Clicking is usually your birfields.

Tires scrubbing even when the center diff isn’t engaged usually means your viscous coupler has locked up.

Clicking as mentioned above is generally your Birfs.

If in the rear....perhaps an Auto locker installed in the diff there.

Is this something that just started?

Re your rear tires dragging when you turn: your viscous coupler is shot.

Remove it. Use search. There is a detailed thread with pics that shows you how to do it.

Don’t take it to a mechanic because most will tell you you need it and they are very expensive to replace. You do not need it.

It was one of the first jobs I did on my own rig. It’s not bad.

Agreed, my 97 was exactly as you describe when I got it. Pulled the VC as step one, this eliminated the tire drag. Installed a CDL switch at the same time. I swapped my birfields from side to side when I rebuilt the front axle and this eliminated the clicking.
