No, I'm not sure, I'm making an educated guess based on approximate position of the noise and when I oil it (that was an effort) I'm pretty sure it stops for a little while, and its the least expensive part near there by far. If I'm wrong I can either return it or consider it preventive maintaince and exploratory surgery.
