maxi jet clatter after clean up - why?

[SirToppemHat]

My modded maxi jets are in my tank working properly. I take one out and run it in vinegar. After, I take it apart and clean it. When I put it back together it makes a terrible clatter. Now I can't get it put back together where it runs smoothly like it did before. It happens everytime. What gives??

^^Need some help, I'm down a powerhead.

Did the impeller separate?

I'm not sure, I didn't really take anything apart except the cover and removed the magnet to wipe it off. Here is what it looks likehttp://www.tritonaquatics.com/index_files/Page676.htm

I just had the same and had to toss it as could not stand the noise it was making.
