Looking at these pictures, I can see how wind noise could be generated, as well as how your fix could take care of it!

Wow, those pictures certainly put some perspective on the wind noise issue and a potential root cause. I had the wind noise TSIB performed last Friday and things seem to be much better. Still some wind noise but definitely not as prominent. I'm curious whether the dealer sealed anything in the area of the pictures. Hopefully, the TSIB will be updated as I'm a little hesitant to DIY self seal my $80k car... this isn't my bathtub

Thanks for the great work MIKE_TX... I hope Lexus does the due diligence and incorporates this into the TSIB asap.

All I did was post the pictures - all the credit for the process goes to jmcraney ... see his post above.

Thanks to both jmc & Mike

Great procedure! I presume we are looking at the exterior of the car just forward of the mirror, are we?

I believe you have sleuthed a fix which I suspect may even preclude the complicated replacement of the glass itself...

Lexus, are you reading this?

I don't know what those square/rectangular holes under the plastic piece are for, but while I was in there, I think I'd put a strip of good heavy tape or something over them, too! The sealant around the edges ought to be enough, but just for insurance ...

The square hole, rectangular hole and round hole are for alignment and locking fingers that are part of the inside back of the plastic triangle piece. Depending on what breaks off when you pull it off you will need those holes unobstructed when you put it back on. So maybe tape is not a good idea. The sealant bead pattern I depicted (the cross stripe could be a little lower) in the photo with the yellow text provides good isolation for the three alignment holes. I drove my car again today and the improvement is really stunning. I hope others experience some improvement too.

Yes, you are looking at the forward corner of the window in the right front passenger door of my 2007 LS460

What am I missing here? I thought the major problem with wind noise was on the driver's side window. However, according to the latest findings by jmcraney, there is a fix for the wind noise on the passenger's side as discussed above in detail. Can someone explain this to me? Can the same fix work on the driver's side? I am asking this because, I do have some swishing wind sound (only on the driver's side) with cross winds. It would be nice to eliminate even the swishing sound. But maybe, I am asking for too much.

I am sorry that I did not make that clear. I fixed both sides exactly the same. So I can't say whether one side provided a fix or better improvement than the other. I sort of got carried away and fixing both sides seemed like the right thing to do. The photo is of the right front door but if you need to know what the left front door looks like I could send you a mirror image of the same photo and you wouldn't know the difference.

jmcraney, I (and everyone else here) greatly appreciates your research and probable fix of what has been the longest discussion in history. If this is indeed a fix of the problem, Lexus ought to pay you at least a $million for discovering it. And I am being very serious here. Can you trade mark this fix?

Do you still have some swishing wind sound after this fix?

jmcraney

You may not have any improvement toward eliminating the swishing sound from cross winds. I think all cars have some of that under extreme conditions. My problem was roaring sound sensation up around my shoulder and poor isolation from traffic noises. The fix that I did on my car provided a big improvement for the swishing noise from cross winds but did not completely eliminate it.

Man, now were cooking with fire.......WOW great job JMCraney and Mike

I just cut and pasted this to my dealer.....Great documentation!!!!!!

JMCraney; I think your post is a great show of ingenuity, something the Japanese may be lacking in their pursuit to perfection. Posts like yours is what makes these kind of boards so great to me and I'm sure others....well done.

Talk about coincidences...

Had the TSB done Oct 2007. Came back with worse noise. Sent it back and also complained about the black triangles not being fitted well at all. Came back second time much quieter and my triangles well fitted.

Did the spring wash and wax yesterday and noticed the triangles had worked their way out of position. Was thinking to myself that I just need to pull them off and fix them right - and wondering how they were attached. Finished waxing, went inside, and read jmcarney's triangle posts for the first time.

If the triangles are part of the problem, I wonder if they might work their way out of position, which could partially explain those cars which develop wind noise after a few thousand miles.

Anyway, thanks for the pictures jmcraney!

Bob
