Hi,

When I am passing over small (less than fourth of the inch) bumbs on the road, I hear high pitched sound in the cabin. Sound is interminient, and similar to the sound that you have when you open or close house door in the need for lubrication. It appears like it is comming from the cabin (or something from front that is close to cabin) - opening window does not make it easier to hear.

Interesting thing is that I have to drive to hear that sound, because when car is stopped (and engine running) and when I push car down (on any of the wheels) or laterally there is no sound.

Furthermore, when I am passing over large bumbs (like those that you have on the parking spaces or around pedestrian crosswalk), there is no sound. In order to hear sound, bump has to be very small. The easiest time to hear the problem is driving on the avarage highway.

Did anybody experienced similar problem and what was it?

Thanks in advance.
