Something is squeeling under the hood of my truck. I've replaced the belt, the belt tensioner twice, and the idler pulley. I dont think it the water pump either, but what I do know is the when I turn on the air conditioner is gets worse, especially on rainy days. My truck looks and runs great other than that squeel.

You need to recheck all idler pulleys and make note of the alignment of the belt. Look for the tensioner being crooked a little, also note the power swteering pulley to make sure its aligned correctly.
