Slight sound during hard turns after Eibach rear Sway Bar Install

I just installed Eibach adjustable rear sway bars, made sure all bushing were lubed up and torqued all to spec under load.

The only issue I have, is under hard turning, I hear a slight click in the passenger side rear, almost as if something is moving around in my trunk back and forth. Its very faint and only during hard turns...

All other suspension parts are stock.

Any idea what this could be?

Thanks in advance!

U gotta put I forgot what it is but wax or something... For the "creaking noise". I had similar noise when I installed mine (front and rear). Whenever I'd go over a bump or anything, it'll creak... Not sure if it's the same or not

It's fine over regular bumps including speed bumps (haven't tested on big inclines like steep driveways). But it's only reproducible when I forcefully jerk the car left and right...

Not to be insulting, but have you double checked that everything is torqued right?

No insult taken! I actually have! I torqued the brackets to 52lb/ft and the end links to the body to 85lb/ft.

Is there a torque spec for the hex bolts that lock the bushing of the end link that connects to the sway bar? Could it be sliding? My assumption is that it is play in the end link connecting to the body...but it is torqued...so I'm puzzled!

Honestly, i've found in situations like this the best thing to do is remove the part and see if it still does it. If it does, you can try to identify what it actually is, if it doesnt, you know the sway bar is in fact the problem, and typically just removing something and reinstalling it is enough to subdue any squeaks or creaks.

I think I may have figured out the problem:
I had to order a replacement hardware kit for the rear sway bars, and it looks like they sent me the kit as described as "2005 & Up" for rear bar part #: 35101.320R.

Well my rear sway bar was designed for 2011+, it is part #: 35129.320R. So I think the end link's are slightly different. I should have realized when the provided bushings were too small!

Either way, I emailed Eibach, so hopefully they will be able to send me a new hardware kit.

Quick question: When installing the endlinks to the chassis of the car, do the two supplied washers (per endlink) go on the inside of the bracket (sandwiched between the bushing and bracket), or outside touching the bolt and nut?

I found a photo with it installed and with the washer on the outside of the bracket. My kit comes with two washers. I saw a video of the installation in which he mentions that the washers should be on the inside? The problem with that, is that its already a pretty tight fit, so it would be pretty difficult to fit washers in there...but I feel like thats why I might be getting too much play/movement/clunking.
