I am one of the owners of a 460 LWB that had the TSB done for the wind noise. When I got the car back, the wind noise was worse than ever on the driver's side now even starting at speeds above 40 mph. Before the noise was annoying above 60 mph.
A friend of mine who is an Aeronautical Engineer at Gulfstream drove the car and after inspecting the window area found that the small triangular black piece covering the bottom front of the window was extending outward from the glass leaving a small area where rushing air could penetrate.
I sealed this black strip with painters tape (see photo) and took the car out for a short test drive. I got the car up to 80 mph briefly and my initial impression is the wind noise problem is gone. I want to take it out hopefully later today when there is some wind and drive it for a more extended period.
It now makes me wonder if the TSB was successful in the first place, but they created a new problem when putting the door back together. I say this because, the passenger's side seemed much improved after the TSB. The black triangular piece on that side is much more flush with the window.
