Ok, let me see if I can jump in here and play catch up. I tried to read back a bit and there seems to be a few different issues/things going on.
I had my first experience with a SWB LS the other day. I had the luck of pawning them off on my other diagnostic guys, but it didnt last.
There seem to be a couple issues with the wind noise. I didnt read really hard into this thread, just tried to scan through since theres so much writing in here.
The first step in the TSIB is to check for missing body plugs. To clear this up, there are 4 of them located in each corner of the wheelbase. Its hard to see from the ground (as MikeTX's pictures suggest). It says "If they are missing, replace them and road test the vehicle. If the nosie is gone, do not go further with this TSIB".
You guys already know, installing laminated glass into the front doors is part of the TSIB. I believe this solves the
MAJORITY of the noise. When I test drove this particular vehicle, I felt as if the window was not completely closed, although it was. The windnoise was horrible.
A brief rundown of the TSIB. You remove the chrome piece of the exterior door trim, and install foam in new places, and replace other pieces already there in an effort to block off air rushing through the door. Next, you install new clips that hold down the body colored peices of trim that run parallel with the A-pillar and the windshield, also installing foam down inside of the fender in an attempt to reduce air coming through the interior of the A-pillar itself.
Now some of you are concerned with turbulence noise around the mirrors. What my dealership has been doing is having our 3M guy install a little bit of the 3M bra material around the light at the bottom of the mirror. It is just enough to cover the entire light, and the edges around it in an attempt to make it more aerodynamic. Now I offer this information, but take note that some dealerships may NOT be able to perform this, and it sometimes does not cure this issue. We acknowledge it, and attemp to dampen it, but its not perfect.
After spending a day in a half (not as simple as it sounds when typed out) working on this car, I test drove the vehicle. I was not satisfied with the noise levels, although they were dampened. The day was an abnormally windy day which I believe contributed to the higher levels of noise. I grabbed my Diagnostic Specialist and took him for a ride. Having experience with many other LS's, he said that was simply the best we could do, and that he would meet with the customer to discuss the issue.
My thoughts are that, yes, there is SOME abnormal wind noise levels, but most cars have wind noise. As you lower general ambient noise levels in the cabin, other rattles, creaks, and wind noises become more obivous. This is not an excuse, but rather an explanation. I think Lexus is going in the right direction on this issue, but theres still some work to be done. They are well aware of the issue and are working to resolve it. I know that much.

Have some sympathy for those techs man, its not a fun job. Its very, very involved.
