08MY Engine Squeak

I have a 2008 LS that has developed a subtle squeak at 60K miles when I'm between 40-50mph. I can also hear it around 5mph like when I'm at a drive thru and the sound resonates against the building. Initial diagnosis is belt and pulleys. Anyone experience similar that can pinpoint a solution? Sound went away temporarily when I sprayed the pulley with WD-40. TIA

It sounds like it is either time to change your accessory belt or one of your pulley's may have a bearing issue/needs to be changed.

Go ahead and change just the belt. Cheap and easy (like me). If the squeak is still there, then look to one of the pulleys for replacement. Could be the idler pulley, but could also be one of the others. My bet is, the squeak will go away with a new belt. They're available for about 12 bucks on Ebay. I bought a Gates belt for that price, so it's quality.
