bad throwout bearing?????

Ok so took transmission out and I saw that the tip of the input shaft where it goes into the pilot bushing was starting to gaul. Talked to my tranny guy and he said the pilot bushing was not pure brass, some bushings were magnetic cuz they had some metal in them and they get so the shaft starts to pick up the metal, gauls,then will actually start to weld itself to the shaft. Well thank god it did not get that bad. So I polished the shaft and replaced it with a pure brass bushing. Back on the road and no noise so far, knock on wood pretty sure it's fixed
