Hey guys I have a CL55 the reason I am posting here is because the CL side of the forums is pretty inactive and this question is about the suspension itself not the abc part of it, anyways I recently got a 90k mile cl55 its perfect in every way but the driver side front suspension squeaks like crazy its super annoying, I was wondering if I can put lube somewhere to make it stop for a bit the reason I say that is because I did have a CL500 a couple months ago and the same thing was happening but I figured out where to spray wd40 and it would stop for a couple weeks. I just cant figure it out on this car for some reason. I even make a little hole on the rubber part of the bushings to fit the wd40 inside and the squeak is still there! if anyone knows where to spray this stuff while I wait for my mechanics to figure it out, the squeak is super annoying and pretty embarrassing too. I recorded a video maybe it helps thanks!

That's usually caused by a ball joint, either of 2 lowers or 1 upper.

The 1 upper where would it be located? because spraying the ones at the bottom did nothing.

could be anything. i too have the same problem...at some point i plan to refresh my entire system. bushings, ball joints, sway bar links, and sway bar bushings.

MartinWake

Yes I plan on doing that as well but I just wanted a quick fix for the meantime since I did get it to work on my previous CL. I just cant figure this one out

One of the balljoints like other members said

Yeah I sprayed it everywhere and the sound is still there

Check out:
It's a little in-depth. I had an E63 in the past that had the issue, you can purchase all of the parts needed to do a complete replacement (which you should do, remember your car is going what, 100+ miles an hour sometimes?).
