Awesome. I just had a 70k scheduled maintenance at land Rover because of the rattle. They said it was normal. They said they "checked my timing chain" other than putting a tension guage on it thru the oil filler cap I don't know how they can. But said my chain is tight as it can be. I'm replacing that coupler myself. My stethoscope hears a knock ! Great video. It all makes sense now. Cheers

Very helpful. Thank you. Will be tackling this one rainy weekend. 😊

Great video, can you do a video of the engine running with the knock?

Same problem with my 2014 Jaguar XJR

Do you have a reference for replacing the part? Don't wanna get the same problem after replacing it. Many Thanks 👌👌

Great! Any clue where I can get the part for a 2016 RR SC?

Thank u for your information. I have a question What if we don’t fix it , does it will cause the problem to the whole engine ? Thank u for your answer

Where do I get the part for a 2013 RRS SC 5.0 I need the part number or name or something!!

It's hard to believe that the guy who designed this part didn't think that plastic may not be the best choice of material for this particular job! $800 + labour? Wow!! Thanks from the UK...we can have a beer at a outside a pub now!

That's awesome! So can we but unsure if we should or not.... And there was a service bulletin to send the snouts back in to land rover so they could engineer a fix, unsure if that fix ever came about or not.. have a beer for me man!

David G due to harmonics and cost plastic is probably one of the best materials.

I changed mine to a solid coupler and it was noisier and ruined my bearings. Was squealing like a stuck hog after a few thousand miles.

Will it put the car in limp mode in anyway?

Very informative video, I was doing the same to my 3.0 lr4 when I tore the snout down I noticed the spring from the coupler was digging into the shaft and left some marks, I'm replacing the bearings as well, do you think it's necessary to replace the shaft or just do the coupler ?

If it’s just scratches you’ll be fine, if it’s gouges the. I’d replace it.

It is NOT always that coupler making the noise. Both mine and a friends make the same marble knocking noise from back half of supercharger at idle. I found a failed coupler but after replacing, still makes exact same noise. His does too and coupler also replaced. Mine sounds like it’s coming from the right side front screw bearing. Bearing failure is also common on these superchargers, especially if they have ran for a while with failed coupler. Oil changes are necessary, too, as the Eaton superchargers have a separate “lifetime” oil in the unit that should be changed regularly too. Supposedly pump cavitation can cause this exact noise also, but I haven’t investigated this claim yet, just sounds like a plausible idea. Dealer considers this noise “normal” after coupler update has been completed.

I've got a similar situation going on after replacing the coupler in mine. How did you troubleshoot the noise down to the screw bearings?

Mine is doing it too, is it safe to drive?

are there any major concerns if not replaced in time? performance issues?

The coupler falls apart and you basically lose boost because the two drives are no longer connected.

About to replace with the green poly version on my car, do you replace or re use the inlet manifold gaskets? Thanks

Use a stethoscope to listen, if the noise is loudest at the snout of the supercharger, there's your problem

Does this get misdiagnosed as a bad motor?

Ok did the job. My pulley would rotate halfway around before catching and turning the veins. After I got in there I see one of the veins had just started to touch the side and make marks. This was due to bad needle bearings from shavings from the coupler. Started cracking bolts when check engine light came on.

Wow $800!

Thanks for posting this. Could this be the same problem as this video? kzread.info/dash/bejne/g4582tucoJvbk5M.html I was told it could be the timing chain but your video makes more sense of the in consistent rattle sound.
