6.0 truck only has 18,000 mi. LTZ with 4.10 gear. Going down the road around 40 to 50 and you let off pedal and you hear a slight whine in the rear end. Place foot back on gas it goes away. Like you crest a hill as you start going down hill take foot off gas you hear it. Shifts fine. Anyone else hear this?
