Great advice Grant!
I would just like to add that if you are in a corrosive environment,
stainless steel and aluminum do not get along.

My rebuild Yaesu process:
Clean the races thoroughly. If there are some ball divots in the
aluminum, use some 180 grit sandpaper to reduce them, perfection isn't
needed. Replace the bearing balls with stainless ones from McMaster.
Lubricate with full synthetic TFE loaded SuperLube. Lightly lube the
gears also.
Getting the "timing" correct of the potentiometer vs the gears is
important. Hopefully, you marked the cases before separating and didn't
move the pot. It's confusing to get aligned if off.
If the controller pointer o-ring "drive belts" are flabbed out
(sticky/nfg pointer), my solution was to toss it into the nearest trash
and buy an RT21 from Green Heron. Fixing a Yaesu once was enough.
Yaesu mechanics are worth fixing.
