The manual instructs to add grease on e.g. the shaft blades.

I have replaced the front shaft spool cups with a type so I don't need blades in the front.

I add a little AW grease there also, because it's metal against metal.

Do you all use grease in these places, or can I stop using it if I accept some extra wear, and replace more often.

Will I gain less friction in the drive train if I don't use the sticky AW grease?

Was talking to some Xray drivers (T4'15) and they did not use it.
