Penguin 330 Filter

I've had this filter for about 8 years and it's served me well, but it's started making a vibrating noise. I cleaned it out, impeller and all, and that did nothing. It still works fine, it's just annoying to listen to. So I was just wondering if anybody has had problems with noise with this filter and how they fixed it? If nothing else, it may just be time for a new one but I'll take a cheaper solution if I can get it!

What causes the vibrating noise is actually the rubber bushing on either end of the impeller.
You can clean them as much as you want, but it will still oscillate and make noise.
Either buy parts, or a new HOB

So if I got a new impeller would that fix it? That's really the only working part you even can replace, as the rest is encased in the filter.
