My guess is that the impeller has worn down around the shaft.  I have
a Fluval with a worn impeller that acts likes yours does.  Open it up
and pull the impeller out.  If it seems loose around the shaft, then
you should buy a new one.  The cost is about $13.

Here are a couple of links.  I can't vouch for either, but they have
the information you would be looking for:
