I do a mod to get grease into the slider ball, a grease zerk is fitted to the rotating swash plate locating the zerk so it aligns with the large gap in the slider ball then I drill 4 small holes in that slider ball recess then reassemble and with a very light weight grease I pump in to fill the recess  (which lubricates the entire slider ball area) keep pumping and the grease then is forced out via the 4 small holes into the rotor shaft itself thus greasing the rotor shaft.
