Scale of 1(easy) to 10, about 9.5 without the correct puller.
Without that tool you will need to remove the COMPLETE hub & have the flange pressed from the bearing. & then the bearing pressed out & then a new one back in. ON installing the flange back into the bearing the inner race MUST be supported or the new bearing will be destroyed as well.
