Hey Guys,
The stearing/suspension is making this rubber squeaking noise, when I go over bumps and turns on my C320. Has anyone else delt, with this, and is there an easy way to take care of this? I know on a E430 we had a similiar noise, and mercedes eventaully had to replace a bunch of stuff....
Any thoughts, on what it might be besides a trip to the M dealership. I do all my own oil changes, etc, and I was wondering if this might be something quite easy to gease, etc. I've already given the underside a quick looking over, and didn't see any obvious, zerts, etc.
Thanks,
Adam

Yeah, this is a pretty common one. When you take it in they'll probably either lube or replace a bushing. Mine did it at 15K miles and they lubed it but it came back and they had to replace it. It came back again at 35K and they lubed it and it went away. I heard rumors that they were making a new bushing to replace the original part on cars with the issue, but that could be hearsay. Basically dirt and grime gets in the bushing and it squeaks really bad. Mine got worse as the temperature got warmer and especially when I drove in stop & go traffic. Your dealer will be able to sort you out though.

If you're absolutely adamant about not going to the dealer, get under the car and use some silicone spray on all of the suspension bushings, especially those connecting the sway bar.

As noted above, this has been a not uncommon problem, and there may be new parts out there to deal with it more permanently than squirting it regularly.
