: On my 2002 K2500 Suburban when I am in 2WD it still sounds like some of the front-drive components are rotating (there is a sliht whine and I can feel the vibration).
Quite a while back a poster who worked at a dealer claimed the front DS turns on auto trac trucks due to friction in the t-case clutch pack even when disengaged. If so, it's a stupid design. He did verify as I said, the DS does NOT turn in the case on non-auto trac.
