Hey guys...I just took delivery of an 06 Indigo Ink 4x4 double cab with the 6spd manual and I'm absolutely loving it. But, I'm noticing a subtle whine at highway speeds if I feather the throttle just right. It's right between load and backlash that I can hear it. I *think* it's the rear-end and not the tranny b/c as soon as I hear it, I can depress the clutch and it remains...i.e. it follows the speed of the truck, not the speed of the tranny. It's really not that big of a deal but I was just wondering if anyone else has the same whine.
