In Sink Erator-Badger 1 Leaks on the side?

I have a 5 year old Badger 1 that has a leak on the side opposite to the connector to the drain. I've taken it off and discovered that there is a crack in the plastic housing (not where the motor is) in area where the blades are. If I fill the sink, drain it and then turn on the disposal water shoots out the side. My question is, can I buy a replacement part or is it time for a new one.
thx
