New 6.0 2500 with a question.
Kind of a tech question, but kind of a new to the truck question. I just bought a new 2012 2500 LT with 6.0L gas motor. I have one issue with the truck so far. When I turn the steering wheel while the truck is moving I hear a hissing noise. Ive never heard this on any vehicle while it is in motion. Usually I would hear this while at a stand still and turning the wheel too far to one side. Its noticible at speed with the radio on and drives me nuts mostly because its a new vehicle. This is my first HD truck so my question is, is this normal on the newer HD trucks? It doesnt do it while sitting at park is what is throwing me off. The truck has like 500 miles on it now, and I feel like there couldnt be something wrong with the pump already could there? Before I take it in to the dealership I thought id pick the brains of some Chevy vets.

Mine makes noise...9,000 miles on the clock. Its not bad, but you can hear it with the windows down...
It wouldn't be a pump issue, it would be the pressure relief spring if anything...
