Which transfer case do I have?

No luck with disconnecting the brown wire. I still have the gear whine after 45 MPH when I let off the gas. If a keep the RPMs above 1K, it wont make a noise. I guess it's back to the gear shop to have them take a look at the transfer case. Any chance this could be the transmission?

Have you checked your differential fluids?
