My truck is currently at the dealer for some repairs, some of which are covered under warranty. One issue my truck is having is a high-pitched ringing sound which I believe is related to the drivetrain (I have a thread about it). My truck still has the 5 year/100,000 mile powertrain warranty. Obviously the service center will have to do some diagnostic work to determine what the cause of this sound is. So far they have said that they think it's being caused by a loose spare tire, but I highly doubt this. Here's my question - if this problem turns out to be drivetrain related, can they still charge me a diagnostic fee/for labor, or should the cost of the entire process be covered under the warranty?
