Is the impeller wobbling in the pump? People have successfully used the Red Devil pump as a replacement.

The impeller has stack in pump because i had to use skimmer over 2 years. I tried with vinegar and with force power to take it out but nithing. Yea i have read that some people have used that pump but i wana someone tell me hiw expirience.
If the replacement is easy or need something else to do. If the pump is good for the this skimmer and if its noisy.
