Do you have to replace the supercharger when it is bad?

Well, there are really only 4 options you have.

# You can buy a new one for over a thousand of dollars, which in my opinion is a waste of money. # Depending on what is wrong, you can just buy the front nose piece. # Depending on what is wrong, you can just replace the coupler in the inside. # Or you can buy a rebuild. This might be the best option since they are several hundred of dollars, however it will come with a lifetime warranty.
