This is a really old post, but I think I know what happened - ie, the same thing that happened to me.

There is supposed to be a small rubber bushing at BOTH ends of the ceramic shaft. However, the bottom one is usually stuck inside the impeller chamber. I almost gaurantee that you knocked is out and flushed it down the drain while scrubbing out the gunk in there.

I bought replacement bushings, and my filter was instantly silent again.

I think you will find there was something else wrong. Could you have not put it together properly but when you removed it and vassoed it- it was then put together properly. I have 6 eheims and always clean the impellor/ shaft everything. Only time i got noise was when i had not fitted everything properly

Good to know, but vaseline was the only thing I had on hand and it was either use it or keep the filter off. Next time I'll use something else, but I'm hoping there won't be a next time.

Cleaning out the sludge/slime was definitely the cause of the noise. It must have either a) removed the natural lubrication or b) unbalanced the impeller or c) both of the above. Take my word on it, thoroughly cleaning out the impeller housing is probably not the best idea.

While I have not experienced this loud noise after...

While I have not experienced this loud noise after cleaning (I did break the ceramic shaft once though...), I would not recommend using vaseline. I work in the water treatment industry and have found that vaseline as a sealant or lubricant can have adverse long term effects on rubber parts (such as the ends of the ceramic shaft) and seals.

There are commercially available silicone base sealant/lubricants that would be a better solution, such as DOW111.

Fit here,

Im using classic 2217 as well for almost a year now and did cleaned the filter 3 times, snapped my impeller shaft once. I agreed with Ranga, its strange that the loud noise appear after cleaning.. I never face one. You might need to check back whats the real cause.

That sounds strange. I've never had that problem before. It couldn't have sounded noisy when you used it new, right?
