I've got the silencer tubes put on and no longer have the metallic clunking when going over bumps but my suspension still makes a lot of noise over rough surface compared to my mom's Chrysler minivan. Dealer did not change the dampers but the sounds actually comes from all four wheels, louder in the front (same both sides). It sounds like tires hitting against the bumps, which makes me think that this is normal characteristic of MDX, and not due to suspension problems. MDX also feels like it vibrates a lot over rough roads, like it has really stiff suspensions, but they aren't all that great during cornering either. Is this somewhat characteristic of Honda's and Acura's? I'm thinking about test driving a demo sometime, but was curious to see what other people with previous experiences with Hondas thought about this. Otherwise, I think MDX is the best suv for the money. Thanks.
