Thanks for your reply. I am aware of the creaking problem and have used silicone and and other lubricants to alleviate it. This is a wind noise issue and I am certain that the position of the window is the determining factor. Since I have noticed it on 2 different cars I don't think it's my imagination but the difference is very subtle and I would encourage other owners to experiment and see if they can notice anything, Maybe it's because of the double pane glass on the UL models but I'm not certain.

This isn't about wind noise from the windshield area but from the side windows. On my 2001 LS430 UL and now on my 2004 LS430 UL I have noticed the following: If the side windows are completely up (ie. as tight as they will go) they make slightly more wind noise than if I release them just a little. I do this by pushing the window switch just enough to relax the window in its seal, but not enough to open it. It's only a slight difference and it's hard to tell especially under noisy pavement or very windy conditions. Seems like its more noticeable on the front and rear drivers side windows but that may be just because I'm closer to them. Curious to know if anyone else has noticed this, and if so why does it occur?

This looks to be a good deal on a great used 2004 LS430. This one has the Ultra luxury package and also has a Lexus Certified warranty. http://www.cars.com/go/search/detail.jsp?tracktype=usedcc&csDlId=&csDgId=&listingId=53880524&listingRecNum=1&criteria=sf1Dir%3DDESC%26alMdId%3D21363%26mkId%3D20070%26stkTyp%3DU%26mdId%3D21363%26rd%3D100000%26crSrtFlds%3DstkTypId-feedSegId-mkId-mdId-cpoId-yrId%26zc%3D50450%26rn%3D0%26PMmt%3D1-1-0%26stkTypId%3D28881%26sf2Dir%3DASC%26sf1Nm%3Dprice%26yrId%3D20143%26cpo%3DY%26cpoId%3D28444%26sf2Nm%3Dmiles%26alMkId%3D20070%26rpp%3D50%26feedSegId%3D28705&aff=national
