May sound crazy but attach a wire brush to a stick and rub it in and out of each axle half. I mixed up some purple power and "flushed" mine. You would also be surprised what a hose pipe with a nozzle on it will do to "move" debris out of the housing.
It surely will not rust. I did use a can of brake cleaner inside the center section.

If you don't want to go to all that trouble just soak a rag with some cleaner and run it through the housing....all depend on just how bad it is.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
