'06 ML350 noisy interior
 

hello!pardon me of my ignorance. can anybody help me/give me info on how to solve my problem. am in a dilemna now! just recently got an ML350 but is now sufferring from the silly noise coming from the sunroof to the ceiling. the sound of a metal sheet vibrating and i felt the car is going to crash everytime i pass on an uneven pave and small potholes. the large ones are ok but what's terrible is the small ones. would it be because the tire am using is 18" instead of the standard 17"? at first the tire pressure was placed at 42 no wonder it was so stiff. i changed it to 32 psi and ride improved a lot! but not quite Benz quality and i even compare it to my Prado and by all means it was better. the ride of the ML really sucks do not know why????i test droved it before and it was perfect?????can anybody help me????

Isn't he sun roof on the ceiling?

It may need a tire rotation, I don't think the rotors would be an issue already.
