Wind Noise Fix (Roof Rack)

Sorry if this is a dupe, but I've been fighting some major wind noise (cross-wind sound, like a loud whooshing) for the past few weeks after adding 33" ATs and a roof rack. Under 65mph, I'd get very little noise, and the ride was tolerable. The second I went over 65, it became noisy enough that it was annoying the shit out of me.

The noise seemed like it was coming from the passenger side door, so I tried all sorts of tricks with tubing and rubber gaskets all the way around, but didn't have any major breakthroughs until I finally figured out that almost all the sound was coming from the sunroof.

If you don't have the following, this probably doesn't apply to you:
- Sunroof
- Roof Rack
- A general expectation of never/rarely actually opening the sunroof.

Materials:
Second Skin Luxury Liner Pro MLV - this comes in a pretty long sheet, about 1/2" thick. You'll need to cut it down to fit. -

$85 Second Skin Luxury Liner Pro - 2 in 1 Sound Insulation for Cars - Mass Loaded Vinyl and Closed Cell Foam - MLV Noise Barrier Made in USA (1 Sheet)

Knife/Scissors

Measurement to cut:
31"x16" Fits perfectly in the gap between the sunroof and the slide panel

The overall idea is that you cut to fit, then slide the panel to the sunroof about halfway back. You can slide the rear of the MLV sheet as far back as it'll go, then bring it forward and rest on top of the front lip where the slider panel sits. The sheet should be adjusted width/length-wise so that it's completely covering the slide panel, but still resting the edges on the raised sections around the perimeter. You should then be able to close the panel.

This fits very snugly, without any shuffling, and actually blocks almost all the extra wind noise I was getting. I just took it up to 85, and while I could still hear it faintly, even with the radio off and no AC the ride was comfortable again.

This MLV panel can then be removed as needed, since there's no adhesive. Just stick it up there when you need it (typically longer trips), pull it down when you don't. The main thing is that there are two sides to the liner, rigid and foam. Place the rigid side face up to the window, so that you don't have the foam melting due to the sunlight on it.

Don't have any pictures, but I can take some if needed. Anyway, hope this helps someone else with the same issue.
