I am working on a RC-7589 right now that was very noisy when I first got it going. After the bath (washed off most of the red dot pattern whirligig) and oil soak it is pretty quiet but the bearings must be shot as it has a pretty serious wobble. The play seems to be mostly in the bushing on the gearbox side.
I picked up that Zoom oil at the hardware store last year, the description seemed like it would be good stuff. Since these mechanisms use a combination of metal and plastic gears it is important to use something that will not harm plastic.
