Rear Hub removal
Discussion
Have the bearings been packed with grease? They usually only have a smear added on assembly and could do with some more... but that 'some more' is down to feel, as too much creates a hydraulic wedge that prevents the balls from rolling and instead they slide round the races which heats them up and causes the case-hardening to break down. So a good fingery slurp of (e.g. Castrol LM) lithium grease, forced in between the split inner races is no bad thing.
I can see Wild Rover's point about anti-corrosion but in theory and with perfect production tolerances, the inner races should be such a close fit on the shaft that any grease would be wiped off as you push the stub through and no moisture could penetrate past the inner and outer seals. I've always understood that splines should be dry or at most oiled, not greased. Nobody ever says to grease the splines on a gearbox input shaft so that the clutch plate can slide more easily
