My C320 squeaks when I go over any bumps. How do I get that to stop? Spray lubricant?

 

Of course, it all depends on locating the source of the squeak. If it's coming from the front suspension, you might look at the front control arm bushings. Mine were squeaky on my C230K and I sprayed the heck out of the rubber bushings with spray silicone
and that helped, but.....if they are worn out, they need to be replaced. This is only one source of noise....there are obviously others.

 

Yea, that's what I thought. I don't think they are worn out, prolly just dry. The car only has 67k miles on it so they still should be in good shape. I will just have to spray the suspension bushings with silicone.
Thanks for the advice

 

Got the squeak fixed. It turns out it was the front tie rod ends and Sway bar end links were worn. All covered under warranty.
