get the drive shaft removed for inspection as the Coupler bolts could be damaging the main drive shaft tabs/ears…
