What the heck is this?
A chirping under the hood that can only be heard while driving. The faster I go the more chirping/squeaking I hear, but when I try to diagnose it while its idling I can't hear it. It's driving me crazy. It seems to chirp/squeak more on rough pavement when the car is vibrating more.
I've done extensive searching on this forum but can't find anyone whose belts/pulleys only squeaked while driving. I did notice my crank pulley very slightly wobbling, but I think its a normal amount and I'm not convinced thats the problem. Idler pulley maybe? Tensioner? Has anyone else experienced this?

A/C belt huh? Any way to verify this before I take it into the shop? Why would the A/C belt be more prone to chirping while driving, but not at idle, than the drive belt (or whatever the front belt is called)

Lubed up the A/C belt the best I could this morning but she chirped like crazy all the way to work, and silent as ever at idle. Could it be a tensioner arm bouncing more when the car is vibrating at speed?
