Suspension squeaks on hard bumps
I just noticed that I've got a squeak coming from my front suspension when I hit a quick bump in the road like a bad pothole repair or a tree root bump. The shock seems fine, there is no clicking like a broken shock valve and rebound is smooth. Anyone else with this type of problem yet before I take it in?

Hmm, I think I've got something different. I'm coming up for my "A" service in a couple of weeks, and I've noticed a slight "rubbery" squeak when I make a turn or go over a gentle bump (like a speed bump) and the body weight shifts. Sounds like the front struts maybe -- I'm wondering if they just need lubing. I've got 9K miles and just started noticing it a few weeks ago.

Hey guys - I had the exact same problem, and I think some others had it too a while back. I demonstrated to my dealer by pushing down on the front of the car while it was off and parked. It still made the squeak. They lubed a bushing of some sort but it didn't work. I called my rep and told him and he said the bushing would have to be replaced. They ordered a new one and replaced it a week later and the sound is gone THANK HEAVENS. Much more time with that squeak and I'd have gone mad.
Good luck!

Just kidding, but the line sounded pretty funny when taken out of it's context. Sorry!

Hey guys, I know what it is....I have the exact same problem.
Its the "Sway Bar Bushing". I took my car in for service a couple of weeks ago and my advisor showed me their latest bulletin for the C-class. You will only hear the rubbing sound after your car have been driven for a while, right? Putting lubricant to the bushing will not help, according to the bulletin, sands/dirt are gathered inside the bushing and when its warm, it will generate some rubbing sound for some reason. MB has designed a new bushing but its not available yet. My advisor said he will call me to replace the new bushings when they arrive. In the meantime, he changed a set of new bushings for me but he said the noise might come back after the bushing has gathered enough dirt inside.
If you guys cant bear with the rubbing sound, ask yr dealer to change the bushings for you, otherwise, wait for the new bushings to arrive!
I think Mbtech 208 must have more detailed info regarding this...

I had the same thing.
Spraying silicone lubricant didn't help.
They also replaced the front shocks (I think) that didn't help.
On my 3rd visit the shop foreman removed these bushings and applied the lubricant on their inner surface (maybe even on the sway bar too) and put back the bushings. No squeaks since than and it was about 2 months ago.
