Hello.
My 05 G35 Coupe makes noise. It sounds like something is not
tighten well under the body.
I can hear axle or something viobrating when I drive rough road with window open. I don't hear this kind of sound on other vechile with the same condition.
Something is loosen under the body. Or is there TSB for this?
Thanks in advance

 

I had one of the plastic pieces on the inside of the front wheel well come loose, and rattle on rough roads. They are just held on with those little plastic retainer clips.
