Suspension squeaking in cold temps expected? Looking for some expert takes.

[Rta95]

Car has eibach euro springs, versus camber plates, and eibach sway bars - front and rear. I noticed last fall/winter the suspension would squeak/creak pretty audibly over speed bumps and uneven road surfaces at slower speeds. Higher speeds I couldn't hear anything. Car drives perfectly fine. These sounds started after I put in my eibach sway bars. Sound went away once temps started going up again. This fall/winter, the sounds came back. Not any louder than last year though.

The reason I bring weather up is I didn't think this was weather/temp related till a shop told that might be it. I had three shops look at it (I had to come in for other things and asked them to look at it). Both said things look and feel perfectly fine. Did road tests too. Maybe I'm just slightly skeptical of how thoroughly they looked and trying to think out loud/convince myself things are fine.

So long question short, is this accurate? Would noises like this be expected after the mods I added and the temperature drops? Anything I CAN do to address the squeaking? Should I look at bushings? Replace endlinks? Still have stock ones on.

Poly bushings creak in the cold until they’ve flexed several times.

Were the sway bar and links torqued down when the vehicle was on the ground or when it was lifted off the floor?

When it was on the ground

Got it. Do you know when these bushings get worn out or should be replaced? I track the car a fair amount and am wondering if that accelerated any wear to them.

Short clip but this squeak you can kinda hear is what I'm getting often. Any thoughts?

I want to say the end links swivel all directions and can rotate and don't have to be torqued at ride height (unlike control arms for example which must be at the chassis) but could be wrong. No matter though if you did it at ride height anyhow, good practice if in doubt. In my experience they tend to clunk, not squeak, when bad. I find it unlikely to be them.

These sounds started after I put in my eibach sway bars.

I'd be looking at this more. I think for these cars the bushings (from the factory setup) are intended to grip the bar, and the bushings twist around as needed. Maybe they are slipping, and that's creating the squeaks?

(It is possible that if the bushings were also replaced as a combo with the bar that they are intended to slip, but are actually gripping instead - I've had this happen on a past car).
