The truck is an '04 w/LB7 with 3600 miles. In the last week the truck has developed a random squeek while idleing in park/drive and while low rpm crusing(almost sounds like an alt. bearing but completely random). Looking under the hood I can't pinpont the sound.I know I could take it to the dealer under warranty but I am trying to avoid removing my juice/attitude and I can't find a dealer in the area with an actual diesel mechanic. Thanks in advance.
