Transfer case Whine
This has been a pretty nasty month or so for my truck, but Ive noticed that since this winter has ended, my transfer case makes a whining noise that is speed dependent. Sounds quite similar to having a manual in first gear and letting it engine brake. And it is hesitant to disengage 4wheel. However if I hit a bump, there is a thud and 4wheel disengages and the whine stops. Ill try to take a video of it later. I'm getting my xfer case flushed on Monday when I get my alignment, but any ideas what might be causing this noise? I'm not sure if I am gonna feel confident to use my 4wheel while it is making this racket. Any help is appreciated.
