So I have a 93 4x4 4.6 single cab short bed lever 4x4 on the floor. It makes a loud whirring noise when driving. The noise gets louder at a slow speed, it's like a vibration whirring noise. 4x4 engages well and disengages fine. Tranny fluid level is good, pumpkins fluid is good, I replaced front wheel bearings but the noise is still there. Seems to shift fine. Pan gasket does leak a little bit but not drastically. No shavings in either pumpkin. Are there transfer case bearings? Doe it have anything to do with my vacuum actuator? It feels like bad bearings kind of sound.

Can you post a video of the sound?

I will whan I can get back to my house to take one. A friend of mine thinks the vacuum line isn't completely disengaging the 4x4. Front shaft doesn't turn freely like my other 4x4 it's a 95
