Pump very noisy - need help

[KyleO]

My AquaMedic OceanRunner 6500 started out nice and quiet and pushing alot of water.

6 months later it is still pushing the water but is very noisy. It is like a fast, high-pitched rattle............almost a hum.

I took it apart tonight to make sure all was good internally. Gave it a good cleaning and still very noisy.

Anybody else have this issue with OceanRunners?
