Dang front squeaks!!
Hey MB Experts, if I may - ask for some knowledge on what appears to be an issue that is not so uncommon.
Front passenger squeaks over every bump and even when your sitting parked and turning steering wheel left and right. Handles just fine while driving. I just can't take the squeaking.
2015 c 300 4matic with 55k on it. Has the typical sound of bad mattress. Its not loud yet but loud enough to drive me mad.
I've read through other posts with similar issues and here is what I've tried so far. Used silicone spray to hit the joints in suspension on front passenger side. Tried just soapy water, even some AT Reseal on boots in case it was a boot making the noise. There are times where it almost sounds like rubber making the noise.
The squeak noise sounds like its right on the inside of the passenger tire. Any suggestions as to what to look for 1st would be much appreciated. Any common failure points that I should start with, etc......
I started to use a grease needle to puncture the sealed up parts and re-grease them but thought better since I don't want to poke a bunch holes into things if I'm unsure...which will eventually lead to me replacing that part.
Sorry if I made this too long, trying to give as much info as I could. Thank you for any direction from all you MB experts!

It is the same front right side, same exact sound and symptoms. I have a video of it too. Just need the time and garage space to pull the front right wheel off and try identify the source

I had a squeak in the LF of my RWD C300, but it was only when loading/unloading the suspension, most noticeable when getting in/out of the car. LF strut replaced & squeak was gone.
Hope yours is a easy fix as well.

Got back from the dealer and the AMG tech diagnosed it as, get this, worn paint on the inside of one of the front rims that is cavitating against the tire bead! Now that's some sleuthing 
That has to be one of the most unusual things I've heard as a cause (but all other components and the rack were silent)...apparently it's an issue that happens more often with the G Class. Will be looking to see how much a rim repair is.

I guess I should have updated this sooner. The dealer replaced the lower control arm (205-330-58-01) to get rid of the squeak. Also performed an alignment after installing the new part. Squeaking gone
