The seal needs to be replaced but i have to remove the impeller to do so
Most impellers are simply thread on. in most cases, there is a flat spot or allen key insert at the back end of the motor shaft. this allows you to hold the shaft in place as you unscrew the impeller by hand
SOURCE: pump seals
The impeller is threaded on to the shaft. The trick is to hold the shaft in order to untread the impeller. The surest method is to disassemble the back of the motor, exposing the opposite end of the shaft. There should be a spot to put a wrench in order to hold the shaft immobile. Then, it's simply a matter of unthreading the shaft. A strap wrench does a great job of holding the impeller without damaging it.

You have to remove the back cover from the motor. Next loosen the capacitor. Put a 7/16" wrench on the shaft and the pump impeller will screw off by hand.

Thank you for posting your question here on Fixya.com.
Neither...it is threaded onto the motor shaft. Lock the shaft at the end opposite the impeller and turn it off counter clockwise.
