Hello Steve
What I have done in the past
Is to degrease it all and before assembly,drill and tap grease nipples in 
the housing,just make sure you clean all the filings before assembly.Then 
for regular maintenance you just have to give them a small shot of grease 
with a regular grease gun.
Just a suggestion
Good luck
