I have an '03 f-150 4x4 that runs and shifts great but makes a grinding noise when idling and going slow but disappears when I go fast, is it going to burn out or breakdown? I checked the fluid and it was good and theres no leaks, is it safe to drive?
Follow the noise to as close as you can get. Use a long screwdriver and hold it to your ear and listen. Check various components that are near the noise. By using the screwdriver when you get near the noise you will know words coming from. Just let it idle until you find it. We can start here

Why you think it's in the transfer case? Does it have a manual shift transmission?
