The balls are no more difficult to keep in place than headset balls on a crown race. I don't worry about the pawls at all, except keeping them free of grease. Loading the lower bearings on the body (not the back of the cluster) makes assembly of the two pieces much easier.
It's the only component that does not require a fine, manual adjustment, thus making it the easiest to overhaul.
