Introduction
Some 2007 - 2008 model year LS 460 vehicles may exhibit a wind noise condition from the front side window area when driven at highway speeds. Use
the repair procedure below to improve this condition.
It is important to note that this TSIB addresses unusual interior noises caused by slight variations in certain parts, and by carefully following the
instructions in this TSIB, these noises can be improved. Your customers must be aware that some level of wind turbulence noise, especially in cross wind
conditions, is present in all vehicles. A vehicle, such as the LS 460, which is one of the quietest vehicles on the market today, may tend to draw attention
to normal wind turbulence or rushing sounds because of the relative absence of other ambient noises.
^
