I have a stock drive shaft. I don't know about the pilot bushing but my transmission grinds when you put it in first gear. I don't think it is the differential because the noise comes from the front/center of the car, no t from the rear. I thought of the differential but I'm sure it's not. I didn't change the pilot bushing. Tell me if you go through with changing the pilot bushing and if it does something.Thanks
