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.

^ Part 1 of the repair procedure (install EPT foam to various locations) applies ONLY to 2007 model year vehicles produced BEFORE the Production Change VIN shown in the Production Change Information table.

^ Part 2 of the repair procedure (install laminated glass) applies to all 2007 model year LS 460 (standard wheelbase) vehicles, and to 2008 model year vehicles up to the 2008 model year VIN break shown in the Production Change information table.
