2007 Mercedes SL550 77k miles
Hello everyone , having an issue with a noise coming from the suspension left from wheel well it would like that I need help locating the noise.
All struts have been replaced, but when I either sit in the car in the morning it makes like a creeping noise and there also is road noise at low speeds on uneven pavement, coming from the left wheel. No noise at high speed just low speed going through Parking lots, in between a creeking noise/something is loose or needs wd40. I have a video of the sound but it is not letting me attach it
I appreciate your help figuring this out.

low speeds to me sound like compliance components: suspension bushings, end links, balljoints, etc
definitely don't use WD40, WD = water displacement, I have rarely ever seen a use case of WD40 on a car. cars are very well documented as to where to lubricate and what to lubricate with

+1 on the bushings. Check the control arm bushes and castor arm bushes for cracking and wear. R230s are very hard on these bushes; it's a heavy car with soft rubbers. At about your mileage they start to chew them out. Get under with a bright torch and look for any cracked rubbers.

this is the sound, what do you think? I already had all four struts replaced with OEM ones so I know it’s not the struts.
