4WD Problems?

I have a 90 Bronco II Eddie Bauer 4WD with manual transmission. This week I started experiencing resistance when backing up and it feels like the car is in 4WD which it is not. When driving forward, the sensation of 4WD continues until occassionally a loud pop occurs and it feels like 4WD disengages. I am still able to engage 4WD with the button but am concerned that it seems to be doing so on its own. Any suggestions?

One thing I'm not clear on in your case: Is it doing this out of the blue, or after you've had it in 4WD and shifted it back into 2H? In either case, check for something that would cause binding in the drivetrain. You indicate that you have an electric shift t-case, if it's shifting on it's own, check the wiring to the shift motor and the shift motor itself to see if something funny is going on.
