Marineland Magnum 350 Problem, help!

I got this used Marineland Magnum 350. The propeller is rocking back and forth. Anybody know what to do to get it to run smooth?

I don't have a Mag 350 so this is general speculation.
There should be rubber tips on the end of the impeller shaft that fit into a hole in the impeller well and into the center of the impeller cover. If one of those was missing it could wobble around.

Thanks for the suggestion. I put all of the parts together and now it works great. There is 1 part inside that sits on top of the propeller. That is what made the difference. I decided I prefer my Eheim ecco instead of the Marineland. For the Eheim is much quieter.
