I'm so lost
Did they replace the belt or use the same one?

Give it some good boost runs and I bet it starts up again. Mine was screaming at me but would quiet down every now and then but not for long.

Dealer called today and they ordered the SC...

Had this problem and I pulled the pulley inspected it. It seemed a little stuck so I worked it lose and put back on. I also cleaned the bottom of the belt and my screaming whine has been gone since. I do have a Metco replacement but will wait another 500 miles to see it comes back. By the way I used a stethoscope to isolate but still took time to find it because it's that loud.

So would this be the Isolator problem?

All these SC problems are starting to run together.

..and when the car goes out of warranty, the S/C will make noise again with the stock unit....the gall on the shaft with the coupler wear is designed to be that way. Eaton engineering. It's baked in the cake, and it won't fail, it just sounds like marbles in a can. You can replace all the factory S/C's you want under warranty, fact is the noise will always be there after time.

This has nothing to do with the isolator which is a rattle, this is a constant whine that increases with throttle but can no longer be heard above 3000 because of the engine noise. My isolator as described stopped making noise around 2000 miles as it probably has grooved the shaft.

I want to believe this is true. But I would also like to see an article or something from Eaton about this situation. Just for peace of mind.

..Eaton won't tell you that, but many guys here have posted that fact enough that it would convince a jury if this was a trial, just sayin.....

Just to be clear, (marbles in a can) is the isolator rattle and you are correct... I've never been worried about that since a smaller pulley has always been in the plan. The problem I have is definitely a failure. It's extremely loud.

Thanks for confirming. Exactly what I have which is bearing and full SC replacement.

...did you have the unit repaired yet? Anything that becomes a howl, grind, whine, or constant noise of one type or another that progressively gets louder over time and useage is going to grenade and fail. Intermittent noise that is a nusaince is different.

Car is at dealer and SC is on order. Mine was squealing pretty bad.

I had just gone though 3/4 tank of hard back roads driving with some other cars. Didn't notice it until I pulled into the garage, but it definitely wasn't going away.

I hope you are back and up and running in short order. I've been lucky so far with mine. Just the usual infrequent noises here and there that we have seen reported. Nothing that raises any concern. The good thing is that Chevy will take care of it no doubt!

Started a list of all of these here

there is a huge write up over on the CTSV forums you can search out. I can't remeber if was a GM or eaton engineer posting in the thread. the wear in the shaft is by design. they consider it accpeptable it never eats into the shaft far enough to mechanically make it fail.

people call it an eaton thing but if my memory is correct it is a GM/eaton thing. the ford unit's use a coupler not issolator on some models. Hence the aftermaket going to a coupler on this blower as well. these shops did not just pull that out of their .... well you knows.

This blower is custom made for GM by eaton.

I read up about this stuff before I even had a car. LSA has been out since 2009. this is nothing new people just did not reasearch the engine before they bought the car. I was trying to figure out the best mods for the engine and stumbled into that stuff. there was no info on this site yet.

my rattle is livable right now and my bearing is quiet but I knew full well these would be issue I may have to deal with at some point before I had a car in my driveway.

to my knowlege there has been nothing done because GM and eaton have not acknowleged any issue publicly that I have seen.

the issolator rattle that some people don't like is by design and will not change. now why the bearings on some are running dry could be a manufactuing or QC issue so who knows how that will all play out.

I have not heard one comment about a revision to the assembly in any way though. Maybe someone who is getting the swap will know if the assembly has been revised in any way.

My ZL1 has 4432 miles and now it is making a rattling noise from the supercharger. Is this something a performance shop could fix???? Sounds like having the dealer replacing the supercharger will only be a temporarily fix.

GM has a updated SC that can replace yours and it has a solid isolator in it, getting them to do it is another thing.

having the dealer replace it retains the warranty and would cost nothing.

having a speed shop fix it would void the warranty and you would have to foot the bill.

It will be up to the dealer to decide if the rattle exceeds the permissible level and falls under the warranty.

From what we understand, it seems that somewhere, perhaps for the 2014 MY, the SC was changed, and now uses a solid coupler now rather than the spring loaded one. If that's true, then the replacement SC the dealer would install would have the same fix that a speed shop would have done. replace the spring-loaded coupler with a solid one.

the entire SC is a single replaceable unit so the dealer would be replacing the entire unit, not just the coupler for a solid one.

Let the dealer fix it under warranty.

some bitches whine all the time, they start off slow, then when they want something, they begin to whine. Yours obviously wants something, are you feeding it premium?

the rattling noise and the squeal are two totally diff things... you guys need to realize there IS NOTHING THE COUPLER CAN DO THAT WILL CAUSE A SQUEAL. it could fall into pieces and t would not squeal. it simply connects to shafts together... that's it.. if the car is squealing it IS NOT THE COUPLER...

Supercharger rattle

I took my car to the dealer and I was told that the rattle was normal. Not only that...that there wasn't a check engine light on so there wasn't a problem. I just had a performance shop check the isolator coupler and the coupler was broken. Had them replace with a solid isolator and no more rattle.
