Welcome to the site.
Since the noise goes away when you install the fwd fuse, it is your transfer clutches causing the binding.
The first thing you want to do, depending on the noise, is go to a hard surface parking lot and make slow figure eights with the fuse NOT installed.
Since your car sat for a few months, the clutch plates could be sticking, making your car FOUR wheel drine, not ALL wheel drive.
By driving in small, slow circles or figure eights, you might get lucky and break the sticking plates free.
However, if the noise is broken parts, you are only tearing stuff up more.
If you can check your Throttle Position Switch, and find out what the voltage is there, you might have only a small, easily remidied problem. Tom
