I just listened to my V6 motor with the cover off and hear a "thunk" when the engine turns off and i suspect its the SC coupler. Below is a link to the short video, wait until the very end for the noise. Any comments are appreciated.

Yep, that is the worn isolator "clonk" for sure.
And before that the classic "marbles in a tin can" rattle is obvious.

 

Thanks

Here's a question for the group: Has the solid coupler fallen out of favor due to increased resonance/noise? I would hate to do this elective change-out and make things worse. See at 12:00 mark on this video:

Yeah, it seems that the solid coupler could be noisy based on those videos you linked. I'm planning to use the OEM one since I'm having my JLR dealer do the repairs and they probably would not put in a third party part anyway.

 

When my JLR dealer replaced the coolant pipes in my car (with the metal Euro Amp versions), I had them also replace the water pump and renew the supercharger oil as well as replacing the coupler. I provided an aftermarket coupler but they reported that it did not fit well and made noise immediately. They then installed a new OEM coupler: no noise.
