Just added gear oil to my intermediate bearings on my 2017 SX210.
I unscrewed the zerks ( checked the old grease was not hard) and added gear oil with a syringe as others have recommended.
Just FYI ran into some trouble because as I added the gear oil the air tried to escape from the bearings causing a bubble that limited the amount of oil that would flow and was a little more mess than I was planning.....was hard to tell if it was full. I had some small plastic tubing that I would put in the hole lightly that would help the air escape...but it's also hard to reach all the way back to this spot in the engine compartment and see what you are doing.
Not sure how I wll go about doing this next time, maybe I will unscrew the zerks and temporary install a fitting with some type of tube that I can fill with gear oil, let it sit and let it take it's time "dripping" into the bearing as any air slowly escapes back up the tube and than put the zerk back on.
Maybe someone has a suggestion or a method they used that worked better for them?
