For the what it is worth department... Was piddling around today and finally was able to disassemble a bearing without destroying. One thing lead to another, the others were the stock motor bearings and the gimbal bearings. Both have grease applied, which was somewhat unexpected for the motor bearings...assumed a thin film lube.
The gimbal bearing was interesting, this was the roll axis bearing. The grease had pooled to one half of the bearing, the bottom half. I assume the grease is not of a high heat variety. Thinking how the motors can get warm and all from normal usage. But then the bearing only sees about a 120 degree rotation at most, so maybe it was gravity that pooled it to the bottom of the bearing. In either case it was interesting to see. Like I said, just piddling around.
This does kind of confirm the recommendation to not oil the motor bearings. Not knowing what type of grease and then mixing in an oil/lube could produce an adverse effect. Again I'm assuming the worse outcome based on lack of knowledge for such things. Replacing the motor bearings has been my method when I feel I have bearing issues over the last year or so. ymmv.
For those that are interested, several threads discussing bearings, lubes and their replacement. Search is your friend. Carry on...
