They, Lexus, were desperate for solutions and were trying everything in 2007 - that is well documented in this forum.

Turns out the wind noise problems were caused by a trim defect on the front doors.

As far as I know, Lexus will not help you with wind noise issues.

Some owners have found relief with a DIY repair, check here: https://www.clublexus.com/forums/ls-...noise-fix.html

I am not sure if non Lexus OEM windshield can be the cause of the wind noise, or maybe it was a bad installation. Regarding the sunroof I don't think it is the sources because when I close or open the sunroof cabin liner the noise level stays the same, I used to have some noise from the sunroof in my previous 2010 LS 460 and when I close the sunroof cabin liner the noise would go away.

How can I isolate noise related to the windshield? Should I tape the entire perimeter of the windshield? I am going to also tape the driver window triangle sides just to eliminate as potential root cause. Thanks.

I would think that duct tape or masking tape would be poor choices because of adhesive residue. A better choice might be the ubiquitous 2" clear packaging tape - it's not expensive and is readily available. You shouldn't leave any tape on very long. Be sure to tape all areas simultaneously as noise from multiple sources give confusing indications.

The LS460 has two roof mouldings that go over the windshield, which are panted. Under these mouldings are rubber gaskets that are designed to make flush contact with the windshield. If these are not present or are not pressed against the windshield, that is a source of wind noise. Also, the lack of underside plugs can cause noises that seem to come from the windshield area.

Just wanted to bump this up, not sure how many of you actually looked at the TSB that Lexus performed for the wind noise, but it is EXTENSIVE. The triangle is the least modified thing, where they add additional EPT foam to the edges and form-in-place gasket around the clips. The whole upper frame of the door is removed, where they then add EPT foam along the bottom edge window molding, EPT up the entire length of the trailing vertical edge of the window opening, EPT below that to keep more wind out, EPT inside the chrome areas behind where the rear triangle is, along with gluing on a rubber stabilizer for the secondary window seal at the base of the window (which adds additional pressure to the seal when it is in the up position). EPT is added to the front and rear of the window runs, as well as under the body-color moldings that run along the edges of the windshield. Finally, more EPT is put behind the area of the triangle mounting area.

Most of this can be done DIY, with the worst part being that to fully complete it you will have to drill out three rivets and later rivet them back into place. The second worst part is removing the glass, as we know this is always a potential to break a very expensive piece.
However, anyone with even a modest mechanical background could most certainly complete parts of this TSB without doing either of those: you can lower the window all the way to glue on the rubber stabilizer for that secondary lower seal (this is currently a late-night presumption, I will verify the validity of this statement later), you can remove the gloss black vertical window trim and install the EPT foam back here, you could install the additional EPT in the window run areas denoted on page 11580, then you can ignore the triangle modifications and just do the Jmcraney fix. Finally, buy four clips for each side of the windshield molding and install the foam at the base as it shows.

The rubber stabilizer modification (it is effectively a rubber bump stop) could also explain part of the reason of the "fix" of bumping down the window a tad, as you would be relieving some pressure from that secondary seal that may be allowing air to pass inside as it gets pushed too far inward.

75793-50010 is the part number for the foam kit. $8 and you don't have to try to hunt down all the different types of EPT.

I did this whole repair years ago on my other '07, but I bought another '07 and of course it needs some silent treatment 😄

I found the part numbers for the "regular" flat triangles, but looking for the updated version.

Thx in advance!
