Squeaking suspension
Hi all - I got a video link below with the noise I get when pushing car up and down by the suspension, rear passenger side. I can hear it while driving going over bumps etc. any thoughts?
it stays for a while randomly then goes away, totally intermittent despite the time of day, how many drives etc. i can’t find any pattern.

Before I get in trouble, let the dealership inspect and suggest a fix.
At least you have it recorded! You can duplicate it.
It clearly sounds like a rubber bushing. I would think the inside bushings of the upper or lower control arm. Could be sway-bar bushings.
I would normally would spray all the rubber bushings with WD40 but the dealership would say it has to be Silicone spray.
Buy a can of silicone, spray all rubber bushing. Move the suspension up/down as you did in video to work it in. Repeat once or twice more.
If the noise comes and goes, it could be moisture or humidity related.
Just thoughts. Best of luck getting it solved. Sucks to have these irritating noises.

List model-year, and mileage.
Maybe you can get warranty to pay, but probably not.
If you have time, you could do one bushing at a time to try to isolate which one is causing.
Spray then rock the car like you have been doing.
My thought is the sway-bar bushing or inner control arm bushing.
Changing anything should be last to avoid guessing and expensives.
Just my thoughts, someone else might have ideas.
Good luck and keep us updated.

It is within warranty so maybe that helps in just getting replacements. I guess I am thinking spraying might as well fix it, but it might come back again soon?

If it is within warranty and you can easily demonstrate the problem then why are you dicking around with it? Take it to the dealer and see what they say. Worst that can happen is that you'll be right back where you are now.

Well, I am in the UK. We have a single Corvette dealership / shop in the whole country that is very far away from me. Their reputation on fixing anything is questionable at best and don’t get me started on challenging them on anything that’s warranty based 🤣. I have to constantly think of alternative solutions whenever something happens. Especially when an issue is intermittent and I just have a gut feeling it just won’t happen when I am there, so they typically immediately dismiss it.
