Gyre 250 rotor and case slipping and loud

I have two 250s on my 200 gallon less than a year old. One of them has a rotor and bushing that are loose and moving. There is no resistance which way the guards move and the one side just moves everywhere. I can reach into the tank and move the one rotor guard anway I wish. I have taken the entire unit apart and it has been reassembled correctly and the loose rotor cage still slips and the unit is unacceptably loud.

This is the 4th gyre I have owned and I have not run I to this problem. I am hoping it's a quick fix.

Thanks felix.
