I can't say that rotating the bogey arm would help the lubrication much, but taking the strain off the bogey could help the bushing "float" around the pin allowing the grease to fully fill the void & ensuring better distribution while pushing out old grease & contaminants. When my dad greased farm implements, he always pumped in grease until clean grease came out, thereby flushing the wearing surfaces of any metal fragments. Grease is much cheaper than bushings & pins in my opinion.

Richard,
My only point is that the total volume for the grease to occupy is constant
and will be filled regardless of whether it's pumped in with the suspension
arm fixed. When the suspension begins to "work", the movement of the hub
will distribute the grease.
Your point about displacing contaminants is a good one -- but who among us
does that? The "rule" is, "pump 'til you see grease coming out of both
ends of the hub". That's not enough to displace much crud. Considering
the almost total absence of seals, it would probably be a really good idea
to pump lots of grease through there -- but who wants the mess? :-)
