Front End Pop Sound

I have this 'popping' sound up front when I go over such things as speed bumps ... if I go over them coasting, it sounds like the vertical movement causes it - if I coast over the speed bumps with the brakes slightly engaged, the noise is less or not at all.

The front struts have been replaced with new Bilstein and I have had them checked out by a crack technician who can find nothing wrong with them. MB Dealer obviously does not like them and says they are not adjusted properly - the SR at the Dealer says he looked at them with his Tech, and observed that they were on the last setting - not properly set.

I called Bilstein and had a girl look up the ones I have and the info for my Mercedes, and she says they are the correct ones and they are not adjustable! I am seriously questioning my MB Dealer now

So, I have this popping sound when going over small bumps ... otherwise, the ride and handling is great. The Cross Strut Bushings are worn, so says my crack tech, but he says that is not the cause of the noise, even though after two hours of him testing it out (even road inside the engine to locate noise) we could not find it.

Can anyone help me with some tips ... vertical deflection causes popping sound and installing new struts did not solve the problem.

Thanks -

It could be a bad ball joint if it is comming from the front. I have already had our ball joints replaced at 70,000 miles. This appears to be a common failure.
