The seal is under the bearing. You need to remove the bearing first to replace the seal. Heating the bearing retainer expands where the seal and bearing goes. The cool temperature in the freezer will cause the bearing to become smaller. Not necessary for the seal but it wouldn’t hurt anything either. Even though its a minuscule amount its enough that the seal and the cooled bearing will just slip right into the hot bearing retainer. You need to be quick. Once they come in contact with each other, everything starts to reverse.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
