Just a random thought I had this morning.
Went in the trunk where the bar came through the trunk floor--drilled 1/4 holes on each bar (around toward the back side) --filled it with expanding foam---made a HUGE difference in the noise. I wonder if I had went inside and drilled a few holes to allow the air to escape (not build pressure) would it have taken more foam. Definitely worth the trouble.
