It has a 1-1/2 inch-18 fine thread and an integrated flange that acts as a locking washer to keep the yoke tight. You would replace this nut when servicing the pinion seal, U‑joints, or differential, or if the original threads are damaged. It's a common hardware item on many older heavy‑duty trucks with Rockwell/Meritor axles.
