So the t-case whines loud even when the hubs are disengaged?
I don't know what T-case I swapped into my '76 Dodge Power Wagon... it was originally full-time 4WD with no lock-out hubs up front. I swapped in a later case with 2WD setting, but still have the full-time front axle, and it makes a fair bit of noise. I figured it's because the front axle is still spinning the driveshaft, which is spinning the t-case internals even though they aren't engaged. I have a later axle with lock-outs to swap in, but haven't yet.
(basically, I'm trying to convert the '76 Dodge to be outfitted like Chevys came from the factory a decade and a half earlier!)
