I have had many Mercedes! I have 2 E-Class and no squeaks at all. My 2011 ML550 sounds terrible when going over speed bumps as did my older one. Not sure whats up with the ML suspension but is anyone else having this squeezing and if so, what do you do about it?

I've sprayed key points with a penetrating oil and it works but only for a short period.

Thanks in advance for any input.
