I had a rough spot in my steering and it turned out to be the steering
box disintegrating the gears inside, had to replace the box when it locked
up, fortunately I was not out far at the Tierra Del Sol Offroad Safari, but it
did ruin my day of wheeling, driving 4 extra hours to get the replacement box
I had sitting at the house.
You should pull the top of the box off if it's a non power steering box and
see if there is a bunch of metal goop in there
